Jeeeeze, is that cold or what? To apply Dahlgren's law to C/GT; If it was
easy, anybody would do it. Don't see anybody's name anywhere in the record book
:-)
BTW, if you dump a 300 HP NOS hit onto a stock Vette crank, it will take us an
hour out on the salt to pick up the pieces..............................
