I'm very pleased with my 440Source kit. On the other hand, a guy I know ordered the Muscle Motors smallblock kit and the crank journals are square. Two years later and they've still failed to provide ANY sort of solution. All he was asking for was a set of o/s bearings so the machine shop could correct the problem.

I've no doubt that for every bad situation there are 20 good ones but failure to resolve a simple issue with an inexpensive solution is enough to make me avoid them.
