does anyone have 243 vs 862 charts?
i have been wondering how would this do on my truck. ported and polished my 862 heads along with the combustion chambers and have a 3 angle valve job. vs. 243 with the same work. just wondering how it would flow and if some or any hp/tq would be gained or lost. and upgrade Intake valves to 2" and Exhaust Valves 1.55"
