Why is it so hard to get good advice !!???

When you look at cam specs most people look at duration and lift and rpm power range and that's what mail order catalogs show also.... Those cams listed for "440's" are for 440s ... With a stroker engine bring that power range down a few hunded on both sides... Big cubes eats up duration. I left that xr286r comp roller in across ported 906s to MW ported Indy EZs... Probably to large to to small :D

My cam right now in the dart is a 283/292 duration on pump gas.
