What's a good start to compeat agains't them Hot Farmall M's there are a bunch around hear with
421 cube's making I dont know how much on the dyno, make's me sick. Maybe a MM-U ? I'm a machinist and got a good work shop boring bar, mill, lathe, welder's. what do I need to start looking for?

I have a complete 403 that could be bolted in your U. It would make 85-95 hp properly tuned. 319 404 5146

What else would it fit....a 670 Super maybe? How much do you need for it?

FInd a set of the rules can be lots done you could lighten a GB and pull in the same class as those M's and be competitive or build a U take we got a couple running around here with built 336 CI milled heads ported bored custom manifolds and cam work they win pretty regularly or could go the 403 route in the U then work the engine over. Money is the only obstacle but you took care of a lot of that if you are a machinist
