Other than the basic bolt ons,for 500 reliable useable RWHP, you need either towing twins,or a big single,and some water to keep it cool of you plan on using the power a lot.If you do not keep it under 1500EGT ,you eventually will crack the head,and fatigue the valve springs/ruin the guides,and have a truck that smokes at idle and doesnt run its best.You can get by for a while,but it will only last so long at 1700-1800 EGT.
You can gamble here or go safe,but 500HP is a lot for the head gasket,ive seen them last 18 months at 500 hp with stock head bolts,ive seen them last 18 days,you are gambling here if you do not do head studds,and fresh gasket/have head checked for flatness.If it was mine id get it o ringed,and run ARP studds,and your done.Mine is going on 4 yrs with that setup with 67psi boost PDR twins.
you need a full trans with billet input shaft,and a billet flexplate for reliability. Still do not expect the trans to last forever,expect to need to rebuild again in 3-4 yrs maybe sooner if your abusive and drive alot.
To make the power,Id say a MITUSA fuel system,Don M mach 4s and Edge comp box is probably the most foolproof and least expensive way.
