    I am putting a 454 in for a 350 and do not have the motor mounts bolts and want to get the correct size.

    Please share with me the correct size/thread/length or whatever info. I need to go get the correct bolts for the motor mounts.

    TIA.

    To bolt the mount to the engine or the through bolt between the mounts?

    If you're replacing a 350 with the 454 then all the bolts you currently have will work.

    Sorry about NEI.

    I was asking about the bolts/nuts/washers that go thru the the mount not the mount to the engine/frame.

    Just FYI, I don't have the bolts that came off the 350 so that is why I was lost.

    Thanks for the replies.
