Its a balanced lightweight bottom ended 383. The heads are ProComp 215cc Fully CNC heads. I bought them on Ebay bare. I installed my own titanium gear in them. The cam is a Luntai solid roller. I dont have the exact specs with me, but something like 305 dur, split .650's lift with 2* advancement to barely miss the pistons. It also has a Rev kit, matched Victor Jr intake, 950 Race Demon carb, 1 3/4 - 1 7/8 step headers, MSD ign, Aermotive Fuel system, N2O, etc. The car is getting closer to completion. Just havent had time for it in a while.
