Hey guys. Looking to upgrade my cam only LS1. Currently I have a 224/224 cam only 01 a4 ta. It has a 4k stall and stock 10 bolt with 3.23 gears, stock unported 241 heads, ls6 unported intake. The car currently is putting down 403whp 376tq. I have taken it to the track several times and runs a consistant 11.9x at 112mph.

I am looking at doing a head/cam combo from Texas Speed. The combo I am looking into doing is the 227cc PRC heads and either a MS3 or MS4 cam.

Have any of you done this combo? If you have, what kind of power are you putting to the tires and what e.t. and mph are you running at the track? I am trying to decide if this is a good combo or if there is anything else you guys may recomend that may be a better combo.

My goal is to get my car to run mid to low 11's while still being able to drive the car on the weekends.

Thanks.

Who tuned your car and what converter is it? It should be trapping around a little higher now in the 115+ range. If you are sticking with the 3.23 I would get something smaller than those 2. TSP torquer is a better cam for your combo. I would be willing to bet you could just do heads with what you got and get 11.50 if everything is set up and tuned correctly.

@ Killer5.3.

Converter is a Yank SS4000. I have a set of 3.73 gears waiting to go in the car, I didn't put them in because I wanted to see what the difference/gain was going from a 3200 stall to the 4000 was, without my e.t. being influenced by a gear change. With that gear change, would those 2 cams work correctly? Thanks for your help.

I would keep your Cam and do a Head and Fast intake swap. That should get you into the low-mid 11's and keep it a great driver.

I think this would be best option.

If I keep my cam I would be sacrificing the extra power by upgrading it to something more aggressive. When I do the head install I will be pulling the motor so it makes sense to upgrade the cam at the same time, while the motor is out. No sense in doing it twice. I am aware that I am sacrificing some drivability, but I am thinking that a bigger cam as well as the heads will give me the result I am looking for, instead of just doing heads and keeping my cam. Thanks for the input guys. Is there anyone out there that has done this combo? Or something similar?

Has nobody out there done this combo or one similar???????????????

The SS400o is a very good converter , but, if you are dead set on a bigger cam than you have, I would get a good cnc ported ls6 head and get with Patrick G on here to spec you a custom grind to work with your combo. If you did that and the Fast Intake as was suggested you would have a very low 11 sec car on your hands. You will need an injector upgrade though.

what you have speced out is a great combo of cam and heads...

I have basically a ms4 but with LSL lobes on 111...The setup makes huge power...

Also note I have TFS 215 heads...

Thanks for the reply! How is the drivability of your car with the big cam? With the TFS 215 Heads you dont have any PTV clearence issues?

ms4/head combo has fine drivability if you install the 3:73's and good tune

Thinking about this combo (MS3 or 4 and PRC227) for my 6.0L Lq9!

Just call Texas Speed and go over your setup with them and they will set you up right!

Read my Sig. Went an 11.302 @ 119.6 with very lil weight reduction , not the best heads and a lil bit different cam than what you already have and I get 23 mpg on the freeway. Just my .02 cents

If i went TSP i would go with the PRC 227/MS3 combo or Tsunami.

Hadn't been run at the track yet, but, guy bought my 02 Hardtop SS and did TSP stage 2.5 LS6 heads, Tsunami cam, LS6 intake, kooks headers, etc. Just freshened up the bottom end w/ forged pistons, stock crank , and rods. It put down 440 thru 12 bolt and will pull new Z06 from a roll. It sounds badass thru borla exhaust with the baffles out. Only weight reduction is spare, jack, and greg weld wheels.
