I run a 90mm acufab on a supervic and it runs great
I have the tune a bit fat if anything

 

i have the same heads as you ported by ai and would like to get those numbers but with the hydrolic rollers can you suggest me a cam thats still streetable and could probly get me in the 10's. is it the ls1 kind or the mustang kind and Does everything hook rite up to teh accufab or is there some modifaction needed?

 

I would suggest looking into the 860performance elbows that nitrous outlet sells. They will take a factory style TB which makes install much easier. Do a google search, it'll come up.
