What are you guys with 383's running. Im looking to install a 383 1 piece rear seal into my 84 vette. I currently have a TKO600 with the 4 plus 3 bellhousing. Will a 168 tooth 11 inch 400 flywheel fit the bellhousing?

a quality gear reduction starter,

the better quality versions of the gear reduction high torque starters tend to work rather well

there are 153 (about 12")
and 168 tooth (about 14")
fly wheel,
but in every case the starter must be mounted, on the block with the correct matching bell housing on the block to correctly contact the flywheel SIZE your using

there was NEVER a factory one piece rear seal 400 sbc so the flywheel or flexplate that fits the original two piece rear seal components are not going to fit.
one piece rear seal 3.75" and 3.80 " stroke cranks used in a 383 will be different, one piece rear seal type

All ’87-and-later Chevy blocks come with a one-piece rear-main seal. This requires the use of a late-model one-piece rear-main seal crank. Starting with the ’88s, most passenger-car engines converted to hydraulic roller cams that required a spider. This is a truck block where the spider mounting bosses are not drilled and tapped, because the truck engine used a flat-tappet cam. These can be easily drilled and tapped to mount the spider for a hydraulic roller cam.
