318 build with XE268 AND 302 heads

megavites said

so long story short...I came upon a free 318 block with heads today. I'm going to take and rebuild these low compression heads and go with the Whiplash cam.
Over the winter, I'm going to rebuild this 1970 block with KB167 pistons and the 302 heads. Now its just a matter of
picking the right stick to run in this high compression SB. I'm guessing 10:1 comp.
What would be your choice of cam at that point? TC stall will match and rear will be 3.55.

Now you're talking LOL! What are you going to be using the engine and car for?Cam selection (and actually ALL engine build parameters) flow from that.

BTW, you're Static CR will be around 9.5 with STOCK deck height, KB167's, 64 cc combustion chambers, and the Mr Gasket 1121 G head gaskets. Quench gap would be .040" + or - with that; the variations would be due to piston-to-deck variations.
The above post refers to 'zero decked' pistons to get to around 10:1, but then you cannot run the 1121 G head gaskets unless you are very brave and control the piston to deck height very tightly. That brave setup would get you to around 9.8 with the 64 cc chambers.
The next step up in reasonably priced gasket thickness would be a Felpro 1008 .039", and with zero decked pistons, SCR would then be around 9.5. So if you want to hit that 10.0 SCR mark with those gaskets, then you'll need to get the combustion chamber volume down to around 60 cc's with some head milling.

But again, it all goes back to the application and your plans for the engine/car.
