The motor arrived set up for dry sump. We are going to go back
to wet sump. Here I'm fitting a Stef's oil pan.

The rear main caps interfere.

There is no interference at the front.

The head stud kit is standard 7/16"

Some of the bores are out of round and with a great amount of taper.

The cylinders will need to be bored and honed.
I have a rough mesurment of 4.165" bore. The crankshaft
is 4.000" stroke and using a spare 6" rod with 1.125"
compression height piston as a gauge I get 9.125" block deck
height

Just a quick photo of the SCAT crank storage rust.

This Donovan 400 block has SBC 400 mains and so the previous owner
used inserts under the main bearings to fit a SBC SCAT crankshaft
with 350 mains.

SCAT crank is now in a Callies box and will be shipped to the
original owner.
