Hello all, I'm in need of a small block 2X4 high rise intake for a 350. Motor year is '80 (last yr of 350).

Wondering what options there are out there as I have discovered a twin high rise for this motor seems to be a bit of a needle in a hay stack. I have discovered the Offy 5706 but they only cast them after the have a half dozen orders or more.

Aside from that I haven't been able to confirm another twin 2X4 high rise that fits a small block olds, pretty much from '68-'80 in the 350.

I have to believe there's some other options that will work. I've looked on jegs, summit, and whitney just by the motor make and size.

So if anyone knows of some other high rise 2X4 that will work please reply, and thanks to all.

 

There are not.

Short of a custom-made sheet metal intake, the Offy is the only dual quad intake available for the SBO. It's a flat single plane intake, so you'll be using it for show. A good single 4bbl will make more power. Used ones show up on ebay from time to time.
