Lay I wish I had something to tell you. But here are a few of my observations. I run them in a Micro-burst Mono. Spokane is at 2,000 ft. The first motor which I have worn out was supposed to have been done by Andy Brown. Ran it with a K&B red carb, OPS pipe. It indeed has some of the most interesting port work I have yet to see and everything inside has been touched. I would call it maxed out. Tried this motor with several different carb and pipe combo`s but could never get it to really scream. It would pull some rather large props although it became very pipey. Maybe should have tried this motor in a hydro- less drag. The pro I ran last year came from a very OPS knowledable boater who has since passed on, Mike Shane. With this motor a K&B black carb believe it or not and the same old ops pipe, the pipe looks like I got it out of the garbage can, the thing runs much better. The only thing apparent inside this motor is the crank has been turboed and the piston is skirted. And of couse I am sure both motors were blueprinted. I am quite happy with this motor, although it will not run with the Macs it runs right next to the greenhead in our club and easily outperforms the K&B`s. So I quess I would say just a little help inthe breathing department and the attention to detail when putting it together and a little experimenting and these cheap motors will run right in there.
