i have to intakes that im looking into putting on my new motor build.
its going to be a 355, flat top pistons, 210cc heads, 268xe comp cam. im not sure compression yet ill kno more when i take it to the shop. i dont want max spin to go over 6500. i have the summit racing air gap intake, and the weiand 1546 intake. which one would be better for the street and possibly a trip or two to the track?

 

Why such big port heads then?
Guys run 195's on street 383's

nobody has a comparison with the INTAKES?

 

I think you wrote the wrong number. I can't find any weiand 1576 intake.
I would go with the summit one anyway. It's just a copy of an edelbrock air gap.

btw as vetteoz was eluding to, you heads and cam are mismatched. Unless they are procomp heads. Then they are just mismatched to basically anything.

 

For those heads you would want a single plane high rise and you need a different cam... It would be pointless to only use those heads for only up to 6500. That size runner likes much higher RPM's.

 

which cam would be more "suitable?" I have a thread going under
'help me pick a cam" abd everyone says the 268xe was the cam to use. also whats a good high rise intake to use? I apologize its 1546 weiand intake

 

Ah they are procomp heads. You would have been better off with a set of vortec heads! I am surprised your engine builder hasn't said anything to you about the heads. There is no good cam choice because they flow like a head with smaller ports but have the low end velocity of heads with bigger ports.
And don't use a single plane high rise intake with those heads and cam it will be even worse than what you have now.

 

so your saying I cant "match" the heads with anything out there?

 

no, but it will never be what it should. Might as well just use the cam you have.

 

Please disregard my previous post, I missed where the heads where mentioned. I was thinking Profiler, I should have known better. Like what was previously mentioned, you have some mismatched stuff. I would run the Air Gap and port match and keep the cam you have.
