Barrel rolls are easier to do with 'b' pipe LIMITED chamber motors...:Banane01: THAT WOULD MY CHOICE IF I WERE YOU...(you gave up low hit with those porting spec's :rolleyes: )

I have the sport port (well exhaust side only, had other help with the intake) with a limited and it makes nice smooth power. I'm a wuss, but Marsh was pulling no-handed rolls with mine and attempting double troubles. (1 1/2)

How does the sport port template give up the low end hit?

I forgot!
and what about the new freestyle sport port, it didn't raise my exhaust port just widened it, come on fill us in, i am also running the limited chamber. and by giving it up does that mean it can't be undone even with a new bigbore sleeves?

my understanding is that cutting the intake sleeve the length of your "boost" port which lets you build rpm faster but you loose down low hit.

original sportport has you shorten the intake and also notch it.
freestyle sportport has you shorten but no notch.
(just comparing intake, exhaust is different too)

i believe geek compared his and smittys engines that had sportporting where geek did the intake and smitty didnt. smitty had better low end but geek was stronger on the mid and top. dont quote me on that story but i usually have a good memory.

I just did my second cylinder - granted, I didn't use the sport port at all this time.
However, my previous cylinder was very much the same, except for the intake sides of the sleeves.
New cylinder doesn't have them cut at all - better power I think.

Matt,
So you just ported exhaust on the new cylidner, and then matched/blended the transfer ports to the sleeve? No work to intake/boost port part of the sleeve?

Well....I did work on the bottom portion, but not to that area that the sport port wants you to cut into.
