getting the correct flywheel
I have a question on a 1989 fuel injected motor. The engine I own is a 460 block ID (D9TE-AB). It is in an 1989 Econoline E350 with an automatic transmission. I want to put a manual flywheeel on this motor. I think in 1989 the engines were balanced EXTERNALLY which leaves me confused on what manual flywheel I can just bolt on and have the engine correctly balanced. Some have told me a ZERO balanced flywheel will work while others say no.I need to know how to have this engine correctly balanced with a manual flywheel. Thanks for any info.
