what kind of rrs for my 93z28 lt1 will benefit me best. they have to be self aligning 3/8 stud 1.6 ratio.looking for a little performance gain. anybody use scorpion?let me know the ones you use and results. will eventually go hotcam or cc306.tell me the difference between crane,scorpion,pro comp.looking for best quality ones

 

go with pro mags. they can be gotten brand enw for about 280 and they are some of the best available. the narrow body clears the valve covers and they dont have problems with breaking rollers, grinding down on the stud seat, etc. the 306 or hotcam will like them for sure.

 

I'm running the 1.6 rockers in the hot cam kit right now but I have a set of promags waiting to go in, so thats my reccomentdation too

 

what are the part numbers on the pro mags, do I need to buy anything else like retainers,or new valve springs.

 

The part # for the 1.6 SA Promags for 3/8" studs is 1318-16.
Do a search for the rest of the parts you need , that topic has been covered alot before..
