415HP from 318ci IS POSSABLE!!

I beg the differ, i rekon it could be driven on the street no sweat
at all an on pump fuel.

Pump fuel? Sure. But that's not where the problem lies.

Like weve said before,what 1 person finds streetable
another might not.

Absolutely, everyone has there idea of streetable. I said it wouldn't live on the street. They had a hell of a time getting those rings to seal on the dyno, not good. He also shrouded the cam tunnel, good for the strip, bad for street longevity with no oil splash on the mechanical roller lifters. The valve margins would also have to be in the neighborhood of 1/32 to get those heads to flow they way are. That engine would not live long on the street. Add in a yearly break down to check the mechanical rollers and spring pressures and it's not what I would reccomend to the original poster as a daily driver.

If you consider a 5000 rpm torque convertor, 950 HolleyHP and 4.88 gear ratio streetable, more power to ya. :-D


15 grand? Dunno bout that, but yeh engine coatings an some
of the other stuff mentioned isnt cheap..
If it DID cost 15 grand,id go 426 hemi every time...
Never see them here in aus..

The machinist took 5 pounds off a 340 crank and got it balance. The mallory metal alone would cost 500 bucks. I'd say there was 4K+ into just the crank including turning down the rod journals, profiling and re-hardening. That Holley 950HP runs about $800 before any of the custom work was done. Custom Diamond pistons are over a grand, not including the machinists time to measure everything up. I see this build topping 5 digits easy.

Now here's a build that 470 HP at the crank by BJR Racing: http://www.forabodiesonly.com/mopar/showthread.php?t=28974

It could be done at less expense than the aforementioned build but if you PM'd BJR, I imagine that he wouldn't call this a daily street driver. :)
