If you're gonna gear it like you'll always be racing for money, the ZF will
likely hold together but production engines will get used up pretty fast.
My suggestion- phone or fax Lloyd Butfoy and ask the expert's opinion. He has
many possible ZF combinations- including a 6-speed- but you need to discuss
them- and their costs. My 2¢- J DeRyke
