![]() ![]() The test vehicle was a 1995 Chevy Impala SS with 3. ![]() This photo reminds me how shit my rear bumper is. so you think a 350 would outperform a 383 with about the same money into it No way - same heads, same cam, but just the larger/heavier rotating assembly - the stroker will murder the 350. Not sure if this gives an idea of the fitment and width of the rims but they look fat! I've re-purposed the exhaust side studs (which I replaced for titanium studs) on the intake side so they will be all studs instead of bolts.Ī few little issues to work through but we're getting there slowly. A bit disappointingly the manifold flange is warped so I'll need to get it machined which is a pain. The 65-67 L79 350 hp cam and the 68 L79 350 hp cam are shown the same in some. I threw another coat over the top cover as well as it had a few chips from bouncing around the shed for the last 7 years.įit up a few bits and pieces (thermostat housing, A/C bracket, timing belt, etc) and then trial fit the intake just to see how it looks and work out what else I'll need to modify. Xtreme Energy 242/248 Solid Roller Cam for Chevrolet Big Block 396-454. The long block was sound so all it needed was a decent cam to awaken this engine’s potential power. Recommended loads for a flat tappet big block Chevy cam during break-in would be closer to 100-110 pounds of seat load with a. This combined load probably contributed to three of the cam lobes going flat. This creates almost 350 pounds of load on the lifter at maximum lift. I'll put at least one more coat on before I fit it. This engine started life with a good solid foundation of SRP forged 10.25:1 pistons topped with a pair of factory iron oval port heads and a dated solid lifter flat tappet cam. Compounding the issue is the cam’s 0.520 inch intake and exhaust lift. Put the first coat of wrinkle finish paint on the newly extended lower timing belt cover. ![]()
