Hey sup guys. I am building a non turbo 13b. I have ported gsl-se housings that are ported and notched for bridgeporting. The motor had 6 port streetport irons on it before I blew it. I was wondering if 4 port or 6 port could generate more power? Can put a big bridgeport on a 6 port? Basically give me the run down on power potential between 4 and 6 port. If I switch to 4 port do I need to change eccentric shaft and all other parts from a 4 port?

i looking to be getting 300 hp out of my 6 port. with the right porting and tuning that is very possible. 4 ports might be able to make more power not too sure though. hopefully a 4 port guy will hop in here to give you those answers.

The internals are basically the same, the plates are also basically the same minus the way they are ported. Its like saying if I take a 13 streetported, would I need to change to the internals of that engine or could I use stock port internals.
