LQ9 TBSS question? I know this is the V section but thought someone might have some insight on this build. Well yesterday some friends and I installed a built lq9 with 243 heads, longtubes, cai, performabuilt level 3 trans, not sure on exact cam specs but maybe in the low 230 duration range. He will be spraying a 150 shot on it. Sorry for lack of details but what kind of power do you think a built lq9 with medium cam, 243 heads and bolt ons will make on and off spray? Also vehicle is a TBSS.

Standard bore built iron 6.0 with listed mods should be in the 425-475 range just depending on details. With spray I'd say mid to upper 500's. That's iMo and I'm sure someone will dissagree that's just from my personal experiences.

Sent a rod through the block and he had the lq9 laying around. Lq9 is bored over not sure how much has forged bottom end. He says it should have mid 11 compression. He made 509whp on his old ls2 with intake, exhuast,(stock manifolds) ls7 cam, 150 shot. Also he will be spraying a 200 shot on the new motor.

Its RWD and he left the stock tbss manifold on. The only reason he left the 243s on is because its all he had lol but plans on swithing to l92s w/ls3 intake. Sounds really nasty but i guess any decent cam can do that. He should be getting it tuned in the next few days so i will tell yall how it goes. Also how do i go about uploading a video?
