Default My combo

Just want opinions on if this sounds like a decent setup. LQ4 iron block, L92 heads gonna mill 0.30, Gmpp intake, accufab 90 tb, aarons elbow,Futral 228/236 600 intake, 630 exhaust 112lsa. Maybe a little spray, Does this sound like it might make decent power? I have long tubes and true duals also.

That sounds good. Just make sure you check piston clearance. That is alot of lift for milled heads with huge valves. Those are great heads though. A bigger cam wouldn't hurt if not a DD.

I would say over 425 RWHP before nitrous. I guess you would have to rotate the engine with the heads on it. But they do make pistons with valve spots cut out. I went with the T-rex which is .615" lift, and they told me to make sure to check PTV if using modified heads. And LS1 valves are just over 2.00". L92' are 2.125.

I'm hoping for some good power! I'll keep everyone posted
