Best clutch KIT

gonna be a 416 hopefully making 450 to 500 hp street , strip car with slicks , ive heard mcleod what do you guys think would be best choice:D
I dont know who got the best clutch kit but this one from SPEC is very affordable, with a great quality, made by a very reputable Company right here in the USA.

Look for the SD044 Kit if 10.5 and 23 spline is what u need!
