I've got a lead on a 6.5 MFI diesel (non-turbo..for now!). I want to put this in a chevy C60 I have, but I'm not getting a transmission with it. I'm looking at a 5-speed OD manual from an '80's Chev C65, and I need to know what I need as far as a flywheel. 1) I've been told a 6.2/6.5 has a different bolt pattern from a SBC, so I take it the flywheel that came off of an SM420 in a '67 C30 I parted out a while ago won't bolt to the 6.5 crank? 2) are the 6.2 and 6.5 crank patterns the same? 3) are the flywheels between a 6.2/6.5 with an SM465 and NV4500 the same? 4) anybody have a manual 6.5 flywheel FS?
