So what im curious is on stock cubes, how many HP do you think these heads could support?

Im running a Brett Bauer custom cam, similar to LE1

 

370-390 at the wheels with all the other bolt ons and a good tune.

Have you run this motor yet? How does it idle?

 

Idles great, you can tell its not exactly stock tho

Cruises well also, about 1800rpms at 70

 

Looking at the specs of the cam you would think it would have a nasty lope.

I will have a very similar setup as soon as i get the heads back from llyod. I was expectign them today, but they were a no show.

Whats your idle set at?

 

950 or so i believe, whatever PCM4less thought would be best from looking at the specs of the cam.
