JASPER Transmisions ??
I got one of there 360 v8s a few yeas back. Got around 100k on it the miles on it have been less than gentle. It's held up good. Don't know about there diesels though.
I put one in my old half ton gasser. It was okay at best. I wouldnt advise putting one behind a diesel. I gave about 2400.00 bucks for it too. Not cheap. That was about 7 years ago. Just my opinion.
Jasper does a good job on eng trans. I have not hard of them bilding one for high HP. Jest give them a call and they can tell you. JASPER Engines & Transmissions: Remanufactured engine: diesel, marine, import
