Brand New CNC Inc heads and used Comp Cam!

**onelife** · 11-03-2005, 09:02 AM

I have a set of Brand New 5.3L Heads that CNC Inc ported with their 5-axis program and if anybody knows their work, they look like jewels.

They started on a brand new 5.3 casting and the heads themselves have never been used.

The Comp Cam has a 100 miles on it, .535" of lift intake and exhaust with a 224/228 duration.

This cam has the duration CNC Inc calls for the head but CNC Inc also calls for at least a .570" range with that duration. Well this cam has less at .535" with a 1.7 rocker ratio, with a 1.8 I imagine you can hit around .550" coming closer to what everybody likes.

Make me an offer for either both or seperate. Thanks.

Just curious, how much did CNC charge to do the porting?

I believe it was $2200 back in 2002 when the heads were done, I imagine they have gone down since then.

No, I did not know these rules. First $1000 OBO takes the heads. First $150 OBO takes the cam.

What time of HP # can be expected?

Will the Heads and Cam work on a '98 Ls1 TA?

Thanks

Pics can be viewed on Ebay,

the heads and cam will work on a '98 LS1 TA but horsepower may vary on certain vehicles.
Providing on an F-Body, you have long tubes, free flowing exhaust and induction, PCM tuning, and depending of condition of vehicle with an experiance mechanic installing them

400RWHP to 425RWHP will be expected, more power will come from a higher lift ratio and/or on a Y-body ( because of the true dual exhaust ).
