NAH2B This question is for u

So how far are u on finishing the new header and testing the new bigger tube primary. And also since u have skunk2 as a sponsor have u ever tested the pro2's in ur setup just to make a comparison and track test and dyno it to see the gains u may be able to make more cam gear adjustments with a camshaft with lower lift.

I see there is a big difference between the pro2's and pro3's as far as the opening peak and closing event's by 4-6 degrees maybe u can shift ur power band using the lower lift cams by using that advantage. Also seeing if u have already done this also.

I know it's kinda getting off the subject but love trying to give my .02 cents to help someone into better et's more mph.

nope didnt test the pro 2s, gonna stick w/ the 3s.

im still trying to decide if im gonna do a side exit or another under the pan header, so i havent started on it yet other than opening up the flange for 1 7/8" tube.

im planning on getting it done sometime this month so i can hit the dyno and test a few headers before the IFO race on June 11th. theres just not enough time to do it before the june 13th race next weekend.

when i get close i will let everyone know and they can send me some headers to test. if you guys are gonna send me anything w/ 1 3/4" coming out of the head make sure to grind it open as much as you can...

So y not test the pro 2's just like u would test a smaller header like the kidd racing header that's not built for the engine. I mean i would dyno and track test just to say that u can rule out that the pro 3's are the perfect match for ur setup u might be surprised.

Like with my custom ported intake manifold that i have i'd love to test it against a skunk2 or euro intake manifold to see if i made a good design or if it works for my setup which i'll be doing soon a buddy of mine has one.

the pro 2s dont fit my build, they are to small and will make less power so i have no interest in testing them...
