Dude, I don't understand. All of the 400 small blocks I checked on rockauto have starters available for like $50. What did this come out of? I know I have bought starter(s) for a 400 before at the local parts store and they weren't $800.
every stock 400 has the big flywheel- he needs a starter for the small flywheel.
the only reason this is complicated at all is because the small flywheels use a starter with a straight across mounting pattern, and the big flywheels use a starter with offset mounting pattern. this is due to where the starter drive gear winds up in relation to the mounting bolts.
most small block and big block V8's and inline 6 cylinder engines from the early 60's to the late 90's are drilled for both patterns, but in the mid 70's- probably as some sort of weird cost cutting measure- GM didn't machine some 350 and 400 blocks for both mounting patterns. it's really just a single missing hole that needs to be drilled and tapped, but it needs to be precisely located and drilled with an unthreaded shank that is the right depth for the knurled part of the starter bolt to engage to keep the starter properly located.
