With the machine work done, it was time

to start engine assembly

1967 Cooper

We used ARP assembly lube on

our new main bearings

We took our block, stock Cooper S rods and crank to Gerald and Charlie’s Auto Machine Shop in Sanford, Florida. This is a good, local shop that prices their services very reasonably.

They handled all our machine work for about $300. This included boiling: the block; resizing our rods to make sure the journals are round; checking the block for flatness; boring the block .040 over, and installing new cam bearings that we got from APT. The crank was also checked and machined to accept .010-inch oversize main bearings.

All in all, our Mini engine was in pretty good shape and was very original. Next we will take a look at the head and cam.
