    Default WTB 351C Over Transom or water cooled Logs

    Looking to buy a set of OT 351C headers, or a set of 351C water jacketed logs.

    Thanks!

    Tom,
    Thanks for the heads up!

    I am not sure that those will work though. I am looking to adapt these to an GM Gen III LS engine. This is what the LS flange looks like:



    I think I need a set of manifolds that match this gasket:
    It's listed as "Ford 351 Cleveland Intake Gasket for Perf RPM Heads"

    The gaskets pictured above are for an Intake manifold, not the exhaust side. Which ever manifolds you decide to go with you will most likely have to either make a shuffle plate, or I even heard of ppl using Windsor style exhaust and welding new flanges on them.

    Just an observation, the LS flange looks like it could be flipped upside down. If you could find a set of long collector headers that were semi symmetrical, you might have an easy solution.

    EDIT: heres a pic of some shoenfeld chassis headers that might do the trick

    Josh, thanks for the info. I feel like a dumbass not knowing those were intake gaskets. Durrr...

    Anyway, yeah, I've seen those headers from Schoenfield, but I'm not sure they are tall enough to clear the transom. I will have to get some dimensions and take a look.

    Tom,
    I am going to do some more digging to see if those manifolds will work for me. Is there only ONE 351C exhaust bolt pattern? If so, they will probably work, since there is a guy on ls1tech that used those.

    Thanks!

    I'm almost positive there is only one 351c bolt pattern, the 2v and 4v heads had a slightly different port location, but i believe the manifolds above were designed to accommodate either. Thinking about it, you would be better off with a set of 351C logs vs Windsor logs, as the Windsor have very small ports comparatively.
