For what you're wanting I would go with a Borg S366/91. JMO.

 

i kinda thought about that but i was trying to think what would be good later down the road if i upgrade internals

ugh so many options

 

if you only going for 700 hp down the road , i dont know why you would upgrade the internals this isnt a honda motor lol, that motor will take that fine as long as you have somebody tune it that knows what they are doing.only thing i would say at 700 is head studs and that only if your really bringing the timing on heavy.

 

i was meaning better flowing heads, cam, valve train. I know bottom end is fine if the tuning is good

im pretty set on the 472/83/.90, seems to be my best choice in the price range. Good thing is if i dont like it that is a very common used turbo on duramax so it would be easy for me to sell

 

sweet , get it ordered already! then bring it down to B-town this summer so i can check it out.

 

I plan on hitting at least 1 firebird race, and goto mexico for the night lol.
