Here we are another winter and I have this intake in my hand with some real cool heads, one up for sure from last year.
Well the intake to head and larger carb to the intake aint cutting it either.
So, if dyno's are not showing any better flow numbers due to port matching....what is the problem.
What is it they yall do?
You can find allot of improvement simply by re-shaping the short
side turn and doing a really good valve job. Just these two things
will give you 20+% flow improvement.
Those shiney ports you see in that video? It's bullshit. one of my
friends from the old days called it "Fluff and buff". LOL It actually
hurts performance on the intake side. They do that crap to dazzle
and baffle john-q-public with BS. Jerry should know better.
But getting back to the origional question; Port matching does very
little, even on a set of good heads. Unless there's a huge mismatch
where the port is smaller than the intake flange, I wouldn't waste
my time. You can't measure any improvement on the F.B.
