I made my own. The options for a tall deck bbc were limited at the time.

I used the Holley dual sync on MY setup.. makes for an easy plug and play.. no issues..

That is not coasted guard approved ( I called Holley yesterday)

Does everyone just not worry about the UL/Coast guard on these distributors, they have vents and screw down caps already. Only difference looks to be the bottom vents.

Paint the cap blue, have you met a coast guard that even knows what a distributor cap is.

I don't recall if it even HAS a vent.. .

I TRIED to find a slip collar, USCG approved, dual sync distributor and it doesn't exist..
