+1 420-440 is a respectable gain to the wheels

Mike@TEA

The power numbers they use to advertise their kits are actual flywheel horsepower and torque figures from a superflow 901. What they do not advertise is what other components are used to get those numbers. Those were made on a stock shortblock using their kit with an LS-6 intake. The same kit with a fast 90 will also produce 540 flywheel HP. I am posting 2 dyno graphs of all 3 of their kits one is with the LS-6 intake and one is with the fast 90/90. This is very good/accurate information that shows what power levels do with regards to camshaft changes and intake manifold changes. The heads on this motor were also unmilled and left at 64cc and stock Gm head gaskets were used. Enjoy.

Fast 90 Intake

How much does 540 FWHP translate to at the tires ? 460-470 with a 228 cam! Imagine what would happen if the heads were milled to 58-59cc and and 240 camshaft is installed. You would probably make 570-580 fwhp which is exactly what all the 490-500 rwhp guys are doing with these heads. Those packages are very well thought out and proven but may be a little on the conservative side for most people on this site. It is my understanding they were designed to deliver good power with good driveability and still be easy to tune. The TFS 215 is about as good a head as can be bought for the 3.900 bore engines 5.7 engines regardless of what this flowbench or that flowbench says.

Jeremy Formato From Tampa Bay has tuned many cars with these heads. I've seen the dyno sheets. T/F heads work very well on a dyno and on the track where it really matters. Contact Formato Fastproms. He is a sponsor on this site.

Does anyone here run stock heads with port and valve work done? i want to keep as much stock appearance as possible for the mustangs and ricers on the street. Who would yall suggest to have stock heads built, and will it be enough for my x3 cam to breathe through??

The ricer guys wouldn't know a set of trickflows or afrs if they hit em upside the head. Most those people don't know what an LS1 looks like. Besides the heads are hidden pretty well. They'll know the fast intake manifold and the sound of a healthy cam. But I know some people who make a good amount of power through stock castings.

I hear ya, but i would love nothing more than to hit some et. in the tens and be able to bragg about a complete stock block and head setup. I'm only setting aside 1,500 for heads, and i want to see how far OE will go.

In the Summit advertisement they say this kit will make 515 hp. with 10.5 compression. My question a stock LS1 is not 10.5 compression is it??

Last C5

No, but it will be if the heads they provide are milled correctly. My track partner just installed a 228/230 cam and ported LS6 heads on his 02 Z06 and it dynoed 421 RWHP on a Mustang Dyno. That car also has Dynatech long tubes.

Im using patriot stg 2 heads and the trick flow stage 3 cam, I put down some good numbers to the wheels. The trickflow stg 3 cam is small compared to whats out there but, looking at some peoples sigs with bigger cams the horsepower numbers are close to the same but, Im usually putting down more torque. I think trick flow did well with there setup. This package they offer is more on the lines of something thats convient for the consumer looking for h/c and everything else hes going to need for the install and wants to make good power.

LT1-DAN

Do you know if there are any driveability issues when using a large cam? I am looking to make my car a fast street car with maybe 1-2 track days a month. I do not want to sacrifice the good street manners of the car.

Thanks man. That's exactly what I ment.

Mike@TEA

I actually calculate stock compression around 10.25-1 with stock 67cc heads. With the 64cc heads I calculate around 10.55-1. Most all of our customers have us mill the heads down to 61cc to get close to 11.0-1.

515hp at the crank is very reasonable.

I have been doing alot of research on H/C packages, etc. Alot of different stuff out there.

I'll post my numbers in a few weeks and bet they will be around 500rwhp in a 346 vette thru 4.10 gears with these head/ and a stout cam.
Mike and Brian are awesome to deal with as well. Very professional and informative.

I run a stock 241 head milled down .015 and stock gaskets and figure mine in at 10.5 to 1. mine are mildly ported and only flow 256@.500 and 257@.600. mine makes 441/410 all that with a 230/232 cam.


I do have the fast 90 though.

This is a combination that I have seen a TON through the years around here....makes for a VERY serious street car IMHO...especially if you bottle feed it

I have those heads milled to 62cc with a custom cut Allen Futral cam. Check out the video in my sig.. This is a Stock bottom end motor, full weight 3600lb car with me in it, PTC 4400 stall converter, strange 12bolt rear end with a 4.11 rear gear and 28" tall tires in the rear..

no, thats terrible for a set of heads that are capable of MUCH MUCH more. seeing as there are plenty of guys CAM ONLY making 515 at the flywheel (420-440whp), why use a package that performs way off par?

you shouldn't have a problem making 460 - 480rwhp with the proper heads, cam and INTAKE, with very street-able cams. if you want to go more wild, do it. you can get 500whp. you're gonna be spending A lot of money, make it worth your dollar. 490 - 500whp is attainable with a well thought out combo. its all about the parts you use, and the tune.

as for the streetability of the car, obviously cam selection plays the biggest role.

can you give us some info about the car? auto? stick? gearing? weight? how hard do you want to rev it? is it carb'd or FI?

that way we can help you select a cam for this setup that'll get you gobs of power and still remain very streetable.


EX: i just installed an ms3 in my buddies camaro, and honestly, besides a bit of bucking at really low rpm's (sub 1400), and the choppy idle, the car drives very well. this is a pretty damn big cam for a little 346, and even with the stock tune the thing drove great! with the stock 3.42 gears you did notice the bucking just a little, but the car's a 6 speed so he just slipped the clutch a little off the light and it was fine. now, the power comes on a little later in the rpm's, around 4 grand, but when it does its nice! with an auto, the bucking would be more noticable.

the specs on that cam are 237/242 .603"/.609" on a 112 lsa. a cam with pretty simmilar specs would be capable of 500whp h/c/i, with the right combo. compression is also going to play a big role in making a number like that.

TFS heads alone can make a huge difference! I gained 60 rwhp just from TFS 215 heads on a Procharged stock LS1 and stock cam.
