The 315 stuff is good....real good!

Damn!!! Nice numbers Lem and Phillip.

Nice build Lem, can you give any details? Are the heads out of the box cnc ported, or did you rub on them?

What cam and compression? Fuel?

It's Phillip's compression ratio and fuel so, you'd have to ask him.

It's my cam.

Very nice build gentlemen !!!

Guess that answers the "Will they support 1000 hp out of the box question" ...

...and at 6,500 rpm no less.      

There is most certainly some more there by working the as delivered AFR intake.

Again nice build !!!

The cam is a bit different than usual.

Once again, a display of what is possible when the right combination of knowledge and ability is applied to ones craft.

How was the torque Lem?

How did that compare to the 588" p-51 build you and Phillip did?

Nice work guys. Were the heads and intake bolted on as is or did you do some port work on them?

Thanks,
Butch

Got pleanty of good heads available, now we just need some better intakes to get some RPM to make more power.

The head and manifold castings were not modified.

Nice job Lem and Phillip!!! Nice numbers!!

Clearly a bogus marketing ploy.

(joking)

Impressive work. Congratulations!

Sounds like a great option for a really good bracket engine that does not have to turn high rpm.

Considering the oil pressure....who can correctly guess the inches of Hg the vacuum pump was producing?

I just re-read through this build and maybe I missed it, but what is the bore & stroke?

Thanks, Sheldon

Nice flat torque curve Lem. Any details of the combo ? I know it has the new AFR heads on it.
