Truckedup,
Go for it, and take lots of pics. Hey guys, the '53-'54 Vettes ran with three sidedrafts and they did alright. I think three are right for a six, I have a new Offy 3x1 manifold sitting on the living room floor just waiting for cruisin' season to slow down for the winter.
I just hate to cut the firewall flange to clear the back carb and linkage. Anybody had any experience with this problem? Oh, by the way, right now I'm running a 2x1 Offy intake and a set of cast iron Fentons (14,000 miles and climbing) so I know a little about multiple carb problems.
