    I’ve got a spare model A frame, a good 235 and a rear model A axle. Was thinking of doing a TROG rail. What’s my options on the 235 to the model A rear or am I better off doing something else? Thanks

    It's almost as if they are saying ' traditional hotrod' only.

    It’s almost if one should read the rail class rules and not the OHV class rules. ;) Acceptable engines are, FLATHEAD 4 cyl, FLATHEAD V8, STRAIGHT SIX and OHV 1949-1954. Last time I checked the GM straight 6 was being made even earlier than the ford flat head.

    For the OHV class not rail/drag.

    https://www.theraceofgentlemen.com/entry Oddly, while the rules specify the trans and rear for early OHV they don't say anything about drag/rail.

    DRAG/RAIL: All Entries must use stock model T or A frames only. Homemade tube needs to be submitted for approval. You can not lengthen frames over the stock FORD MOTOR COMPANY length, you may shorten if you wish. Early homemade tube frames will be accepted. Wheel base or front and rear axels may move or be altered in either direction. Acceptable engines are, FLATHEAD 4 cyl, FLATHEAD V8, STRAIGHT SIX and OHV 1949-1954. No bodies or tin is allowed in the drag class, only a small firewall if desired. Roll bars must resemble safety bars of this era. Square bars, round tube only. No full cages or roll bars made from exhaust tube.

    EARLY OHV: Engines 1954 or older. All makes USA. All cars or trucks will need to be hopped up, cut down or customized in a traditional late 1940s to early 1950s style. Transmissions: 3 speed Ford ONLY, Ford banjo rears ONLY. Bodies up to 1941 (exception for this class only). No modern wide slicks unless pre-approved. More modern years can be submitted for special consideration.

    So back on topic:). Is there a 235 to Ford transmission adapter the OP can use, or can say a GM transmission be adapted to the Model A torque tube?

    Hmmm, so let me get this straight...if you had a cut-down 29 Chevy roadster with it's original OHV 6, you would have to convert to a 3 spd Ford transmission and banjo rearend?

    Model A rear ends are weaker than later bajo rear ends, but on the sand it probably won't matter 'cause you can't hook up anyway.
