BB Tunnel Ram Setup

[VintageMusclecar]

These carbs appear to be early Ford 1850's at a casual glance.


These appear to be newer 450 cfm mechanical secondary units.



These appear to be GM 850 vacuum secondary carbs (converted to mechanical secondaries obviously) as evidenced by the fast idle cam studs, the two mounting bosses for a choke pull-off and the shorter 850-specific choke towers. I'd guess them either to be 3418's or 4054's as the diaphragm links are clearly visible on the secondary throttle shafts and there are no secondary accelerator pump levers as would be found on a 4296. The throttle levers look like `67 style components which would indicate the carbs are 3418's, but I can't say for sure w/o closer view.



I can't recall ever seeing a 4150 carb with Cathedral bowls mounted inline on a TR as these are...noting the side-hung secondary bowl that's been adapted to the rear of the front carb...interesting...
