What The Hell Is A Shucklehead Engine?

You will never guess. So, I am telling you. Its an engine built with a year ‘57 Harley Panhead lower end and year ‘66 Shovelhead heads and cylinders…… You need quite an imagination to do this.

And the reason behind this project is that motorcycle restoration professional Roger Squires from Southern California, likes the looks of a generator lower end, likes the way a Shovelhead runs and and loves the way Knuckleheads look. That’s not all, he is making the left side of the heads look like those of a Knucklehead!

This bitchin’ engine is going to turn heads. Two Shucklehead engines and bikes are in progress, at this day about 75% completed. How much? Of course, priceless. Need to know more? Contact Roger Squires at 310-322-8320 or go to Universal Engravers

    a local shop in town built what we called a shovonuck .A knuckle head top end on a shovel bottom .

    But im liking this one a lot ,love the pan bottom kidney and the knuckle head rockers.Perfect !

    Gotta agree with Roger and HK…love the look and concept. Hope everything works out on the build.

    Looks very similar to the Knovelhead rocker boxes they sell in Germany that bolt right onto shovelheads.

    Cyril. Very interesting. Another good find.

    Looks nice.

    Great classic look

    Didn’t Paul Cox and Indian Larry do this10 years ago? I love it… But don’t think it’s new

    No they didn’t. They just mixed the Rocker Boxes of 2 different engines. Pan & Shovel, i think. The Shuckelhead is a big innovative job.

    @joe and DJ . As far as i remember indian larry did pan and shovel heads on the same motor not just the rocker boxes .I never got why that was cool personally

    That is just pure beauty, I would love to have one for one of my builds. I’ve owned a knucklehead, own a shovelhead, and want a pan. This is all of the best worlds in one. Now how well does it run? That’s my only concern. But bravo!

    I like it. Sure beats the golf bag deal below.

    Most builders wouldn’t include the manual timer, because they don’t understand it, nor the left twist grip and how to keep the cable free-moving. It scares people. Kick-starting scares people. They think a short-stroke motor is going to bite them. And in this case they’d be right, cause it’s a long-stroke Shove with no compression release, only the soulful timer to blend retard and a hot spark.
    This is motor the T.V. build-off guys should use – and give viewers cause to wonder about – something beyond the paint work.

    Extra credit for using the ’36-53 (flat) cam cover instead of the ’54-64 round-edge one.

    In reflection, this type of modification could only come from the (310) area code. El Segundo is within the heart of motorhead “Valley”. No different than major products that emerge from the Silicone Valley (around San Francisco) – because it has the highest concentration of comp. engineers. Same so for the motor-valley. All the ingredients are there for the taking: hot days & cold nights (great for bud tending and wine growers), “baggy short’s weather” 350 days of the year. Mountain & ocean vistas for contrast. Machine speed shops aplenty. People design and work through the night and/or any hours they want.

    This motor could not have been developed anywhere else except (310). Does this make any sense at all? 🙂

    check out the other Shucklehead left side pictures at universal-engravers.

    You DON’T have to be from the VALLEY or have a DEGREE to conceive a mixture of 2 or even 3 engines and make it work, BUT you do have to have IMAGINATION and KNOW what you’re doing!
    A BRIT that used to live in the USA built the ALFA BEAST< DESMOHARLEY and now he's building a bike with a Massoretti V8 with a KICKSTART.

    Wow! Fascinating. I love it when someone comes up with something this clever that works.

    My students have a bike in the shop right now that they affectionately refer to “Franken-Harley”. The lower end is from a ’58 pan and the top end is from a two different shovels from the early ’70s. It leaks, it has alignment issues and …….is not very impressive. I agree that the afore-mentioned marriage of parts is unique and has a certain amount of “cool factor”, but………it takes a large amount of professional mechanical talent and some engineering common sense to make it all work. My hope is that we can convince the gentleman that owns it to allow us to put it back to a period pan. We’ll see what happens.

  19. 19 Kirk Perry Nov 29th, 2011 at 12:49 pm

    Try and explain to the owner that all he has now is an altered piece of junk.

    Conversely, we don’t if the Shuckle runs either, but though. 🙂

    Good stuff, amazing engines, love it.

    There’s a billion people on earth, but only one can make the 1949-1959 fork cups – and that would be Mark Blankenship.
    The cad plated cups w/ races are $85.00 a set, shipped price.
    Get them now before they’re gone. They’re turned by a master-crafter, then plated. It’s a long process and like the 1949-1959 Buckhorn handlebars, the cups are made in small batches with long periods between.

    nice love it good work are you selling whole bikes or just the motor .

    I sent a complete set of new Knuckle heads from V-Twin® to Accurate Engineering • Dothan, Al, to be re-manufactured and modified for an O-ring intake manifold.

    The V-Twin rocker arms had an oil groove in a (Shovel type) brass bushing that emptied near a rocker arm-hole, and would overfill the intake lower valve spring cover’s, when the breather gear’s internally created suction could not keep up with the oil that was returning, down the inside of the push rod covers and back to the crankcase.

    The heads are finished and I’m taking some pics tonight. All you’ll see are external improvements and maybe a list of the parts that went into it, but I think Berry Wardlam’s mods and materials are a held secret.

    Check in tomorrow morning for some pics. 🙂
