Title: 350 olds tunnel ram??
Post by: Kacan on August 27, 2013, 01:22:29 PM: From what I have read no one makes a tunnel ram for my boat? Anyone know if this is true or where I might be able to find one

While not a tunnel ram, Edelbrock does make (number 2812) a high rise single plane - Victor - small block chevy's love 'em, I imagine your Oldsmobile will too.
