Hey gang need help_____ I bought a vintage Lloyd Shores sprint car I m restoring and cant fit the crank shaft of the stock SBC I m putting it thru the hole in the motor plate. Got the coupler and driveshaft yoke thru ok but rear of crank wont. I m new to sprint cars. Any suggestions would be great. Thanks

sounds like the crank flange has a counterweight on it.

Just a guess but it was probably bored for a 283, so you're going to have to have it centered up and rebored to take the newer crank diameter. Not a big job. Bob

back of crank needs shaved down then rebalance crank just 1 suggestion

What Bob says....You should add your location. You might live nearby someone on here that has a Mill and could bore it for you.

If you are using a stock-type Cast Steel Chevrolet crank you will need to have the crank flange turned down to fit through. We have the same problem with our UMSS Traditional Sprint Car Series engines.

Thanks Guys____Can you cut the motor plate a little bigger to get it to fit thru and will it still fit/turn in the torque ball housing ? Thanks again.

As I noted earlier,tell us where you live. You can do that by editing your profile here: https://www.indianaopenwheel.com/pro...do=editprofile Or you could always post here where you live. You might live close to someone that posts here that has a Mill or a Lathe that could either bore out a motor plate,or turn the end of the crank flange.

Photos are also good if you could take a few. If you could get a few photos we could help you post them.

Or... You can do as some friends of mine in Lima Ohio did. The boys blew their engine the night before an Outlaw race at Eldora. They had an old station wagon with a 400 in it setting out back of their shop. They put the engine in but it suffered the same fate you are encountering. Running short on time one racer yelled to the other " Go get the wrecker Scritchey ! " They pulled the plugs out of the engine and pushed the old car around the building. The brothers stopped occasionally to put some more tension on the engine plate bolts as the hole opened up. Later that evening the ingenious machinist`s got the car qualified, won a heat race and was running up front in what was then the Fram Dash, before a couple of those stock 5.56 chevy rods decided they had enough and went on vacation out through the oil pan.
