Chevrolet V-8 Engine Specs

[hurst01]

I was just looking through the forum and thought someone might want some engine specs from Chevrolet V-8 engines. Hope this helps someone.

I went through a lot of effort to line all of this up so as to make it easier to read and when I posted it, it crammed it all together. I hope someone can get some use out of it.

This topic is now a sticky. Thanks, Ed!

Hey Ed,
Thanks for posting the engine info!!
I have already used it a number of times!!
I understand the frustration on formatting data and organizing it, then sending or posting only to have it scrambled into a hodge-podge!
Thanks,
Ray

I've reformatted Ed's post, and the data should now appear in the correct columns. Better late than never.

I've committed this to memory so I don't have to look it up.

Im in the process of building a 334 right now, just waiting for the capscrew rods to arrive.
Potentially the 334 could be a super efficient engine as the bore and stroke are near ideal thermal dynamically.
I'm using GM's amazing TBI swirl port 187 castings.
