i know that it varies greatly on many factors but i jst want a round park estimate on the HP my tahoe might have since i cnt get it to a dyno anytime soon its a 2000 lm7 with 140k miles it has obx lt headers with ORY, corvette servo, CAI and im waiting for my BB tune to get here its a 91 octane. with the tune and my current mods how much hp you think it has? to the wheels. will be adding a stall nnbs/tbss intake and 4.10 gears in the future

 

250ish

 

^^^^ Maybe after the tune..

 

aright cool, now my goal for this truck would be at at 330. ive been looking around at cams and saw that an ls6 cam is a good budget cam will that work? also is there any other budget stock heads that will work better than the current ones im a college student at the moment which is why im trying to build this slowly with the best deals i can

 

799-243 heads are the next step up. Possibly have them milled some to up compression( prob 100ish$) at a shop. The LS6 cam is cheap, will help bump the hp. But for another 110$ or so you could by a off the shelf aftermarket cam, but keep in mind alot of them require a bigger converter. I wouldn't run a cam with a duration any more then 212 on a stock converter. If your looking for that power, you better start saving for at the min a trans cooler, good shift kit.

 

I would do a different cam for a 'hoe. I don't recall that it really hit until 3800 or so in my stock ZO6 Vette.

 

ahh yes thats also what i left out a trans cooler and i will be doing a tb stall will that help it out? this is also a DD which is why i dnt want to put in such a big cam or stall just enough to have some fun with it

 

I would go 212/218 its a proven no stall cam. You will make plenty of low end torque with some screaming up top power. With a tb stall it will be that much better.

 

im still trying to figure out how to read cam specs jaja but i have been told alot that a 212/218 cam would work great..would that cam require new valve springs and push rods?

 

Any time your going with a more aggressive cam its a good idea to do the springs and rods. LS6 springs and some used PR's would work fine.
