    Does anyone recognize a EP66 stamping numbers on a Patrick's camshaft ? The website shows the same .436 lift #'s on two of his grinds, but no codes... One is a 3/4, the other is a E-2...
    Last one, could I use a '54 235 car flywheel on a '59-up 261?
    Thanks in advance for the help, dyno dave

    Found some additional camshaft coding ; EP66 & CWC, thought someone might have a Patrick's camcard... I'll call them tomorrow, but about that flywheel ?

    Yeah, just give Patrick's a call, that should answer that question in a hurry.

    I think you can use the '54 flywheel on the later engine, but the tooth count will be off on the ring gear. You could either put a later 12 volt ring gear on there or use a 6 volt starter. The 6 volt starter will work great on 12 volts if the engine is in reasonable tune and you don't have to crank it a long time before it starts.

    Waldo53, I'm using a 12v system, so OK with a 12v starter & changing the flywheel ring to the 12v count. Am concerned with car & truck flywheel weight differences, anything on that situation ?
    Again, thanks... dyno dave

    The cars and trucks used the same flywheel (with 2 different ring gears depending on 6V or 12V starters) up through '57, which is as late as this on-line parts manual goes. Cast #3705410. I think you'd be good to go with the '54 flywheel.

    You might ask that question on the stovebolt site (stovebolt.com) there's a lot of knowledge about these engines there.
