340 Intake Manifold Casting# 2531915 - Upgrade

I'll be the first to admit I know very little about OEM SBM intakes. That said I need some input from the small block crowd.

I have a older friend that has a 385" (360) stroker in a 67 Valiant Signet, Purple Strip cam, ported heads, AVS carb, and a ported iron 1969 #2531915 intake.

He's told me for years that it's a great intake once ported, but I tend to think there has to be a better option in aluminum that will still fit under the hood with a OEM air cleaner.

The other issue is he tends to be very frugal and uses what he has rather than spend on the latest and greatest. I've driven this car several times and you better make sure you have it

pointing straight before you stab it to the floor. This car can be a real handful to drive. After 15 years of use it's time for a refresh this summer and I thought I would by him an aluminum

intake to go back on it. So what aluminum intake would you replace it with that would be an improvement in port volume and yet still fit under the hood?

Thanks.
