guys
thanks to all that have given support, now i'm confused a bit, not unusual for a Canadian.
i like the idea of using smaller cc heads, say 100 cc, i believe that would be a managable cr

i raced this in the 80's, with good results, in street trim, i'm looking for that power out of the hole and if i can achieve will be quite happy.

thanks again to all
