I lost my sheet with all the numbers on my 340 build, it was in early 2002. It is probably pretty close, it doesn't like pump gas. When first built it didn't like pump gas much then I blew a head gasket and when I put the heads back on 2 years ago I must have put a thinner head gasket because it really doesn't like pump gas. It does just fine for putting around close to the home. Yes like AaronK says it's about 372 +/- and it would be cheaper to build it a different way. LOL
