Evening all;

I am new here and actually looking for a specific piece of information. I have a mid engine project car that currently has an SBC 350 mated to a Porsche 915 transmission through a custom adaptor, flywheel and clutch setup. I would like to see if I can swap in an LS while using as much of the adaptor as I can (adaptor plate, clutch and pressure plate) and make a new flywheel with the correct dimensions for the LS vs SBC.

I would like to ask if anyone that has an SBC out of their project is willing to take a measurement from the crank face to the bell housing mount surface. I don't know for sure if the SBC has different crank face distances between the split rear main seal or solid main seal.

Thanks very much
Don

A quick image of what I am asking for.


Also a couple pics of the flywheel setup for reference
