The most notable difference is that the ponitac exhaust port flange extends 
out past the outer edge of the valve covers by 1.5". There is no easy way 
to tell the difference between a 350, 400 or 455 pontiac that i know of. 
But I'm not an expert on Poncho engines.

Hi

I know this aint strictly efi but you will know the answers, as it
concerns an American vehicle and I am from the UK..

I have a 1976 Pontiac Firebird with a 350 CI engine, is this engine GM
or Chevy?

How can  you tell the difference between the two engines, I was told
Pontiac used Chevy engines in some Firebirds but when or in what models
I dont know.

Is there also any obvious differences between the 350, 400 & 450! ?.
