273 302 318 340 build

No sweat on the PS and manifolds. I'll do some reading up on it.
I have a set of X heads that were given a valve job years ago and havent been used since. Basically for the 340 I need gaskets. I have everything else (I think)
I checked out the 526AP and they are press fit pins as.
I agree with losing compression with the eyebrows and compression height. Im still searching for piston options.
I told machinist to hold off on 302 heads for now until I decide which route I take.
Thanks for Eagle link, it was a good read!
Ive no way to get the seperate weights on the rods (big vs small ends) only a total.
Set of good scales and a press at work but no "special" scales. So not sure bout the bobweight...yet.
Thanks!

I don't know enough on the manifold and PS..sorry. Look at Cempbell Enterprises too; they list the 526AP's still so must have some stock. The 285AP's will drop a gob of compression, with their lower compression height AND eyebrows.

Does the 340 come with heads? You don't want to try to use the 302 heads with the 340 block and pistons.... CR would be out of sight!
