I'm new to this forum and new to the L67 in general. I have an L67 that will be running stock heads with #105 springs, OER lifters, Double Timing Chain, ported and polished Gen3 M90, ported and polished lower intake manifold, Northstar 75mm throttle body, 180* T-Stat and SLP headers. I don't know what camshaft to use to get the most power. Any suggestions and advice would be greatly appreciated.
