WOW, responses! I have been following along on PSP for a few yrs. and have finally joined. I like PSP and have gathered alot of info from here. Thanks, everyone for sharing! I will be working on my profile and pics, but briefly I will highlight what I have: 1) '79 T/A w/4spd (ST-10)., WS-6, n.o.m. RAM-AIR III (blown-up),no t-tops, no a.c., no p.w./p.l. 2) '71 Lemans Sport (Calif. car, non-running, no rust), built TH400, 12-bolt rear(Olds?), Pontiac 350(stock), a.c. 3) '75 Grand Prix SJ (original 75,000 mi. from Fla. (rusty from living it's life by the ocean), 455/TH400. The T/A and Lemans are "keepers" and the G.P. I bought just for the engine. The plan was to swap the 455 from the G.P. for the Lemans' 350, get the G.P. running and peddle it. But then, I blew the T/A's 400. A friend was selling a relatively low mi. Cadillac 500 c.i. engine, which I bought with the intent of putting that in the Lemans (sacrilege?) and then the 455 into the T/A. Now keep in mind, I accumulated this stuff 10-13 yrs. ago. Then Life got in the way...(sound familiar?). I have since acquired a "period correct" 400 (non-thin casting) engine w/6X-4 heads that needs a rebuild, another set of 6X-4 heads and various other parts. I won't know the condition of the T/A's RAM-AIR III engine until I pull it and tear it down. So, sorry for being so long with this, but in a nutshell, I am ready to proceed, starting with the Grand Prix. Also, my goal for the Lemans is to make it a nice, dependable cruiser, yet fast enough to not embarrass me. And, the T/A to be a dependable high 11's-low 12 sec. street/strip car. Thanks for any suggestions anyone my have, and I'm glad that I finally joined your "club"! Pontiac Street Performance is a great site and hopefully it and the Pontiac legend will be around a long time!

Welcome. Thanks for posting your projects.

Out of curiousity, is the engine in the t/a an actual 69-70 ram air 3 then? Or is it the original w72 for the car?

LOL. Not the first person wanting to shoe-horn a Caddy engine into something. Sometimes we use what we have. I have a 1970 455 Olds w-34 engine in a 71 chevelle. Olds has been in the car longer now than the SBC was from the factory.

Sounds like you have some great short blocks to start with now. If your going to sell the GP: versus doing the 350 swap. My guess is it is worth enough being a original 455sj that you could keep it together, and it would be worth more than enough additional with the original engine to buy the engine parts to turn the 400s into stroker engines. When you can buy a 4 or 4.25 stroker crank for 300 dollars, no longer any reason to start with a 455.

Thanks for the welcomes, all. Jay, in regards to your reply about the GP, I have thought long and hard about this. I bought the car over 10 yrs. ago for the engine. I don't think that affordable stroker kits were available then. Keep in mind that this car, even though it is original, is very rusty (qtrs., fr. fenders, floor, trunk, even the hood!). It's interior needs: dash pad, carpet, seat covers, etc. It does have good glass and trim, though. I really wonder if the car is worth restoring. It would make a good "parts car" or "driver". I took an early retirement from Ford (gasp!) and am living on a fixed income (partial pension and S.S.Disability), so I have to work with what I have... I guess I could get it re-running and try to sell it the way it is. But, I need to get it out of the garage by Spring, one way or the other. Also, the Pontiac 350 doesn't fit into any plan except for in the GP. Thanks again, and Merry Christmas to everyone!

Kevin it sounds like your on the right track if the GP is that rusty. Bang for the buck it is hard to beat a 455. Through the 6x-4 heads on it, with a better cam, rering job if it needs it, put it in one of the cars and have some fun. Merry Christmas and Happy New Year! Jay

Re: Grand Prix SJ. I sold the Caddy 500 c.i./trans. over Christmas. Got $900 for them (paid $300), not bad! Will put the $$$ in my Pontiac fund. After considering everyone's advice, I think the option of keeping the GP's 455 and putting the 350 into it is the best one. Once it is running and some bugs sorted out, I'll sell the GP for whatever I can get. Then concentrate on the T/A. I still don't know exactly which 400 is in it now or what damage was done when I blew it. The "YS" stamping at the front of the block suggest it isn't anything special. I thought that the friend that I bought the car from said it is a RA III, but the more I think about it, I think he said the heads were RA IIIs. Anyway, I also have another mid '70's 400 (non-"557") that would be "correct" for a '79 T/A w/4 spd. This engine has the 6X-4 heads and I have another set of bare "virgin" 6X-4 heads. So, I have various options available. Whichever way I go, the motors will be rebuilt using quality parts and machining processes. I'm leaning towards the 455 in the Lemans and the 400 currently in the T/A (if savable) built for street/strip. The other 400 just keep it to go with the T/A in case myself or someone else wants to restore the car in the future. I hope that everyone enjoyed the Holidays and their New Year gets off to a good start! I'd like to hear your suggestions...

Sounds like you did well selling the caddy.

The 455 might be in pretty decent shape looking at the miles the car had. It might not need much for machine work. May be able to consider just rings and bearings and put it in the one of the cars. Lee Atkinson has a 455 build here on psp that IRC, was rerung and put together with a custom cam and stock valve terrain.

Then you could use the machine work toward a 400 stroker for the future 11-12 second engine. Many times by the time you start doing the machine work on used parts you get close to just buying new. Some of the new cranks and rods need machining to get them in spec. That is the only risk.

Have you checked the the head identication numbers on the engine in the t/a? Jay

Still trying to find time to work on the GP and get it out of here!

