I wouldn't put that much power in a T4, they can be kinda fragile everywhere but the tranny. T2's can go for as little as $60 on ebay, and are built like tanks. I got mine for $30 as a roller missing some screws and the steering bellcrank setup, but it had Lunsford turnbuckles all around at least. I put a few bucks into it, and ran it with a Lehner 5300 for quite a while and had a bunch of fun, still haven't broken anything either......and I don't exactly go easy on it.
