    I make a new thread on this topics as it is related to early Hemi, adaptors, Lasalle transmissions dito.

    If one read the early Hemi ( 392 ) has a 172 tooth and 14.64” diameter std.

    -I do has a older aluminium flywheel at 143 tooth.

    I guess few or non know the old adapters from Cragar, Offy etc how starter was mounted, maybe the idea was use the std plate ?
    As far as I see its require 3 adaptors (?)
    If so I guess it will not work with a 143 tooth.
    Maybe that was for the earlyer models pre 56 or even the long bell 331 or even earlyer (?)
    It cant be that uniq has a stick early Hemi vs hotrodding, racer.
    -Ideas is shore welcome.

    I believe that the early hemi flywheel had 146 teeth.

    The Cragar/Offy adapters are essentially identical. The Hemi to Cad/LaSalle adapter was designed in three pieces: Hemi starter plate (part no. 400), Hemi to early Ford (part no. 401), then early Ford to Cad/LaSalle. The starter plate moves the starter to the passenger side. Either of the two Hemi flywheels will work; you just need to match the starter and flywheel. The pictures show how mine went together.

    Another adapter option is the Tran-Dapt Hemi to Cad-LaSalle. It has the starter plate and adapter in two pieces and uses a lever to actuate the throw out bearing. 100_1224.jpeg 100_1223.jpeg 100_1222.jpeg

    I read in the book 'Chrysler Hemi' by Ron Seridono at page P102 that its 3 adapters.
    First the factory adaptor ring #1613713, then Chrysler to early Ford, then early Ford to Lasalle.
    When I search on that std ring on internet it look as the ones I has here. Not thick.

    As Tdesto276 show its a Chrysler std starter plate ( 400 ) but it don't look as the ones in book, or I has, what he show is way wider (?) plus se picture in the book but it's said its the 1613713.

    This was my high school grad present in '67. B&M sold these to adapt the long bell 331 hemi to a Dual Range hydro. Came with the aluminum adaptor and hydro flywheel. Vary rarely see one pop up on ebaY.

    I think it will be almost impossible now soon 2026 to find this 3 adaptors shown in the book or what Tdesto276 show/has using a Lasalle.
    If now std 32 frame ( I has not decided cross/rearaxle ) or top or sideshifter ( sideshifter is cool and less expensive but will not work with std cross.
    I might found a Lasalle 37 with rear modify for TQ tube std but if change my mind to a Olds rearend ( open driveshaft ) its not easy fix that.
    So if do this and use tge TQ tube/std cross best is to find a early Ford to Lasalle adapter.
    That will not be easy either today but…then make a own ring to the std Chrysler starter plate ( reverse it so starter to passanger side )
    Then an 14.65” flywheel correct set to fit bendix in action.

    Hello,

    A lot of the early hot rod/drag racers from the time Howard Johansen started making his cams/kits and other hot rod motor parts, he did make aluminum flywheels for all motors, starting with Hemi motors. We built a 283 SBC motor in 1959 and made it to a larger full blower spec parts motor to 292 c.i. a few months into 1960. We added a 671 supercharger and a new Isky-Gilmer Belt Blower Drive and Edlebrock manifold to the SBC motor. Those kits were not available to the general public until several months later.

    Howard’s Cams. In addition to building his first cam grinding equipment, Howard Johansen also created a variety of engine components including fuel injection systems, aluminum heads, forged aluminum connecting rods, and aluminum flywheels.

    Here is an advertisement from 1961 for all of our hot rod/drag race parts to be sold:
    upload_2025-10-29_5-22-47.png
    Sorry for all of the typing errors. The newspaper typist was not thinking as she typed what I was telling her. 292 c.i. motor, port/polished heads, Reath Crank, 56 Chevy Positraction 4:11 and not a 49 Willys Motor, but a running,1940 Willys Motor.

    As far as LaSalle Transmissions, ours was a used one we picked up from a salvage yard and was totally disassembled back to full action. The stick lever worked great and for the two years we owned it, many a speed shift was done quickly and powerfully with no after effects. We also used a Howard Cams Racing Aluminum Adapter for our motor/trans connection.

    Check out the Howard Cam Company wares. It may not be the same warehouse, but the name might still be active. YRMV

    The letters match the engine, the numbers match the trans. td1.jpg td.jpg td2.jpg

    Ah, so ND is 58 and up B engines.
    Not Hemis.
    One could guessed they used the same.
    Maybe that fit ex a 440, or later Hemi then.

    Great to solve that case on that adaptor, thanks !

    I has call Wilcap, but I guess my demand is not that common today.

    I has to think this over how I like to set-up the chassie and components.

    The deal is to find the Offy or Cragar adaptors 400/401.
    ( then no std Chrysler plate is needed )

    -If anyone hold on to them, give me a call.
    Then its just to find the adaptor to early Ford to Lasalle.

    I guess I found one down the road, but I guess its will be hard get this 3...

    The flywheel I has is a early Hemi Scheiefer 700 ( No ; 311 sp ) and I guess at 143 tooth it might not fit that adaptors, or ?
    Next question, if, what kind of starters fit that 400 adaptor ?

    -This flywheels, how is the experiance of them, easy to split (?)

    I think the 1957-58 12 volt starters fit that match the 172 tooth flywheel from what I recently read.

    So say I’m get the adaptors 400/401 they is for Chrysler starters.
    So even if the 143 has the same diameter as the 172 it might not work.
    -One Hamber actually contacted me and had this 2 adaptors ( Cragar ) and maybe the 3’d and I asked if my Scheifer 143 tooth flywheel will work and if I got his answer correct it would.
    Ideas ?

    I did ask him on the time era in hotrods on use a 1958 392 in a Ford 32 chassie and use Lasalle and the TQ tube early Ford resr axles and if they used it ca 1959.
    His answer was, that was a classic set-up back then, but if so for street ( rods ) but not for dragracing ( of course )

    Need to match the starter with flywheel. If the diameter is the same you'll probably need the 1956 and older starter to match and I think they were 6 volt?

    Yes noted this, Chrysler had the 6 volt had 146 tooth ( my Scheifer flywheel is the 143 tooth and its for a early Hemi (?) and in 1956 on the 354 it become 12 volt starters and 172 tooth.
    One ’can’ use a 6 volt to 12 ( I read )
    They do sell new hiTQ starters both 146 and 172 ( 12 volt ) but case is ….I has hard for new stuff made in China.

    Hard to see it is metric.
    Chrysler used 143 tooth 59-79 and ex 426 Hemi used 143 tooth so its not unusual, but this flywheel is to a early Hemi.
    I has try to sesrch on part number but cant find anything.
    Ok say Scheifer made several ex 146, 172 ( std early Hemis ) and maybe other tooth numbers (?) and this 143 but why as how to get it to work with a starter/adaptor ?
