    Default EFI or Carb?

    I am thinking about building a 502 motor to go into a 24 HTM. I am looking to get as many peeps opinions in regard to go EFI or Carb? What are the Pros and Cons of each motor? What I would like to have is a reliable turnkey motor. Thanks.

    If I were building it would be a no-brainer for me. FI, makes starts easy and running at different altitudes easy, no doubt.. But if I were to run at 1 basic elevation, I'd run a carb for sure. Much simpler and cheaper.

    Whatever money I'd save in avoiding the FI, I'd dump into extra cubic inches, of course..
    Is it just me or are toilet seats getting smaller?

    EFI

    fuel mileage, reliability (some will debate this, but I have run many carbs, and none have come close to the reliability i've had with my efi BBC in my boat), longevity, cold start, hot start and any kind of starting you can think of, slow speed, part throttle.....way better! and in my opinion (and depending on the setup) easier diagnostic, less problematic, never ever remove another bowl, change a jet, adjust a float....all that crap...out the window. just type on a computer. also, like on my old engine and the new one, complete electronic ignition control also incorporated (most efi setups do this now). So you spend much less on ignition setups and get better control and distribution, also gives a wide range of possible ignition setups you can run. also, the things i like about efi are the fact its unique in most boat applications, often has a different appearance then the 4 barrel holley.

    biggest downfall arguments you will hear agains EFI are: 1. Too expensive (if done right with budget in mind, can be very comparable to carb)
    2. To complex, if you know nothing about efi and are expecting to have someone else do the entire thing, then both of these may be completely valid. a little working knowledge and/or some diligence on the comp. or reading some good manuals, you can be well educated and eliminate both of them as issues.

    as if it wasn't expected i'd chime in

    Yeah-- knew you'd be along shortly.. lol.

    Note to AP: Some of us didn't go to tech school-- or have everytool known to man-- Or work on Uro-pee-n cars for a livin..

    Some of us just want to go boating simply, cheaply and quickly..

    p.s.. And some of us have a boat tool box that consists of a hammer, some duct tape, a paddle and a twinkie (For survival--just in case I gotta spend the night out in a cove somewhere..)

    Hey Neil
    You don't have to got to tech school, have specialty tools, or work fixing fancy cars. You just have to raise one of your kids to be your boat tech guru. Worked for me.

    Carbs are sooooooo 2005.

    If I had to do it all over again, it would be fuel injected instead of carb if you can afford it.
