Default Re: Curious about the engine, :question:

the super rat? i would wait b4 jumping on that price range.

there are no 40mm stroke pk80's left then the gt5 setup should be the best stock but my gt5a will be timed higher. once the squish is fixed i see i have no competition.
only question is do i use the gt5 or gt5a cylinder

in theory anyway. this must be what fred is talking about? or did i get it wrong somewhere? am i jumping the gun on this?
