Decided to start new thread since it's more cam than crank related.
M20 with 885 head with OEM size valves and new oem valve springs, 2.9L strocker (84mm cam with 85mm IE/Mahle pistons), Megasquirt, stock intake manifold for now.
I'm considering a few cams:
1. DBilas 284 - 11.5mm valve lit, larger than Schrick 284/272 or 288, will new oem springs survive?
2. Dbilas 276, 11.5mm valve lift - the same concern as above
3.Shrick 284/272 - 11.4/11 valve lift. Supposedly ok with oem springs but don't think I need dual pattern since my CR will be 10:1
4. IE 284°/280 11/10.7mm valve lift - I guess this is a cam IE/Mahle designed those pistons for.
Any thoughts
