What should i look at doing as far as whats a good upgraded intake, ( can i go LS6?), whats a good heads and cam? - looking for 500ish hp n/a, and the nitrous will make up the torque.. lol

Longtubes, full exhaust, Air-lid, stall, gears, suspension of course, and as far as a heads and cam package goes... check out texas speed and performance.... (www.texas-speed.com) Alot of guys go with the prc stage 2.5 5.3L heads and the Magic Stick 3 cam so they won't have to flycut the pistons. You'll have to flycut if you go with the MS4 or bigger. Last but not least a Good Tune will always help
One of the most common combo's is the prc 5.3 heads and ms3 cam. Simply b/c it has proven to be a good setup at a budget price... Not to mention the sales reps are awesome to deal with. A+++ for TSP!
Patriot Heads are also a nice budget setup... just check around and LMK what your wanting to do with the car... Oh and check out the newbie thread in the ls1 department. LOTS of help there.
Hit me up man and we can setup a game plan for your car... I'm still learning, but in the past 6 months I've learned ALOT...

TTYL Jeff!

I've been thinking about trick flows 515hp h/c kit as well..

1987firechicken

Sounds like you have you mind made up already jeff you been talking about that trickflow heads setup since before you got the car. If I had enough money to do it right and do it once I'd pick up a set of trick flow or AFR heads, have patrick G custom spec a cam (he built a 500 hp NA car), and the 92 MM FAST intake. Thats about 4 1/2 K though. 500 HP on an auto, stalled, all motor car is gonna be a tall order and suck to drive around on the street even the mighty LS1 can't do that smoothly. You'll need a hellava tune to keep it from surging and a set of gears like on your last car. 500HP on the sauce will be pretty easy though and you don't need those expensive *** heads.

For me, my broke *** can only afford the Texas Speed setup which will still run very well and I won't have to cut off a nut and sell it to finance it. 5.3 stage 2.5 heads and a tourquer V3 or Futral f14 cam is what i'm going with and that SHOULD net me about 410 - 440 at the wheels and be drivable and make some good torque for street driving I do. You seem to want another drag car so do what you will just my 2 cents.

Very good advice Alex... You must have been thinking about what to say for a while huh!

Let Heck and I know what direction you want to go with. We do a lot of business with Gunnar at Patriot. I personally have bought about 3 sets of head off him in the last 6 months.

Well, i usually do all my own work, but i am interested on pricing a good top end setup including rockers, springs, pushrods and stuff.. I know 500rwhp is going to be tough through the auto.. lol.. i remember all the crap i had to to to my LT1 car through the 6 speed..

Alex is trying to ruin my hopes and dreams. :p

& Justin, i think i've seen that car out somewhere before and not just sitting in your shop covered in dust :p

Thats the beauty of an LS1, you don't need all the **** you had to have for an LT1.

Stock rockers will be fine, and most of the top end stuff is coming way down in price. If you buy the heads assembled, you can usually pick the springs you want, and push rods are like $60 bucks now.

Dave has a really good relationship with Rodney at RPM transmissions also. They build the BEST trannys and have, out of this world, customer service.

was just browsing- found this cam kit from Patriot- what do you think about the cam?

I think im going to go ahead with the trick flow heads ( once i get some $ established) but i want to pick the right cam & valvetrain package.. Oh, i'd also like to spray her with a 125-150wet shot to make high 500's hopefully?

LOL jeff at the 500 hp off of a 225/229 .581"/.591" 114 lsa cam.

Jesus jeff look at the recipe for the 500 rwhp sticky in the internal section.

"Camshaft selection:

While this can be a black art, there are some consistencies with 500 rwhp cams out there. Most have between 235-240 degrees of duration on the intake and most have between 240-244 degrees of duration on the exhaust. Lift is important in that you want to get as much in early as possible. Fast ramps work great on the intake lobes. The Comp XE-R lobes are very fast off the seat and will put the lift in the .600" range. They're pretty aggressive in duration at .200, but there are others that are faster. The new Comp XFI lobes and LSK lobes put even more duration at .200" than the XE-R lobes and have more lift. If your head flow does not fall off above .600", then it makes sense to run the higher lift lobes. Not because of the airflow gains above .600" as much as the greater valve curtain area they provide below .600". Because my AFR 205s stalled above .600", we chose to run the Comp XE-R lobes in this 500 rwhp build."


Sooooo that cam you posted will be a very good street cam that will make torque everywhere and your power band will start nice an low and make power under the curve. But if your looking for 500 at the wheels your looking at a much bigger cam. I think you need to get what you want straight, then read, then read again, then read again then buy your parts. Research never hurt anything or anyone. Your looking at alot of money on parts since your gonna want new lifters, gaskets, timing chain, pushrods, springs, cam, and a set of heads, put an oil pump on your list too since it's a 99. Plus a tune and maybe valves and seals if they don't come on those heads and your looking at serious bucks man don't put in a cam that you'll be wanting to pull out in a month. I research the **** out of everything I do to my car before spending a dollar bc I'm cheap and I want it to run right and be efficent.

1987firechicken

It's gonna be alot of ******* money jeff to build a 500 rwhp all motor car. Keep in mind your looking at a premium exhaust too IE QTP or Kooks headers, a custom Y pipe or true duals, lid, a 92 mm FAST intake and throttle body. I hope you got about 6K laying around for this project bc I sure don't. Add in the stall, gears, and the tranny your gonna have to get built and a 12 bolt and full suspension and your ******* toast for money but that ****** will run it's ***** off spraying. Calling it a street car will be a stretch with all that ****.

Or you could go a little more mild with your setup and spray it more and keep your tranny and pray the 10 bolt holds. I'm gonna build up the rest of my car and make sure I have a daily driver on back up before I do crazy **** and bend up my body and make **** blow up.

This combo for the win! I plan to put the 2.5 5.3 heads on my car along with a 90/90 hopefully this winter

Thanks Jeff for chiming in man...

And Jeff (indirocz28) if you have any questions about how well the ms3 runs on the street just ask Jeff- (sedanman) and John- (Ls1Leadfoot) I'm sure they would be more than happy to let you ride in their cars to see how it drives on the street and answer any questions you might have. Both guys are very cool.

Oh and Alex is onto something with his statements he made in the above posts... If you want 500rwhp N/A, GL it's harder than you think man. Honest!

Just research and check out alot of threads to see what other people are doing and what performance shops are doing as well. Thats where you'll find the most help (Performance shops) since they can dyno before and after to see how a mod will benefit you or hurt you.

500 HP N/A is a max effort motor that is going to be runnin on the ragged edge out of a 346. I would settle for a 450-475HP on motor and just shoot up with some juice to hit 600HP.

As for a cam for the LS1-

I think im still going to go with Trick Flow heads
and have Comp Cams make me a custom grind for my LS1 going off my cam spec's i had in my LT1

230/236@.050 Duration .555/.580@112LSA Figured on a 1.5 ratio rocker.(however, if i convert the lift from the 1.5 ratio to the 1.7 of the LS1 the exhaust comes to like .697 - so i really dont think that is gonna work haha.. I'll have to get the lift spec'ed straight for the 1.7's...

I think that should be a pretty nasty yet very streetable cam along with Trick Flow heads, supporting springs, lifters & pushrods, LS6 or FAST intake, throttle body, ported MAF,36/42lb injectors, Pacesetter LT's & ORY,magnaflow Catback, SLP lid,125 shot and a 3200 stall??

Opinions please anyone who OWNS an LS1....
