Hi there, I'm new to the site and have been led here chasing any info I can on anyone that is, or has, built Performance Alloytechs for Racing. The only info I have been able to find on the net so far is the Formula 4000 category. And I haven't been able to find their rules and regs yet. We are screwing one together for use in a speedway car (VZ). Our rules are basically unlimited except for no stroking and must use original heads and block and inlet manifold.( this is a basic run down, there is a lot of other rules.) After market computer etc will be used. Can any one steer me to where I might find some info? Thanks
