Thanks
I have a freshlly rebuilt mach that I've been thinking about tring my hand at porting on.
Have you seen Jefex's porting thread ? That would be my guide.
My Cen Genisis will never be a racer and I can't get replacement parts locally, so I don't drive it much, it's a big heavy truck. Do you think it could be a good puller?
Thanks again for the info.
Ben
