    Default Unique Shovel

    So I did a search but couldn't find anything. Anyone know anything about shovelhead cases that the cylinders are cast into the case? The Bottom of the case opens up instead of splitting sideways.Click image for larger version.

    It was made by Nostalgia Cycle (no longer around). I've only seen pics of a few over the years (like 10yrs ago). I don't remember anyone having nice things to say about them.

    I think it was an 82" motor? It was something out of the ordinary (80", 84", 86" motors) size-wise. As you mentioned the cases split horizontally and the cylinders are part of the cast aluminum cases.


    One thing I never could wrap my head around... How the heck do you put new pistons in it? I mean, you obviously have to split the case horizontally but how can you compress the rings and push both pistons in at once? Seems odd to me. Maybe you can get them in with both at the bottom of the stroke but it "seems fucky" to me and removing the crank to do a top end is silly.

    The weird thing is the only info I can find is negative towards the company now that your gus gave me the info to search. No one has any experience with the actual engine. (Except one guy who said he had one and it ran great)

    Sounds like you are talking about the "Super Vee." Big thing I remember was that their big selling point was that a good portion of the internals were Chevy small block V-8 parts.

    Yes I remember that. I think they used 350 4" bore pistons. Kind of a minor deal to me, but neat I guess.

    It's not a super vee. It's a nostalgia cycle shovelhead 82ci as boomboomthump stated. Talked to a guy who has ran one for at least 8 years and never had it open. I think I'll go for it. The company may have been shit but I don't have to buy parts from them so who cares...

    From what I was told hopefully I won't need too. The biggest thing I haven't considered until now would be the head bolts. What they're torqued to? If they are special bolts? Will I ever keep the head sealed?

    It's a cylinder head. Why should it not seal? Plenty of motorcycle heads and many millions of auto heads are bolted to aluminum blocks. The Honda CX series is a successful example. Bonus is aluminum cylinders are more similar in expansion rate to the aluminum heads.

    Special bolts are more work to source so unlikely, but the world is full of fastener options and if you need to machine something different, so what?

    The horizontal split crankcase is a very good idea which is why it's standard in the motorcycle industry.

    I'm only concerned with whether some one had replaced said fasteners (if they were a special tinsel strength) with a standard bolt. Figuring out exactly what strength I needed doesn't sound appealing.

    Unlikely someone would swap them out. For what reason do you think that was done?

    Special strength? Grade 8 should be fine if you are worried and want to replace them because the heads may not look like whatever it was you expected though I'm not sure why you expected it.

    People who spec engines for production don't want to pay for lots of weird fasteners.

    Use Grade 8 if worried and ensure proper thread engagement. Lots of threads on that. Here's one from my favorite machining forum:

    Nostalgia cycles super vee were 93" motors. A lot has been written on them and an extensive series appeared in either the early THBC mag or late IH. IF that's a Super Vee. I don't know about the other shovel motors they may have sold but all bolts have a torque spec. . As far as head bolt choice ( if they fit ) you may want to look into the ones they used on Evos. They were a one shot " torque to yield " bolt. They were used on all aluminum motors if that's an important detail.
