    scored a 454

    Hi all,
    Sorry if this has been asked many times before. I just scored a 1973 454 that was an automatic. I am putting it in my 68 camaro and plan on using a 4-speed manual tranny. I know when doing this swap I need a pilot bushing, flywheel, clutch, etc. What I don't know is do I need an externally balanced flywheel? I assume it will be an eleven inch clutch. I also don't know which bell housing I need. This is a fully functional running motor with all the accessories for a drop in and run situation. I heard it run and verified it has the 049 oval port heads . Complete carb to pan including starter and headers, even the fan and radiator! all for $1300. How did I do? Its got great oil pressure, no noises, no smoke., no leaks. new mini starter, new alternator, new MSD and wires.

    Do you have the block casting number? 454s are externally balanced engines from the factory...

    Nice score. You didn't mention what the motor was coming out of, Depending on the original application, you my have to change the oil pan and pickup as well.

    Sounds like a pretty fair deal, yes you'll need a 454 externally balanced flywheel and if you plan on running it hard you might consider getting a scatter shield steel bell housing, ask me how I know. lol.
    If your car isn't a factory big block car and has the original heater core you'll need to swap in a big block core or you won't be able to hook up the hoses, they'll be behind the cylinder head, another one I learned the hard way.
    It's a bit of a pain, pretty much have to unbolt the right fender if memory serves.
    You'll need the correct motor mounts for BBC on the engine, mounts on the frame will work.
    Last but not least if it's a small block radiator you'll want to replace it and use a clutch fan and shroud,454's get real warm especially in traffic.
    Should be a gas to drive, I had a big block 4 speed powered '69 for 14 years, ran a built 427 and several 396's over the years, sure miss that car.
