and lookin on the dyno list... im the highest n/a 4.8 now and i only gotta get to 352 to beat a 4.8 with an sts kit...

 

BlackGMC is at 303hp/300tq with his 4.8 with a 222/224 cam.

44 more hp is gonna be hard to reach N/A, the only thing you have left to do is heads.

 

Those numbers were with the old cam cheif , hopefully gonna go to the dyno next week

 

You might lose tq like him with that bigger cam

I'm gonna guess 315hp 320 tq out of the new cam

 

heads... pulleys... intake manifold... throttle body... better intake... better exhaust setup... theres plenty i can do... but still 44 hp shouldnt be hard to accomplish..

 

a good set of heads will jump you that much by themselves. http://www.texas-speed.com/shop/item...id=84&catid=40

the heads, same cam, and e-cut out will beat your goal, IMO. i would say 355-360 with good heads and exhaust opened up.

if mine hadnt blown i would have known for sure.. it made 300+/300+ n/a and 400+ on a dry shot.

 

heads/intake will be a nice gainer... I think its possible fo shiz

 

LS6 intake wont gain you anything, TB will be minimal, UD pulleys might get you 5-10, CAI wont give you anything really. Id say with heads itll be close

 

honestly, i would rather have higher torque down low with a 4.8, and a good size stall (3200+) to get it moving.. that cam choice put you a bit low on the tq... but a good stall will compensate, and some 3.73+ gearing.

heads will jump your tq number equally though, and you will have a high 12 n/a capable machine.

i think a 4.8 with 4.11 gears, 3600 stall, and 350 n/a rwhp can do a 12 sec 1/4 ... traction pending. that WAS my goal, but mine popped early in the testing procedure
