Will this cam work okay?
After to talking with some people in the drag race forum, I was wondering if I maybe should swap out my cam. I pulled the 305 yesterday and I would like to figure this out before I put the 406 in. This is my setup right now:
406
650 cfm Holley VS carb
Chevy aluminum intake
882 heads (yes I know they are crap but new heads are $$$)
flat top pistons, 5.565" rods, stock crank
RV cam
Hedman 1 5/8" headers with 2.5" dual turbo mufflers and cutouts
I have a Comp Cams Magnum grind 280H cam (280 adv./230 @ .050", .480" lift) I know it does not match the setup as well as the RV cam does but I don't think I will be able to hook up all the torque with the RV cam plus it will drop off about 4500 or so rpms. I know better than to use Desktop Dyno to get real power numbers, but I have heard it is good for getting a good idea of the power curve and the 280H moves the torque peak up 1000 rpms and the hp peak up 500 rpms. Will it be a good idea to swap out this cam? Will the cam fit without hitting the rods? How difficult would it be to change out the valvesprings, and would there be a way to see if I need to (i.e. part number on them, way to check lift limits, etc.)?
Thanks,
Adam
