Wanting to know previous experiences and feelings on using a line bored, and machined as necessary case, as opposed to a new case. Any thoughts on long term reliability? I run a 1915 built on a used case machined by Rimco, and has been fine for 3 1/2 years, but now will be building a 1776 for my sons 71 bug, we currently dont have a case (Thrown rod on the case that came with the car), have access to a used dual relief case for $50.00. This is a budget project, but want it to last, it will see many more miles than the buggy. Should I rebuild the heads?,or just buy new ones? Want to know others experiences. I will probably use a 110 engle cam, and a counterweighed crank. Thanks for any input.

My 1915 was line bored in Tampa Fla, in 1986. I didn't weld behind number 3 cyclinder, just opened it up. Never had a crank or bearing problem yet. I would trust Rimco of anyone, they have been around a long time. When I read the Gene Berg articles in the mid 1990's, I was worried that my engine would give me trouble, and it has not. I credit the tooling and experienced shop for mine. A bad shop could butcher the case.

If the case has never been overheated go ahead and machine it as needed. When the case has been overheated is when they can't be trusted.
