Which Is Better For Drag Racing?

I JUST DONE A STOCK BORE 12.5 PISTON AND GT THUNDER CAM BUT I WANT MORE. I'M DEAD EVEN WITH A STOCK RAPTOR NOW IN THE 1/8TH. I'M THINKING ABOUT GOING TO A 416-440. WHICH IS BETTER OR SHOULD I GET A FCR AND HEADPIPE WITH RACE PORTING AND TRY THAT FIRST?:devil

have you gotten the CDI from MARCUMS?

A good race port and polish will help out a bunch,,a new carb wouldn't hurt either. I'd do those before boring it out since ya just put a new piston in,,,and the CDI might help ya some too,,helps me on the MX track.
Don't worry abou the headerpipe,,,I think the port and carb will really wake that beast up..

Just curious, where did you get you GT Thunder cam at? I'm looking into gettin me one. Price? Thanks bro!!

I GOT MY CAM FROM GT THUNDER FOR $160. GO TO THE LINKS PAGE UNDER GT THUNDER AND CALL THEM DIRECT. I FOUND THEM TO BE VERY HELPFULL. I TOLD THEM WHAT I HAD AND THAT I WANTED TO HANG WITH A STOCK RAPTOR AND THEY PUT ME DEAD ON THE MONEY. VERY GOOD CAM THAT PULLS EXTREMELY HARD IN THE UPPER RPM RANGE.

A carb will work wonders. And porting and a headpipe go hand in hand.
