I did some calculating on the compression increase I would get when I bolt my 66 289 2V heads on the 302 block I'm planning to swap the 289 block for.
If I did that right, the compression would be 12.5:1. No I was wondering if I can run a compression like that without getting into trouble. And if not, what is the best way to go, increase chamber size somehow, or go with reinforced components in the block (I figure the latter to be quite expensive). And how is the best/easiest way to decrease compression (I calculated when I do it by getting a thicker gasket I'd need a half inch thick gasket...).
Anyone experienced with this? The 302 block would be rebuilt and checked for cracks and all that.
Thanks,
Matthijs
