Texas Speed LS3 Engine Dyno Testing New products!! - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Guys I'm proud to say I finally have the final version of the all new PRC 255 & 260cc cylinder heads finished & ready for dyno testing! We are also testing a few new camshafts that will offer some nice dyno numbers along with making sure to keep proper p/v clearance!

The PRC 255cc cylinder head will still feature a 2.170" intake valve & have much better pv clearance for extra milling & therefore more compression! I'll get you guys some dyno videos & pics up in the morning along with data from what we find. I think you guys will be very happy with the results! a 370cfm cylinder head & a new camshaft profile that's different than anything anyone else is running currently.

Keep us updated for sure.

If you need someone to test let me know Jason. I have your 250cc heads and 229/236 cam. I spoke with John about the numbers also.

I'm watching this closely too as this is one of the mods that I will be doing this winter. A question I have Jason is, will these new parts be a part of the PRC heads/TSP cam package that you offer now?

CGT · 10-05-2012, 10:12 AM

Where are the results?

dekan513 · 10-05-2012, 10:36 AM

thanks guys for checking in on me! I have another custom intake lobe on the cnc today that we will test hopefully by friday. So far im up about 20hp over our 231/236 combo & cnc ported ls3 heads. Basically we're talking 600hp on the engine dyno with stock short-block & stock ls3 intake manifold.

Dekan,

yes we can mill to 65cc and keep better than stock pv!
