Well you'll need to build it then to handle the full 600 (figured hp)

So, youre looking at full forged bottom end, stronger main caps , and put together with alot of attention to detail.

For oiling a HV is uneccesary, but constant even flow (reliably) is. So get a NEW High quality oil pump a good (deeper) pan (hold more oil, and keep it away from the reciprocating assembly).

An eagle forged crank, eagle Hs or some scat Hs should hold up to your goals, as for pistons, I'm partial to JE/SRPs. I would go 5.7 rod for insurance to keep the crown thick on the piston.

With alot of nitrous excessive compression isnt a must for power (static) so I would shoot for 10.5 to 11:1 to spray 200 shot on and keep it simple.

Do not skimp on the prep and assembly.

With a 200 shot you should use nitrous pistons and heavy duty pins. Nice thing about that is it give you the option to set up the engine to what ever spec you want not what the kits come as from a catalog.

I'm working with Erik @ Horse Power Engineering (HPE) for a very similar build.

Fully forged with nitrous pistons, heavy duty pins and fully assembled shortblock in the $3400 range after shipping but I'll be sending my core back also.
