Ford V8 Crankshafts/Bearings
 

Sometime back someone was discussing using C8BA rods and bearings on an earlier V8.

This is ok if you are using a C8BA or C49A crankshaft with two oil holes per journal. If your crankshaft has only a single oil hole in the centre of the crank pin the oil will leak between the two rods.

In Australia, we see a few engines with C41A/C49A crankshafts and locked in bearings. The crankshaft size is the same as the C8BA, but the bore in the big end of the rod is larger.

Bearings oil and other important stuff
 

Absolutely right. When rebuilding a flattie and you are going to use 8BA goodies always be sure to match an 8BA crank with 8BA con rods. This was done when I rebuilt my engine...I used a 1948 Block and 1952 Crank and Con Rods.

Most important.

You can also use a 255 Merc crank in the 48 motor if you use Merc pistons too and you end up with a 255 cid engine. That would give a noticeable hp and torque increase.