Jay, I have tried to determine exactly what 400 is in my T/A. Looks like a non-RAIII block, but my friend who built the engine says the heads are definitely RAIIIs. Won't know for sure until I get the motor on a stand. He says that alot of quality machine work went into that shortblock. He had sold the car to a kid, who overreved it and had probably spun a rod bearing. My friend bought the car back at a steep discount. I bought it with the rod knock. I was pulling the car off my trailer in the driveway and it stalled. While trying to re-start it, my nosey neighbor came over trying to tell me what to do. When he had me @$##%&off, I got it running and proceeded to pull a holeshot with him standing right next to me. Well, the engine blew, but I didn't care because the look on his face was priceless!!! Anyway, I hope that the block and crank are salvageable. If not, I have the other 400 to work with.

Ray, I'm working towards the T/A! Takes time and $$$, you know!

FWIW, The RA 3 heads seem to be worth pretty good money to the ram air 3 restoration projects. Most sources list the 68-70 d ports for 400 4bbl engines as the same cc head volume. But the number 48 and 12 (RA 3) usually had a little smaller chamber than the other d ports the same vintage, even though they are all rated at 72-75. Those seem to run closer to 72, the others d ports those years 62 and 13 seems to run more in the 75-78 cc range. I am not sure what they did on the 1968 engines. Pontiacs coding system on blocks and heads can become a treasure hunt. Jay

Thanks for the info, Jay. Once I determine just which heads they are, if the are RA IIIs, I may try to sell them and go with aluminum. Just curious, are you working on anything yourself?

My Pontiac projects are pretty similar to yours. I have a 77 T/A , silver/red interior 4 speed car that is a numbers matching car, I have the engine out right now, and am going back together. Then also have a 71 cardinal red, black interior T-37/70 GTO tribute/street and strip car. I have a couple engines that could find their way into the t37, a 455 with ported 16s and a roller cam, 462 w/solid cam and 96s was the last engine, eventually plan to do a turbocharger motor. I am guessing one of the those engines probably would find its ways into our 71 chevelle at some point if we ever have an issue with the 455 Olds in it. Chevelle was my first car. My cars are pretty much drivers quality type cars. My county road drive way and show cars do not mix very well.

I will just mention the cars in the shop right now (including the above T/A). My Dads 62 impala (red/white top), W engine 4 speed car. There is my old 11 second highschool ride, 69 Dodge Charger 510cid automatic (bright yellow), putting in a dynamic 9.5 4200 stall and rebuilding the tranny, and a 72 Satelite (white also highschool ride) road runner 440 getting body and paint, then lastly a 71 340 (curious yellow like the Charger) 4 speed duster that is getting a rotisserie type resto (my never ending project). T/A is ON TOP of work list for me, Charger is next on deck, followed by the impala (427 W engine will be next after T/A). I spear head the Pontiac stuff. Several projects going on at the same time. Got a hodgepodge of projects going right now. :) jay

Had some other stuff listed, thought it was getting to be to much info, your thread

What is the status of the 71 lemans sport? Going by the turbo 400 and the 12 bolt diff, someone must of had some aspirations of something bigger than the 350? Jay

'71 LEMANS SPORT This is my "long-term" project. It is slated to receive the 455 from the Grand Prix. I just acquired the pretty much complete (I hope) accessory drive brackets, etc. ( alt., p.s.., a.c. ) for this car. Also, the original 1971 Pontiac service manual and the Fisher Body shop manual. Both are in really good condition and have the drawings for the accessory drive system.Invaluable items, which I wish that I had when I bought the brackets! Just gathering parts that I will either want or need. I will probably be putting a pair of 6X-4 heads, that I already have, on the 455 once they are worked on. The TH400 should be ready to go. The guy told me that it was professionally built to withstand the abuse of drag racing. After he blew the healthy 455 that was in the car, he completely filled the trans case with fluid to prevent damage during storage. The rear-end is a non-chevy 12-bolt, equipped with 3.55 gears, which I think has a 10-bolt ring gear. I'll find out for sure once I get into it.

'79 T/A: Still trying to get to it. Once I pull the engine, I can identify just what I have and what damage was done to it. I'm thinking about a 400 stroked with either the RAM AIR III heads or the or 6X-4 heads that I already have. The goal id to have it running and driveable by the end of Summer. At that point, I can figure what repairs/ improvements I will do with it.

My wife's '77 Corvette also needs attention. Currently it is a "nice driver", but it too needs attention. One is to re-charge the a.c., which I have access to R-12 refrigerant and know an "old school" technician who is willing to give the entire system a "going over". And, God willing, a different engine and possibly an overdrive trans. is in it's future. I have 2 mid-80's 4-bolt main and one-piece rear main seal short-blocks. I would like to build one of them using the Edelbrock E-street head, relatively mild Lunati cam, Edelbrock intake and Q-jet carb, which are now on the car. Just a nice and fun car that will be able to get out of it's own way!

Man, I sound like you, Jay, with all of these projects! Good luck with yours, sounds like you have some seriously nice cars! Even though Mother Mopar made some nice cars, I tended to shy away from them, They had a bad reputation for their electrical "gremlins, but, I would take a '71 Demon, for sure! Those are some "bad ass" cars. Well, I guess that I've babbled long enough! Could use some input on things. Anyone have ideas on what rear-end is in the Lemans? Any other ideas or suggestions would be appreciated! Thanks everyone!

Lemans has a good start with those performance upgrades.

This is what we use in R12 a/c units.. It is a fill and go, cools better than r134a, but it gets to be expensive if you have to keep up with a leaky system. I have it in my 77 T/A. If the link does not work you can look it up, it it called freezone. My brother has a 76 Vette with a/c converted for 134a.
