    What are guys using for a rear main seal for the Tomahawk blocks with a 3" main? I see TA has several seals, both two piece and 1 piece. Is it the same as a 350 seal? Can I use a Ford 429/460 rear main seal?

    Couldn't pull the trigger on the one piece seal. 2 piece from Ta for my build.

    The only seal I have ever used is the Fel Pro Performance seal for the 429 Ford. Part number is 2948. Never had a leak, and they hold good vacuum.
