Well since I am getting a new Crank anyway... I might as well get a longer
stroke and Make this thing a C Motor ... Brad's got an extra Vette or 4
hanging out around his Place.... Hmmm C/GT ain't that a SOFT record....
Keith ( yeah you can Pick on Me... but remember I pick Back......shoot... I
might even get LUCKY...)( hmmm gotta go faster then this Brick...and NO ED
I am NOT SERIOUS.... )
