Re: Anyone ever use this cam? (gregfloyd)
Don't know what you have done to your car so far so.. That cam looks way to big to be running on a car that is stock. With that cam you need to do alot of other things to your engine befor you throw that type of camshaft in.Ex- stall converter, at least port+pollish heads/intake, bigger throtle body, biggger valve springs. But you have to thingk about is that ev\en ported cylinder heads and intake wont flow enough air for that cam to reach its full potential. Stock tpi intakes powerband dropes after alittle over5k rpm, so a cam that has a powerband that goes up to 6k+ is worthless for you. Order the tpis handbook at http://www.tpis.com and find a cam in there that will work for you or they will segest one over the phone. Hope this rambling helped a bit :party:
