Building a 461 stroker. Ported stock heads aluminum intake HFT cam 228/235 @ .050. lift is somewhere near 480/490 (can't remember exact lift). Engine is going in a 77 T/A with a Borg Warner 4spd and 308 rear. Mostly a street car but might see some track time. Goal is to be 400+up at the crank.
Which of these 2 carburetors is the better choice for my 461? Running pump gas and street manners are probably more important. Still want it to rip though.
I think that engineers do things for a reason.Virtually all factory high performance engines came with vac sec carbs.I drive a stick shift RA V tunnel port engine on the street with the factory Holley vac sec carb.For a race most or only engine I would do the double pumper.Tom
