Settle something for me...390 vs 400.

One of my first cars was a 1970 Pontiac Firebird Formula 400. Small block 400, Muncie M22 Rock Crusher trans, 4.11 gears. That thing would still chirp shifting into 4th gear. No smog, no ac, no nothing. Just motor, dual snorkel air cleaner assembly with boots on the snorkel that sealed to two long hood scoops. Had to clean the air cleaner all the time, bugs, leaves, etc.

i have nothing to add. i have only driven a 70 something lincoln towncar with a 460, the old company 80s f250s with the 351, and my old 65 mustang with the 68 302 in it.

Wrong kind of 400...

I know. But I felt since the discussion was on 60s and 70s, motors, that is was barely on subject. At the time, I also had a 78 Trans Am with a 455. The 70 with the 400 was much more bad-ass than that clunker 455.

my step mom had a trans-am with the 455 also. it was a smokey and the bandit ta. i was still in elementary school so this was mid 80s. i know the back seat sucks for 3 kids to sit in because someone is sitting in the middle which is not a seat.
