    I know I'm being lazy but I thought I'd ask. Anybody know off the top of their head what size the two bolts are that hold down the fuel pump in a 455? I need to pick up a pair for an engine I'm putting into my car.

    Off the top of my head, I'm thinking they're 5/16-18 by an inch and a quarter?

    Eh 1/8" tolerance is acceptable in my field of work, not too sure in a motor tho. ;)

    Bigpig455 Fastest of the slow....

    The good news is the fuel pump mount doesn't have blind holes

    Theoretically too long a bolt could be very bad. But 1/8" is probably not a problem here.
