so...dont look at me sideways when I ask this, lol. I have avoided aluminum imtales because my only experience with them is that they heat soak and cause vapor lock when hot.

is there
A. an iron square bore intake with performance akin to the edelbrock?

B. an aluminum intake that wont have issues or a way to avoid the heat issues?



Exhaust cross over in the intake is your issue. The Edelbrock RPM AirGap doesn't have one so that wouldn't be an issue. Or you can block it off, I used JB Weld to plug the ports in the intake and it worked for years out here in Texas.

I ran an Edelbrock Performer carb on my stock TQ intake for years, it bolts on with a thick spreadbore base gasket and longer studs. No need for an adapter and since you already have one, I'd run it.

You build is very close to what I did to the 360 I put into my 87 Diplomat. Except I ran J heads for a while then 302 castings for testing. Same cam. With the 600 Performer I got better mileage and less top speed, with the 750 Performer I got better top speed but less mpg. the 600 had better response.

They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.
