Hey guys. I didn't know any better place to post this but I want your opinions before I dyno my truck. Someone asked me what my truck made for horsepower. I have no idea because we street-tuned it with no dyno. On a 1.89 60' it ran a 7.9 @ 89mph. The truck is full-weight with the exception of the spare being off the truck. I was guessing it's around 400-415rwhp. Are those realistic numbers? It has a SS3600 converter in a built 65e and 4.56's. Thanks for any input guys.

Edit- Also, I think with some Caltracs and a 1.6 60' it may touch a 7.5 or 7.6. I don't put much weight into dyno numbers after my old 2000 SS with a set of LT's (355rwhp) walked on a MS4 Camaro (415rwhp) from a roll a few times in a row. I just wanted to see what you guys think about my times against the average 6.0 trucks.

 

An otherwise stock LQ4 with a tune? 330rwhp. Pretty good times, though. The converter sure helps.

 

Milled 0.30" 243's and a 234/238 Advanced Inductions cam with a tbss intake and 92mm ptm tb.

 

Hmmm, maybe 370rwhp with that stuff. Have to spin it pretty high with that cam. What do you have for exhaust? Do you know the compression ratio?

 

Lt's/ory, e-cutout, dynomax bullet. I think the compression is around 10.3:1 but I'm not sure.

 

Anyone else have a guess?

 

i thought your motor was pulled and for sale? saw it on HPJ iv been thinking of milling and porting my heads as well. But my cam is a lot smaller than yours.

 

ive got a smaller cam then you and my 243 heads are milled .030 and there ported by AI its there 226 package i put down 415WRHP 395RWTQ and my trans was slipping tuner said it would have put down more

 

@ turbo4.8- I wanted to sell the truck but nobody even inquired about it so I decided to sell the motor and trans. After nobody wanted that and the ******** on hpj flamed my f/s thread I looked into just keeping it and going faster lol. There was one guy who wanted it for his tbss but after I told him it'd be a wiring nightmare I never heard back from him. I've been looking into suspension a lot and that's my next step.

@ twolow- I saw trucks with 430+ rwhp trapping 88-90mph so I thought I might be in that range. Thanks for the input.
