Default Realistic numbers with these mods...

Hello. OK, I'm a newbie to the forum and I was just hoping for some insight here. I have a '99 FRC that I want to install the following parts on and was wondering what kind of numbers I can anticipate seeing. Hope you all don't mind helping a "newb" out.

'99 FRC with SLP loudmouth axle backs
parts I have:
Ported 853 heads also milled .030 in to "bump" the compression a tad
Thunder Racing TR224 112lsa cam .565/.565
Breathless LT headers
Will be dyno tuned.

CONSIDERING an LS6 intake manifold.

Any insight would be GREATLY appreciated.

Thanks in advance.

Figuring that stock it's probablly in the 320 range that's a pretty nice increase and some nice numbers. It should also still be very streetable while being even more fun than she already is...sounds promising.

I'd guess around 375. Depends on the porting job on those heads. Intake would help and you might as well get it on before the tune

would definitely recommend an LS6 intake. It's much better than the 97 to 2000 You can pick them up on E-Bay pretty cheap. Just make sure the part number is for an LS6 PN12573572. Also a good C.A.I to help it breathe a little better. I like the Vararam

You can get a ported LS6 intake from bare essential racing for about the same price as a normal LS6 new.
