Stepping up to a larger cam. My current set up is a set of Patriot stage 2 64cc heads with a Torquer 3 cam and a Un-ported FAST 90/90 set up. Looking into possible stepping up to either a T-Rex or an MS4. I know my heads more then likely wont have enough PTV. What set of heads would I benefit from the most? I know most of you will say ETP's (if you can find um) or a set of AFR's. Has anyone cleared with a less expensive set of heads. Just seeing what other folks are running before I pull the trigger on my new heads/cam combo. My Current combo makes 443 rwhp w/ 418 rwtq through a 4L60 and stock 10 bolt w/ 3.23s.

bro, those are really impressive numbers you are putting down. what size stall are you running? i think your better off investing in a 12 bolt or upgraded tranny. maybe swap to some 3.73 gears. you definitely would make power switching your heads out to a AFR, TFS, or even the new PRC 215 heads.

I'm currently running an SMi 4k stall, I want to dip into low-mid 10s and even with a built rear end and tranny I think it still won't be able to do it. I would love to runs 10s on motor then when it goes build my motor for spray. I mean with a built transmission and rear end I might pick up what 2-3 tenths?

you should be close to your goals. but if your rearend and tranny are stock, eventually its gonna give. so i would consider saving up and upgrading those and then maybe swap out the heads. but you are making great power especially with some patriot heads man.

Transmission is already taken care of. Rear not yet. Just trying to figure out a good setup with a larger cam. Car rarely see's the street. I don't know why people knock Patriot heads. They have always made great power for the money.

That is really good power! I made 443 rwhp with my M6, a 226/232 and a ported fast 92 with a stock 3.42 rear.

If it were me id go with an MS4, and keep the heads you have. Take that money and save for a built shortblock and buy the heads. Then mill them for more compression since you will have valve reliefs in the pistons and wont have to worry about PTV clearence.

I often wonder what my setup would make with some better heads, but it drives so nice I dont want to mess with it, just need to get around to installing my nitrous.

oh then definitely a 12 bolt with some 3.73 and maybe even 4.10 will help out alot. yeah, alot of people rag on patriots but lately ive been seeing patriots put down some good power. seen a guy with a trak cam ( almost like the torquer v3) and patriot heads making the same power as you.

Ive got the T-rex with patriot ls6's stage 3's and they work very well together. No issues

Your already making very stout power. Id say just do as Mrelectric03 said,
I wouldn't change your heads, find a cam that will go with the cam as it is.
Good luck!

If I were to swap in an MS4 I would have to fly cut. When the motor goes I already have plans to forged my bottom end and just build the motor for nitrous. I'm not going to go bigger cubes, for me im happy with stock C.I... Of course when the motor goes I will choose a set of AFR's or ETP's and run a larger cam with a 200-250 shot. I don't know if with my current set up if I could mill them from the 64cc there at now to 59cc but the bump in compression would be minimal power really. I mean I could port my FAST, mill the heads, throw on a better lid, and maybe 15 rwhp and the money spent wouldn't really justify the gain. Oh well guess I'll just have to wait.

i agree as well that those are really good numbers. i run the patriots with my t-rex and have never had a problem. but it was mentioned above that you might gain 2-3 tenths with a tranni and rear end. the question is what are your 60 foots. cause with a 9 inch/12 bolt and a good tranni can change et's tremedously. say you go 11.3 with a 1.7 60'. is you cut that 60' to a 1.5 then the car should run a 10.9.

My fastest time was an 11.45 with a 1.609 sixty @ 122mph. I need to get into the 1.4s to get tens. What is your setup with your t-rex?

my setup is a stock short block, t-rex, patriot stock valve 243 heads, lifters, pushrods, old flp headers with custom exhaust, victor jr, intake elbow, nw90, 150 shor from carb plate. was thru a t56 and 9" but am changing to th400 now

Don't swap camshafts. I think the Torquer 3 is a great camshaft for across the board power. The MS4 will pickup some peak power, but honestly it's not worth the swap at all. Those numbers are good! You could always get someone to port your fast intake & see where that gets you.

What if I mill my heads from 64cc to 59cc? If I was to do that and port the FAST maybe throw on my FT Lid I might be able to pick up some power. I need to get some gears in the car. Im pretty sure the 3.23s are doing the best they can.
