ok i just got my AFR 210 eliminator heads, new cam, and a total refresh done. and my old intake (Victor JR) is WAY too small for the intake runners on the heads. so i was considering the new AFR composite intake, however i plan on spraying a 150 shot and im not sure that the plastic intake would handle a backfire. so what are your thoughts?

Why not port match the 1206 gasket alignment of the head to the intake?
Well I'd like to have a higher intake than the victor jr! I also just want a new one, cause everything else on the motor is new!

Super Vic.
But port it as a super vic will flow about 295CFM out of its best runner and the 210 eliminators will if you are .650 lift flow about 310CFM.
Most guys don't bother to port the inside of an intake, but if your heads flow more than the intake, why restrict those good heads. Port match to a 1206, yes, but follow that up by porting the ENTIRE runner.

This was my point with porting the intake to match the heads. Here are pictures of my big block Super Victor on my 540.

Well, my cam is has 630/630 lift with 262/274 actual duration. Now that being said, do u think with that cam it would be worth the time to port it?

You are looking at about $600 to port an intake like that. And it may only get you 10-25 hp. You need to ask yourself, how much power are you trying to make? And then decide if it is worth it.
Are you referring to the super victor? Cause I can port that myself.

The concensus on Vic jr vs the SV is the Jr will make more bottom end and will give up a few ponies on the top end to the SV. My motor is similar to yours head and cam wise and thats exactly what I saw. I lost .1 seconds in the 60' but gained about 1 mph in the 1/4 mile. Over all the car lost ET so the Vic jr went back on.

I could have had my converter loosened up a bit to take advantage on the new power band but it did not seem worth it to me on a street car. My converter already flashes to about 4800. My car runs mid 10's with a pump gas 406 on the motor.
