In the old days I would have bought a cam from Ultradyne for it with numbers like this (IF exhaust was going to be upgraded but stock heads were kept))Ģ76/286 112. 050 lift.įor best performance install a camshaft with 110 degrees of LSA (lobe sep angle).ĭennis MooreI agree, cam is REAL small and I would be surprised if it made 300 hp especially with stock manifolds. The camshaft used in the 350/350 horsepower 1969 Corvette engine had 224/224 degrees of duration. You will need at least 218/224 degrees of duration lift to get close to 350 horsepower. The camshaft you chose is less powerfull/smaller than the stock marine camshaft. A lot of the cams I read about are at 114. Is it enough to get me to the 350+ hp mark and with a ls of 112 will this give me probs.
Stock omc exhaust (for now) with warmed over and smoothed runners and thru hulls. 050, lift 420/442 and a lobe seperation of 112. Weiend stealth air gap intake ( has roughed up runners for better fuel atomization) gasket matched with 2 inch spacer and a holley 600 spread bore carb with stub stack. backcut on valves, cleaned up runners, gasket matched and pinned studs. The engine has 9:1 compression 4 bolt stock bottom, (heads) 2.02/1.60 valves with 3 angle blended bowls unshrouded valves and a 30 deg.
The engine I am replacing it with was built by a local machine shop, I was told it would have a conservative 350+ 5000RPM) I was just wondering on your take on it. I am in the process of replacing the 350/260 engine in my scorpion 230.
