cool, thanks guys. i was counting that with my choked up cast iron heads i'd make somewhere between 450-500 hp. This has been a ride. For $2500 I've managed to put together a complete engine and valve train minus the head castings to put the valve train into that is capable of 500+ HP and a healthy shot of nitrous. Not bad in my book. Granted, to make this puppy into a fire breather monster, you'd need to put some money into a good pair of cylinder head castings. However, I have everything needed to assemble the cylinder heads/valvetrain. Not bad. Just wish i was still into the racing scene and still needed this motor

I gave the specs to those particular cylinder heads because they are the only pair that I have. The thought crossed my mind to use them, but i knew that they wouldn't breathe well enough for that cam and the chambers would be too big to really let that cam rip. I just thought that if the motor made decent numbers with those old heads, it would make great numbers with a good pair of heads.

Also thinking of selling this motor to pay for my books and tuition for my college classes. What would be a fair price for this motor? (I have everything except carburetor, distributor, and cylinder heads. The valve train and shortblock are complete)
