`Patrick` If i reground the cam wouldnt that make the lift lower then what it is and change my duration. I thought the magnum cam was all around low everything to begin with.
they reduce the base circle to increase the lift/duration. my stock cam (LA roller 318) was ~ 240 adv/180 .050 and ~.260 lobe lift. bullet cams was able to fit a 259 adv, [Email]208@.050[/Email], and .316" lift lobe on my cam core. there is a limit of how much lift/duration they can fit on a regrind, it's mainly limited by the base diameter of the cam, and how deep the hardening on the lobe is. the guy at bullet said that the chrysler cores are among the deepest hardened, usually ~ .4" deep. for a stock pistoned 360 with the heads you've listed, I'd probably see if they can fit their HR272/340 lobe on that cam core....if not maybe the HR266/325 or HR272/320 or HR274/325....
call bullet cams (website is http://bulletcams.com/Masters/HRlobes.htm) I dealt with Tim there. good guy, went all out to make sure I'm satisfied, and I'm very happy with the way my 318 hauls around my porky 5th ave. it has as much power as my old LA 360 with an XE262
