is 450 rwhp possible with these mods?
sorry about the question prob asked over and over but i want to know before i finalize the stuff i want to get. ok so lets say i have a 232/236 .587/.589 114+4 cam, stage 2 heads and ls6 intake. with a good tune on the average dyno what kind of power could i be looking at. its not a real big deal but im just curious. i would like to make about 450 at the wheels but i dont know if i could do that with this set up. should i go to a bigger intake like the ls2? maybe a bigger cam? stage 3 heads? what are your results with similar set ups? i have all the bolt ons, lt's, no cats, gmmg.

Assuming stock rear, it depends on the cam(how agressive the lobes are), the heads(what kind, 5.3,LS1,LS6, and compression). An electric water pump and 90mm LSX wouldn't hurt either. That should put you damn close assuming it's a good grind on the cam and good heads.
BTW, where are you in NC?

I would look into something better than your stock ported heads. 5.3's with a medium sized cam and about 11:1 compression would do you good, or some nice LS6 ported heads. As far as cams, I would get in touch with Allen at Futral Motorsports -->
and tell him your goals. He could probably guide you in the right direction on the heads that would work best with his cams.

Possible with that setup? Yes, but realistically 420-440rwhp is what you will see with good tuning. Personally I would not go with a cam that big unless you have a stronger rear with lower 4.10s for ex gearing. Stock 3.42s and that cam is gonna be a dog down low. You need 4.10s minimum IMO for that cam. Then if you would swap 4.10s into the 10 bolt at HC power level your rear is living on borrowed time. MHO

9" with big power is a GREAT idea for an m6 car.
oh yeh and 9" gets 4.11(12 bolts get 4.10)
and they dont rob thaaaaat much hp.. for the peace of mind , its worth it....
wanna make up the loss of hp? simply stand a 5500 rpm clutch dump on et streets and walk away from doughters at the tree
(i will say, they do weight alot ,i had to bentch press mine while my buddys bolted it up )

so what needs to be done to look at 450 then? i can get more to tune it and joe is puttin out big numbers with his cars up there cam only, so hopefully he can tweak mine to get some good power. i take it i need a 90 mm TB, maybe go bigger on the cam? what kinda heads should i shoot for at what CR?
one more thing, how much lift is OK? staying with the comp single springs it says .625 lift but i dont wanna push it and break one and i dont wanna have to replace springs a lot. waht lift shoudl i shoot for?
