Allison MT654 beef-up?

Does anyone know of a shop that builds medium duty Allisons?

I just picked up a p-pumped IH 4800 4x4 to replace my F-450 for gooseneck duty. I'd like to juice it up around 5-600hp but I know the Allison is the weak link. Obviously a stick would be the easy way out, but I like the auto's for pushing snow and I know there's no way I could row a 9 speed or an 8LL fast enough to take full advantage of the power.

I know Kyle Dunkle was putting 1200hp or so through a 545 Allison in his drag truck but I havent seen him around the truck shows in the last 2 years or so.

A little off topic, but is the motor a dt360 or a dt466?

It's an NGD DT466. The truck is a '95. It's one of the last mechanical DT's so its got the roller cam, better flowing head, ect.

Plan is fire rings, valve springs, slap a 12mm Cummins P-pump on it an S480.

What the hell is ngd? And is the 12mm a stock pump or an upgraded one?

New Generation Diesel. Most call it the DT466C but the real name is NGD

Stock DT pump is 10mm. Cummins pump is 12mm. Swap the cams in the pumps and its a nice little upgrade.

Groovy

Got any pics of this truck?

This is all I have on my phone. I'll get more

Oops try this one. Anyone want a boom lift body?

cant answer your question but this is a pretty sick build. you should start a thread for it

It's gonna be a slow build. We are slammed with work right now but I wanted to get the truck purchased before the end of the year for tax reasons. It will probably be next spring before I can work on it. Got my hands on some 16.00r20s from my natty guard unit so I might try and get those on there soon though
