318 build

Comp cams XE262, 218-224 @ .050 w/.462/.470 lift is about as high as I would go with an auto and 3.23's.
In the members resto section, I also am doing a 318, a '79 with stock heads and headers, 2-1/2 exhaust pipe, 3.21 sure grip equiped rear.
I choose the Crane split duration cam 272/284 (@.050 it's 218 -228 i think ) w/ .484/.480 lift. it's centerline is 2*s wider @ 112 vs. the comps 110. This should help keep the compression a little bit better.

Get the heads milled to achieve a 9.0-1 or slighty better ratio.
Better if you can bowl blend/pocket port the head.
