1970 455, 4.195 bore, 4.25 stroke
6.8 rod, 10.25:1 compression Hand ported E heads that Dave Bishop machined for 2.20in 1.74ex valves flowed 322in 244ex Dave's old faithful 235-245 .636in .582ex 112lsa 110ilc 1.65 rockers intake, 1.5" exhaust Fully ported RPM intake manifold and 950 holley, dynoed with Dave at Richmond's in BC Peak was 20 numbers different compared to hooker 2" primary A body long tubes Also did a 459cid 9.7:1 all iron combo old faithful cam, Q jet, SD 265cnc 670 heads with D port RARE 2.5" outlet manifolds that one made 510hp 560tq Biggest difference between the short manifolds and the long tube headers is tq and hp below peak torque as you don't really have the scavenging effect that headers give, I imagine the long branch manifolds are possibly better but I have no testing with those
