New Shortblock is a .080 over 261. Bowl ported 848 head with custom 2.02 intakes and 1.50 exhausts 78 cc' s chambers. 7.00" gmc 302 rods. Dema Elgin cam .472 lift 232deg at .050 solid lifters. Around 9.2 to 1 compression. After reading the flow bench tests on Inliners I'm going to remove the bulge in the combustion chamber by the exhaust valve. Should give me some more pep than my 235 and still be pump gas friendly!
