Post by zacman » Tue May 18, 2010 8:06 am

on drivers side of the block: 2468330-2
R.L.
8-16-65

on block by base of distributor/dist. clamp: BH/426 (with a weird shaped cross next to it)
1-7-10

other details: has a 1x4 alloy, rough, painted intake manifold. racing oil pan is missing, told it was replaced by a stock pan for ease of shipping cross country 30 years ago.i can pull valve covers and oil pan for pictures or for more numbers. i just need to find out exactly what this engine is, been sitting under the workbench on a dolly for 25-30 years now.

it looks like a production hemi from 1966 .that year having no VIN stamped on them stops us from knowing what model or body style it in came

R.L.24 68330-2 this is a Standard Hemi number used on all Hemi blocks cast from 1964-71
8-16-65 actual casting date
on block by base of distributor/dist. clamp:
BH/426 1-7-10
the B is the year code 1966 installed in a 1966 body
1- The first number is the month
7- The second number is the day of the month
10- The third number is the build sequence for that day. This example engine was the 10th built
(with a weird shaped cross next to it)
that's Maltese cross signifying a .001 undersized crankshaft
if the cross is follow by the letter X then it has a .010 undersized crank

other details: has a 1x4 alloy rough, painted intake manifold

this can be a single four NASCAR intake for short track racing. the other style is known as the bathtub in which the carb sits down in a tub rather than normal height like a conventional intake

thanks for the info!! also, last time the oil pan was off, one of the cylinders had been sleeved, don't know if that's important or not.

------------------------------
If it's got a sleeved cylinder, the engine was run at
one time, hurt and then repaired. It wouldn't have
come from the factory with a sleeved cylinder.
