Previous owner said just at 400RWHP and it's best run was 11.88 w/ a 1.66 60FT.. Sound about right to you guys with this setup? Any idea what amount of Crank HP that's at? people ask me all the time how much HP it has and some are too dumb to know what RWHP means lol.

I'm no genius when it comes to internal engine, but do the heads need to be touched to run a cam? Like ported or anything?
What are some other things I could do to get some more power?

(Wrong section, but) What are the gears and what's the size of the rear?

Thanks

A good set of heads will give you a few more ponies.

400 rwhp with a 224 cam only 3k stalled car seems a little high. I was guessing in the 380 range.

For small cams like that, nothing needs to be touched. 90% of the cams these sponsors sell are for stock untouched heads.

a good set of heads should get you another 20 - 30 horse. You could also get rid of the ls6 and get a FAST setup, although it's expensive. You could go with a bigger cam... Then there's the obvious power adders such as n20, blower, etc..

Car should have 3.42 on a 7.5 GM rear end.

He has an auto trans so that really should be a 3.23 gear if it hasn't been touched. Only m6 cars came with 3.42

My friend has the same cam with around the same setup you have but he had stg 2e heads from MTI in houston and he put 405 to the rear wheels with the torque converter unlocked so it would of put 410-415 if we had it locked. It runs 11.60 all day on motor.

well your car sounds like it runs strong man. but if you want some more power you could p&p your heads and like said before, that should net you about 20-30 rwhp. hows that stock rear end holdin up with that setup. u might want to look into gettin a 9" or a 12 bolt.

Rear end is fine, idk how I would tell if anything is wrong haha. Yeah the torque converter was locked during the dyno so maybe it is 400RWHP. About how much crank HP do you think that would be? and i'll definitely write down, Intake & heads ;D

I blew away a Saleen today, and I came off the stop light 3 or 4 seconds after he left haha.

when you break it. lol. im sure its fine now, but the 10 bolts are notorious for breaking. ive been lucky and out of the 4 f-body's ive owned, ive yet to break a rear end. im just sayin with your set up its more likely to happen. so just keep that in mind.
