415HP from 318ci IS POSSABLE!!

Mal,
The 501 HP is without the air correction factors, the 470 is with the air correction factors. Flywheel to flywheel. I changed the intake and the carb and hedder size, this is where it picked up the TQ and changed the HP some in the lower RPM ranges. Doing this made it much more streetable. The engine that I used is the 322 and in race trim it made 535 HP and just over 500 ft lbs of TQ.

As for tires and gear I would use a 3.55 or 3.73 and a 3500 stall and a 28" tire. The actual stall will be much lower I would guess somewhere around 2800.

Smooth,
I've made trips to TX. before and I could do it again, it cost me about $400.00 rd trip. But your a bit further so maybe a couple of hundred more. I went to Warren,TX. last year to deliver a 360 street engine to a repeat customer. How much farther would you think EL Paso is from Houston? I'm just using this as a reference point, I haven't looked.

The carb would be a 750 cfm. And yes dynoing would be more, but have access to them. I priced this using your cores. If your in a hurry you could hear the 322 engine run and take it with you 1 hr. later. I'm not that fond of any engine that I build. I've had many customers say that they want the heads that I run because they think that there's something trick in them, most of the time I use my engine to figure out what works and what doesn't, kind of a test mule. I think that 7.40 @ 96 mph 1/8 is a good test for 87 octane fuel, as this is what it ran just 2 monts ago.
