Vehicle is an 85 S-10 blazer 4WD with 2.8 and auto trans.
I purchased an old (new, never installed and still shrink wrapped in plastic
in the crate) AC Delco 2.8 crate motor. According to the GM paperwork inside
it was reman in 1997 and has since sat. The GM Part # is 12464641. The
sales order from the dealership calls it GM Part # 88961888. Can any one
advise me where to go to verify that it will drop in? Searching and googling
these numbers produce no results.
Standing facing the flywheel, starter bolt holes are on the right or
passenger side of motor, I can't tell about the mounts as I have not taken
it out of the bottom part of the crate, The block casting number is
14072061, head casting numbers are 14054884 (passenger side) and 14054879
(drivers side). Is this an issue that they are different? Additionally there
is another number on the front of the block just above the timing chain
cover, T1219TP0. The number on the timing chain cover is 14024263.
The 2.8 came in two flavors. The FWD block is different than the RWD
block. They will not interchange. The casting number supplied matches a
RWD block and the heads match what was used on the 84-88 2.8 engines in
a RWD application.
