I’m freshening up my conventional headed blown alcohol bbc and thinking of trying a cam with more duration and possibly a slightly wider LSA, I’m currently running a cam with duration of 280@.050 int. And 290 exh.with an LSA of 114 and lift of .819” int. .811 exh. With cyl. Head flow int. 440 cfm@ .850” exh 335@.850” on a 555 CI with 11/1CR and a very good HH 14/71 retro blower @ 38% I’ve seen 43lbs @ 8000 RPM. I’m thinking of adding 10 degrees duratioOn the intake and 15-20 on the exhaust and spreading the LSA out to 116 and probably leaving the lift where it’s at? The motor makes great power but I think adding more duration especially on the exhaust will help? And spreading out the LSA will help from blower more boost out of the exhaust ??? Any opinions will be greatly appreciated , thanks for your input!
