    I have just purchased an '87 34' EC Weekender needing new 454's (7.4L) gas engines. Any suggestions for replacements will be appreciated... New 454'w or smaller blocks...??
    I have inboard drives. Many thanks.

    Hi

    I have a 1990 350DA that was powered by 454's. I repowered it with 502's EFI. They fit just fine and it put new life in an old boat. I was lucky to find 2 motors that were still in the crate but a couple years old....sweet.

    Depends on your budget. Ray's re-power with the 502's is for sure the best way to go if you plan on keeping the boat. If you are very budget conscious consider replacement 454 long blocks and figure on new manifolds and risers as well as pumps. This is an easy swap.

    Sometimes here in South Florida you run accross near new 502 take outs from "go fast" boats that you can pick up for a song. Keep your eyes peeled and you could do very well.:thumbsup:

    No way, no how would I consider small block replacements in any configuration...unless they were the new Cadillac LSA engines but you'll spend a lot more than you would for the 502's by a long shot.

    Good Luck.
