Hello, ive been reading your posts about the engine. I feel that your quest for the most power out of that engine is well, a waste of time. A low line nova rossi like the ison line($150-200) with all the work you have put in would show much more fruit in terms of speed. You are going two different directions at the same time. All the pull start parts off the end of the crank are heavy and alot of drag, even if you put bearings in place of bushing. If you were to mod more of a race engine that has proper piston sleeve fit amd the right touches, your car would be much faster for sure.
