    No you must size it. Just buy the seal from Zoran at ZOX race carbs. He has a jig to size them. He supplies the seal and instructions on installation. I have used quite a few not one leak. Rope seals are no good due to no asbestos any more so they just burn up on starting eng

    The only thing that would be costly would be taking the block to have the rear seal section line bored, a machinist could make the seal adapter itself in a short time...

    Thats what I was hoping for...its been 3 years almost since the LAST start up of the car after lunching the thrust from one starter rotation I dont want to have to pull the engine out and strip it AGAIN at least for a few years...

    Easy to machine the adapters up then cut them in half, which i imagine could work ok. TK's adapters however are cut in half and then machined up. Way more difficult.

    No, it needs to be trimmed to size but easily done and, no machining of block or crank necessary.

    Iím using the double lip chev rear main seal the block was machined and so
    was the crank as it had to be turned down to a chev size also eliminated the
    knurling the cost wasnít as high as youíd think but it was done with a 4 bolt
    conv ,bore hone ,deck ,crank polish so I figured Iíll use a vac pump in the
    future so why not .

    Iíve had ropes and Iíve had the Buick v6 they havenít
    lasted very long whether it was due to the rope drying out between racing or
    the knurling chopping up the Buick .

    The machining is a little different to TKís as the adapters are pinned in place
    I have pics if needed by anyone .

    Yeah the first set I did were perfect...unfortunately the oil pump even though full a petroleum jelly STILL managed to not get oil pressure. ..so either its from no oil pressure or a bang ip job on the 2.5hrs of trimming and checking...lol.

    Lewis engines have a quick video on youtube showing the chev rear main conversion and what he does to prepare block/crank etc, seems quite simple. I will be calling them soon as i to have had failures with the rope and neo seals so the chev conversion will be my next step.
