Paul,

Thanks for your explanation between side and peripheral porting, which changes
the size, location, and overlap of the intake and exhaust ports. How about
explaining "bridgeporting," another term I occasionally hear about modified
engines?

Thanks.

Barry

O boy! I think I'll beg off on that. Maybe Paul Yaw would like to take
a crack at explaining bridge porting. That is radical surgery as far
as I am concerned. It was invented to circumvent silly auto racing
rules.
They could not beat the rotary so they tried to outlaw peripheral ports.
