Like the title says, '28 Ford chassis to install 8BA flathead, closed drive. Which water pumps and motor mounts to original frame mounts? Engine hasn't been installed for mock-up but Merc pumps seem too low. Early car pumps? Late truck pumps? Late Merc pumps with riser adapter? Late car pumps with adapters? Thanks in advance,
Easiest and most common way is truck pumps to frame brackets similar to the old standard Hurst A-28's. Set height for the closed drive type centerline by aligning center of crank pulley with the piece atop the front spring mount that pilots the hand-crank. If the 8BA still needs to be rebuilt...note that you can save a couple inches of front length and get some free functional and visual improvements by building with pre-1949 camshaft, pumps, and distributor...the space you save is pretty useful in a Model A plus you get an actually usable distributor.
It usetawas a simple tab from the Hurst mount collection that bolted into a '28-34 Ford frame to replicate 59A type mounts. You want something out at rails that has a hole for the pumps you use and early Ford biscuits, and that gets front of engine to a good height. This is a slightly muddled version from Speedway, too narrow for a stock frame as it looks to be made for a boxed setup:
There are the real ones...they were meant for '28-34 frames, and neatly adapted either '37 up flatheads or late model motors with Hurst engine brackets, like the Chevy shown here. Picture stolen from Little Wing on here.
