Buying the internals will be who ever is running a special.Sometimes SHM has a set of pistons,rods,bearings for 1150.ModMax is pretty good for the price also.It depends on how much power you are going to go with but the Reg. 99up crank is good for alot of power.I havent seen anyone break one yet.The cobra crank is forged but I have yet too see it worth the money they want for it unless your going for 99rwhp and 7500rpms then you might need it but there alot of people running in the 700rwhp range abd still have the Reg. GT crank just thought I would let you know it could save you some big money.Just make sure you get ARP bolts for the rods,and the heads those are the most important part of these motors I think.The Rod bolts on these motor suck and usually give way with power.
If you want some cams I have a Set from Keith at FOMPK dont know what it stand fro but they are 558/228/114 and he said they give 30-40rwhp on Juiced cars.I also have New springs that are from him.Let me know if you are interested?PM me!!
