Re: Ported Intake for Sale
 

Bob what level of port is this ?

Re: Ported Intake for Sale
 

This is designed to go on a stock or mildly modded 350 cid. Pretty much anything else is going to have ported heads and you'd want to match the intake to the head porting. It's 36+mm throughout except for the primary runners which funnel down from 36mm about half way down the injector housings to 34mm where it meets the head - stock primary head ports are 32mm at the gasket surface.

Robert,
Excellent work!
Tell us how you managed to finish the runners inside the plenum?

Nice work. How about a dumb Q from a guy who has to sweat class rules.

If primary head port is 32mm, what is secondary head port size (stock)?

I ask because I'm limited with respect to work in the head, can only go in one inch. That would seem to be enough to take up the 32 to 34mm...

Hmmm... Mo Powah - tasty!

Re: Ported Intake for Sale
 

The secondary head ports at the gasket surface are a hair over 36mm stock - this is where the secondary butterfly valves are and they take up some space so a "bulge" here was part of the design to compensate.

Forgot to mention that I went ahead and opened up the plenum throttle bores to 2.5in so if you have or may get a 63mm throttle body someday you'll be good to go with this.
