tunnel ram

The problem with a vacuum secondary carb on a tunnel ram is the secondaries don't open until high RPM and sometimes they NEVER open. May as well run a single 4.

The cross mounted carb linkage is not that complicated.

Like I said, too small with other issues, like no metering blocks in the rear, if they are 1850's. We are not even sure he don't have something like a 450 that were used a bunch and never worked worth a damn.
