Shovester

[SKJOLD]

I have been toying with the idea of putting shovelhead jugs on my motor when I rebuild it. Anyone have any experience with this? What are the advantages and disadvantages? I want to build a bigbore engine to increase torque without sacrificing it's high rev ability as strokers do. I am also thinking of high compression pistons and a large oil cooler with a high volume oil pump to drive it.

Lotsa machine work necessary to the Sporty bottom, and to the Shovel heads. Special cams, rocker arms, and I forget what all else. It's an awful lot of work, and an awful lot of money, for not really any more return than from a big bore Sporty engine.

If'n the bug is chewin' and making you itch, try scratchin' it with one of the S&S Sporty motors. They uselate model cases already fitted out for up to about 90 inches.

Did a little digging. You might try contacting Trock. I don't have a link, so you'll need to do a search. The cases - cylinder deck area - have to be built up with weld so the wider Shovel cylinder bases will mate up. Cylinder bolt holes in the cases have to be welded up/redrilled, too. Don't know if just the cases,just the cylinder bases, or both have to be redone. Since Shovel push rod angles are way different than the XL the rocker boxes have to be machined to accept the new angle and seal up. You can still use stock XL cams, and the stock XL tappets, and the stock FL rocker arms. Not sure about the pushrods as it will depend on the height change from the lifter block/tappets to the rocker arms. Some work has to be done on the cylinder fins to clear the push rod tubes, too. And don't forget the custom exhaust that'll need fabbed up.

Lotsa expense any way you look at it. They do look cool!

Trock Cycles are the experts. Here's an old poster.
