The Pontiac block outside dimensions are all the same for all displacements,
You can tell what size Pontiac engine you
Have by looking under the car on the driver side. On the side  of the block
will be cast 350 or 400 or 455, you might have
To scrape the junk off the block to see the numbers.  Take a lot at

	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! ?.
