If you can find one , it's no longer made , that intake is an alum copy of the 70/72 factory 4bbl and should clear air grabber using the stock 383 base.

Also look for an Ebrock DP4B, that is a tad taller than stock but it clears , I run one on the 383 in my 69 bee with airgraabber.

I also have a stock 70/72 Iron intake that's bee acid ported that I got off a board member that got it from a stock class racer.
