Hey all just picked up my 2000 Blue Green Chameleon Formula. This will be my first venture into Fbodies. Not my first time modding cars; however, I'm coming from mainly modifying Mustangs. I had a 2009 G8 GT, but sold it before I really got to tear into it any. The last mustang I had was a 2014 5.0. Ran 7.3@96 in the 1/8th with Boss IM, full exhaust, 3700 stall, gears, and E85. That is my goal the I would like to shoot for in the new Formula. I'd like to get as close as I can before eventually spraying the car. My end goal would be to hit below 7.0 in the 1/8th when all is said and done.

The car is a M6 car so I know it will be more difficult to get to my goal than with an auto, but all my previous cars that Iv raced (besides the 2014)have been manuals so I'm not new to that. The car currently has the following mods.

Moser 9' rear
35 spline axles
Wavetrack diff with 4:10 gears
Spohn tubular body mount torque arm w/ driveshaft loop crossmember
Umi tubular LCAs
Umi non adjustable tubular PHB
Umi weld in sub frame connectors
Koni yellows all four corners
Solid motor/trans mounts
Zr1 replica wheels 17x9 17x11 315 nitto nt05rs on the back
Texas speed 1 7/8 long tubes
Off-road Y with moroso spiral flow race muffler dumped
Texas speed 220R cam
Texas speed hardened pushrods
Melling high pressure oil pump
ls6 intake
SLP lid/filter
Monster stage 2 clutch/lightweight flywheel
Mgw shifter

The car is currently at the shop getting true duals with an x pipe ran out the back. I think I'm going to go ahead and order a heads/cam. Right now I'm looking really hard at the patriot promax 64cc stage 2 ls6 heads, and a VRX5 236/238 .601/.605 112+3. Does this sound like a good combo to you guys? If not recommendations? Also I'm thinking with that combo the Ls6 manifold won't be enough. I'm trying to decide if I want to go with a fast 92/92 set up, or go with a 4 barrel efi intake with elbow. I would love some input on this from you guys as well. Keep in mind I will eventually be spraying this setup, 100-150 shot more than likely. Also any other recommendations, or suggestions would be greatly appreciated.

Oh almost forgot I will be getting some skinnies for the front, and some 15x10 for the back and will be running a 27-28" radial/slick.

Thanks everyone!

 

I didn't think Patriot was even in business anymore. Even if you can still get those heads Patriot was kind of a bottom of the barrel company. If your looking for a good budget head you may want to look at PRC's 225 as cast heads. That cam looks pretty good but this car sounds like a weekend toy/ track car, if thats the case I'd go with something like Tick Performance's Polluter V2 239/244 .62x/.59x 112+3 or BTR's stage IV cam 235/242 .621"/.592" 111+3. They are Max effort cams and maybe a little to aggressive if you want to do a lot of street driving, but with a really good tune they shouldn't be to bad for something that only gets driven for fun. I'd pick those cams over other cams like them like the MS4 because they use less aggressive lobes that don't beat up your valvetrain components.

In the end the best thing you can do is spend as much time as you can researching everything before you buy anything, and call/email the vendors on here to get there professional opinions.

 

Oh ok I didn't know patriot went under. My mechanic recomended those heads to me, and I was able to find some for sale on the interwebs lol. I thought about going for a max effort cam, but I think it would be a little to much for me. I'm really wanting the power under the curve to be good, got so much too end. The car will mainly be a toy/track car, but with a lot of street driving and playing another reason why I didn't really want to go max effort cam...as far as intake manifold set up goes, do you have any opinion on that? Thanks again for your input!

 

You might be able to get Patriot heads but if you have a problem with them you'll likely be on your own with no customer support. I can understand not wanting a max effort cam if it doesn't fit your vision for how you want your car to perform. That cam you have picked out isn't exactly small anyway. You may want to look at Tick Performance's cams also, almost all of them are designed for mid range and power under the curve but still carry it into the upper rpm range. The other good thing about them is they use more modern cam lobes that don't beat your valve train parts up as much as the old XER lobes but still make good power, sometimes more because of better valve control.

Single plains make more power with a 4bbl TB than with an elbow but either way they are hard to fit under the cowl. I'm not sure but I think you have to do some cutting and may lose your windshield wipers getting everything to fit. A FAST 102 cost more than a 92 and requires LS2/3 style fuel rails but makes more power. I'd wait to see if the new MSD Air Force 103 lives up to it's promises of being better than a ported FAST 102.

But like I said in my first post spend time researching everything before your buy anything and don't think twice about calling/ emailing several of the vendors on here to get there opinions also.

 

Sounds like you have the foundation for a quick car. I would suggest speaking with the different vendors and get a matching head and cam setup that will work with your future plans. Spend some time reading the dyno section and keep and eye open in the for sale section also. If you can afford it then spend the money on the heads, after all the work to install and tune you might as well spend the extra on what you really want or you will just end up changing out in another year or two.

 

I went ahead and ordered the VRX5 cam and the PRC 2.5 Ls6 64cc heads. Got a killer deal on a slightly used set locally. I also went ahead and ordered some green top FRPP 42# injectors, and fixing to order a ractronix fuel pump with hot wire kit, just to make sure I don't have any fueling issues. Now to just try and decide if I want a 92/92 set up or a 102/102 setup lol.

 

Congrats on the heads/cam combo! That combo should do well!

 

You might want to consider getting a Walbro Direct fit fuel pump and Caspers hot wire kit. http://www.ws6project.com/user_stor/...fit-fuel-pump/ http://www.summitracing.com/parts/cei-102150 https://ls1tech.com/forums/ls1tech-s...formation.html

 

Oh ok thanks, I'll check them out....why are the fast intakes so expensive?!?!?! Lol

 

Does anyone have any other input on the intake manifold? Ls6 be enough with my heads cam combo? 92/92 set be just fine, or the 102/102 set? Idk If the $1500 is worth it over the Ls6 Intake. Iv searched and see some people say stay with the Ls6 the others aren't worth the price, some say go 92 because the 102 is to much, and others that say 102 is where it's at.

 

Honestly if you look in the forsale section you should be able to find a used 92or 102 for a decent price. They are well worth the money in the long run.

 

So the added cost is worth it over the ls6 i already have in your opinion?

 

Me personally I wish I would have went with a FAST from the start. Leaves alot more room for power with future mods like H/C, I will be taking my LS6 off here soon enough and swapping it for a FAST92 with and EPS 222/226.

 

Ok thanks man!
