Does anyone know if the intakes for 1969 firebird V8's were all the same for the 2bbl 350 - 4bbl 350 H.O. and 4bbl 400 - I'm upgrading my stock 69 2bbl 350 with a set of # 16 heads, carb, and cam. I was going to do the intake as well but I’ve been told that Pontiac used the same intakes on 350’s & 400’s V8's in 1969 except for Ram Air T/A so there really is no need to upgrade the intake on my particular project, is this information correct??
Not quite. A 2 bbl intake is obviously different than a 4 bbl intake. But casting 9794234 was the common 1969 4 bbl intake casting for all but Ram Air IV and V.

All Pontiac engines except the 301 are the same on the outside and have good interchangability. The main difference between a 350 and a 400 is the bore size. Smaller details determined compression ratio and rated output (cam specs, valve size, etc.).
