I'm also very happy with the stuff ive got from Dax but I do wish he would get some more bottom ends again soon... I got a good collection of cylinders, pistons, and heads waiting for bottom ends and I really don't want to risk getting another badly unbalanced vibrating piece of junk from another source... this guy's engines and bottom ends are very well known for their smoothness so when he does get bottom ends he sells out fast. I would buy whole engines from him but half the fun is building up the engine and I like to do my own thing with the top ends. I may have to resort to buying cranks from him and building up my own bottom ends if he don't get anymore soon...
Ive tried getting engines and bottom ends from other sources but they all shook badly and none of them turned out nearly as smooth as the Dax based engines I've built.
