Your engine builder is WRONG and the geometry isn't correct. Is it good enough? Maybe. Is it correct? Nope.


Why push it? You've spent all the time and money. Fix the geometry. If the engine builder thinks half assed geometry is good enough, I'd be finding a new engine builder.


Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston
