    Needed a cam for my application, knew what I needed, and this one is in stock, meeting every one of my needs. Comp Cams is a great company, and I have never had one of their cams to fail, as I always break them in as directed, and use the correct oil in the engine.

    I Don't know anything about thumper cams I do know I'd really like to freshen up the sound & performance of my 1995 F-250 351EFI stock engine with an RV cam or something a little more lumpy, I do carry a heavy slide in truck camper occasionally but would also just enjoy some performance feel & sound, what type of cam & lifter kit would you recommend for my stock 351 F-250? Thanks

    I Have a 69 Torino with stock 302, not planning on racing just looking for a mean sounding idle and good street performance. Headers, performer intake with 650 Holley are going on stock heads and ignition. This is a straight drive car. Is this cam compatible with my goal to be streetable with the nastiest idle I can get.

    What valve spring would be recommended? And any other things recommend to buy for better performance of the cam?

    I have a 1971 ford f100 with a swapped in 351w v8. The heads are bone stock. I converted it to HEI ignition, edelbrock performer rpm intake, Holley 750cfm double pumper carburetor, im still using stock exhaust manifolds with true dual exhaust with cherry bomb glass pack mufflers.. Now would this big thumpr cam/lifter set be a good match for my street-strip truck or would the regular comp cams thumpr cams setup for 2000rpm or 2200rpm be better?
