If I went from an f-cam to a b-cam would it be a big differance in th low end. Right noe of the line the car feels sluggish, but once your up in it it pulls like crazy. The probly is I wanted a very snappy off the line car, so I am thinking about putting a b-cam in it. What do you guys think.

I think a B cam would make it worse off the line, but I'd have to check the cam specs again. What RPMs are you talkin bout here?

The f seems to make power starting at like 3,500.

Isn't the F-cam for F/I applications?

Some people consider low end 1500rpm and some consider it 3000rpm...

I'm gonna say the B cam makes power higher than the F. The b cam has a lot less lift and duration, people usually say the E cam for street and the B cam for strip powerwise... and the F is a step up from the E. I dont think the B cam will give you what ur lookin for.

Edit, with that 4.10 gear ud prolly want a higher RPM cam anyhow

This is from the FRPP website:
------Peak RPM
-------TQ BHP
E303 2500 5500
F303 2800 6000
B303 3300 5100

So judging by that, if you want to stick with the alphabet cams the E303 would be your best bet.

Yeah those are gone now its 3.73's. maybe an e than I am not sure. But I have to do something aboutthis low end.
