Help me guesstimate my hp/tq
 

Sorry if this is in the wrong forum. I really want to get an idea of how much power my swap is going to put down, because I probably won't be able to take it to a dyno until March or so. I just got the thing running last month and it would kill me if I didn't have a CLUE what kind of power it is making until spring. Can someone give me an EDUCATED estimate of what they think it will do?

Drivetrain specs:

6.0 iron block 10.6:1 CR
317 casting heads, slightly milled, no porting
LS6 intake
42# injectors
Mahle forged pistons/Eagle forged rods
MS4
Scorpion 1.7 rockers/PRC dual valve springs
Melling race pump
25% underdrive balancer pulley
T56 rear end gears are 3.42
Longtubes (1 3/4 primaries, 3" collectors, should have a 3" ypipe dumped into a bullet before the axle)
stock LQ4 throttle body
Z06 MAF


I'm not sure how much of the above info is relevant, figured I would put everything up there. Does anyone have a clue what this thing should do? The machine shop seemed to think somewhere around 450hp-ish.

410-430 rwhp and 400-410 rwtq as long as you don't get valve float.

Valve float?

I agree with Nitroused383. Running unported 317 heads with that big of a cam will be your biggest restriction on your setup although it will like the added compression. Ill say 440hp/410tq

A lot of guys have problems with roller rockers as they are heavier at the valve tip. The stockers are great until you get real serious.

i say 425 hp an 407 tq....

what´s the cam spec´s?_

I am going off memory here, its on Texas Speed's site though, just can't view it on my phone. I think it is 239/242 649/632 111 LSA... I'm sure that's not 100 percent correct though.

440/415
