cylinder heads swap

Good morning,

Please explain?

Big block for Buick is the 400, 430 and 455.

All the heads are different even with the 350 small block.

It's a Buick 350 I am told it's a big block or stroker motor.

Sorry, it is not. They were inaccurate. The 350 is a small block in the Buick line. the big block , as I stated, starts at the 400 and goes up to the 430 and the 455.

Roy

I just googled to confirm

Sorry, I grew up with these engines and rebuilt them and swapped them.

Irregardless , the heads will not work on any other engine. If you have this big block 350, you need the exact heads for that engine. Heads from any other engine will not fit.

Google is not the best information source for this. This is reality.

Roy

Pontiac, Oldsmobile and Buick had them but not GM they have the same block as the 400 440 etc.

Okay, sorry you disagree but you will get the same response if they know what they are talking about.

I am sorry you do not understand.

Roy

Sorry, you are too lazy to double check.

I am not lazy. I lived through those years and witnessed them first hand.

Hope you find your answer.

Roy
