Years ago I installed an old Comp 280H cam in a daily driver because I had acquired it with a bunch of parts cheap, now I'd like to gain a touch of power for an index street class, I now have a Mopar .484 I've never used, kinda like to keep it hydraulic for now, I have others but all solids and would need to change valve springs for them. Car will do the 7.50 index in good air but doubt it will in lousy air...
