Im on TSP's website now, do ytou guys think the PRC260's are better for a daily driven street car or would the PRC255's be better suited?

Will the PRC260's gain higher RPM peak HP at the expense of low/mid range torque?

frankwjr · 02-12-2018, 04:24 PM

just wondering what kind of input Cunnigham had on this...since they are doing the cam and tune...head selection has a huge impact on the cam grind. obviously getting this part right makes tuning easier and gives the best power output. good luck OP! peace out...

5 cc's wont make any difference! Your cam is going to determine the rpm range of your engine and where it makes torque best. Its all compromise! The only way you will truly see the benefits of the heads is with a big cam and twist that motor till 7000 rpm. Now what your left with is up to you when it comes to determining if that is what you want for a "daily driver". Dont spend 2600-3000 on heads unless you want to max that bitch out.

Bo, did you have to mill or do anything to the stock LS3 intake manifold to fit it to the milled 65cc castings or did it bolt right up without issues?

I personally run the PRC’s. The combination and use would dictate what heads to run. Mast black label with adapter plates can work too but looks like overkill in such a combination. Good luck in your search.

I didnt touch a thing. Everything came out of the box and assembled.

Take a look at our GPI max package, thru the end of the month we are also offering trade in value for you LS3 components no longer needed. PM me if you would like details

I'd go with a Trick Flow Top End kit for your Engine. Trick Flow takes the time to design their products to make the most power. It's well worth the money.

Bo White · 02-13-2018, 04:01 PM

I would think every aftermarket cylinder head manufacturer tries to do that.

We have engine dyno data on LS3s with our cam/ls3 head package. With and without rod mod intake and ported rod mod intake.

We just finished up the testing on the LS7 Max top end for the LS3 platform.

Results will be posted by the end of week hopefully.

Bottom line is it is the most powerful top end combo currently out there for LS3s, while still utilizing hydraulic roller cam and factory style manifolds.

High ram or carb style intake with a low lash would be absolutely ruthless, but that would be more suited for the extreme guys, and or guys with more cubes.

Lets see what she does with a nice cam and these heads
