<x-charset iso-8859-1>That was my problem when I built my motor... reccomendations from exactly
opposite sides of the CR issue. I couldnt find any examples of high CR
engines with high mileage, but Berg could prove his reccomendations on his
motors so I went with him.
I can say that the semi hemi and low CR on my Notch runs very cool, gets
better gas mileage than my Stock Square, and went like a raped ape up the
mountain last weekend when I hillclimbed it... almost 2 minutes faster than
the square and I wansnt all out... and I still have those lousy little foam
air cleaners on it.
... just my experiences
