I just received the above mentioned pan today, before I ordered I checked model fitment on Summit's site and it said it was compatible. After unwrapping everything I noticed the side of the box is labeled fits all Pontiac chassis.... except 70-74 firebird. Has anyone install one of these in a 70-74 bird? John
A little tweaking on the motor is fine, my concern was with the chassis statement on the box. I was worried about some difference in the sub-frame cradle area, but all the information I could find didn't show anything major in that area.
I plan on using the BOP pan gasket as well, just need to figure out if I want to go with the two piece or one piece viton rear seal.
I installed the two piece seal but it leaked. Comments on the pontiac sights are about 50/50 on success rate. I have not heard any negatives on the one piece. Im running the Teflon Graphite Rope with no leaks.
