Decent Slant 6 carb, intake, header setup

I sourced an inexpensive 2bbl plate adapter to transition from a Super Six 2bbl intake to a 350 cfm Holley 2bbl.

I did have to use a burr bit to smooth the port transition between the parts, but it was a perfect size carb for my Slanty. I did have Dutra Duals, the smaller Dutra spec'd cam and some head work.

I tried using a Holley 500 cfm 2bbl, but it was lazy ot low and medium rpm. Once it started to rev though, it mad more power. Not practical on the street with the freeway oriented gears I was running.
