what other mods do you have?

I generally try to avoid used cams

That's what I'm gonna be running, i cant wait til its actually running so i can start giving my opinion about it. The B303 has good intake duration but I've read 5.0s usually do better with a dual pattern cam with a longer exhaust duration.

I would probably be more inclined to go with the Trickflow, but people still make good power with the B cam.

At the moment just what you see in my signature. I'm currently on a GT40 hunt and I'm going to get a Typhoon intake and other supporting mods as well.

If your on atight budget (arent we all) and canbuy a used B303 cheap ( $110.00 or less) then go for it, provided the cams in good working condition.The difference in performance between the TFS cam and the B 303 cam wont be that much different in your case. You can take the money you save and put it towards those GT 40 heads or some 1.7 roller rockers which should even up the cams alittle.

what you need to look at is the specs on your stock heads. they can barely support steeda and tfs. the fms cam is still under the limitations of the stock head. i had a previous thread where this was explained to me. if you got with the other cams you should replace head/ springs to allow for more lift. actually even with the b303 cam from fms you need to upgrade them but you can at least get away with stock for a while. i'll post it if i can find the thread

also i had a spec card that came with the cam from fms, it has a longer duration. the guy that did my engine said its more efficient than the other cams...he recomended it to me so i bought it...i love it so far
