Building the Lower End
November 6, 2012
The guy we bought the Mini from
sent us this photo
With the machine work done, it was time
to start engine assembly
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.
