PART FOUR - DRIVETRAIN - ENGINE
As mentioned, my Coronet had a non original 383 in it when I purchased the car and that engine had seen it's better days, so it was removed and
sold fairly soon after I found a gentleman who had a very nice running 400 big block that he had rebuilt a couple of years earlier. He had sold the
vehicle that this engine had been in, so he had no use for it anymore. I picked up that 400 for a couple of hundred dollars and it served me well
while my search continued for the engine that I really wanted, which was a 1969 440 HP engine found that engine in 1990 when I saw an ad in one
of our local newspapers. A gentleman was advertising that he had a clean, freshly machined 1969 440 HP short block for sale, so I immediately called
him and said I'd be right over.
When I arrived, he did indeed have an beautifully prepped 1969 440 HP engine block that had been professionally hot tanked, checked for core shift,
magnafluxed for cracks and bored .30 over. This blocks matching main caps, steel crankshaft and a beautifully prepped set of standard 440 connecting
rods were also there. He also had a set of 12.5 to 1 pistons, a set of B-Body Hooker Super Comp headers and some other nice performance parts for
sale, but none of those parts were going to work for me, so I purchased just the block, main caps, crankshaft and connecting rods.
The next stop for my new 440 was at my favorite machine shop where I had everything double checked again and some custom machine work done to
the block. This work included opening up all of the main internal oil passage ways up to 1/2" Hemi specs, removed any internal factory flashing that could
pose any future issues, double checked all of the mating surfaces for flatness and cleaned and checked out all of the blocks threaded bolt holes for any
issues. After that, the block was hot tanked again and a fresh hone was performed. All new Mopar Performance brass freeze plugs and various other
block plugs were installed, as were a new set of Mopar Performance camshaft bearings. The rotating assembly was also balanced at this same machine
shop once the short block was assembled by me and a friend.
Here's a laundry list of most of the parts that I used.

Cylinder Head Parts
I started with a set of the factory Mopar "452" style production cylinder heads that I already had in my parts stash and had my machine shop hot
tank them, magnaflux them for cracks, check the mating surfaces for flatness and check and clean out all of the threaded bolt holes. They were
then hot tanked again before having new set of bronze valve guides, hardened exhaust valve seats and a high performance valve job done to them.
A mild "gasket match" porting job was also done.

(8) Mopar Performance heavy duty 1.5 ratio stamped steel Six Pack style hydraulic rocker arm package which also included new heavy duty rocker arm shaft
retainers and bolts.
(9) Thick Fel-Pro head gaskets. (which helped to bring my final compression ratio to the 9.7 to 1 that I was looking for)
(10) Mopar Performance brass freeze plugs.
(11) Older style Direct Connection chromed stamped steel valve covers.
(12) Mopar Performance valve cover accessory set
Oil System Parts
(1) Milodon 7 quart oil pan.

(5) Mopar Performance high performance, high output mechanical fuel pump
rated @ 80 gph.
(6) Mopar Performance mechanical fuel pump pushrod kit.
Ignition System Parts
(1) Mopar Performance electronic ignition conversion kit.
(2) Mopar Performance chrome ECU box used instead of the original orange ECU
box received in the above kit.
(3) Mopar Performance distributor intermediate shaft bushing
(4) Accel 8.8mm 300+ Spiral Core spark plug wires. (black in color)
(5) Two of the Accel 8.8mm Competition Spark Plug Wire Loom and Separator kits.
(6) MSD Blaster II ignition coil.
(7) Mopar Performance high output voltage regulator.
Cooling System Parts
(1) 1966 factory style stock cast water pump housing. (drivers side exit for lower
radiator hose)
(2) Moroso high performance, high flow aluminum water pump.
(3) Mopar Performance 180 degree thermostat
(4) Cool-Flex chromed and ribbed seamless copper upper and lower radiator
hoses with polished aluminum end caps.
(5) Custom fabricated 26" brass and copper radiator with a five row, off-set core
and factory 1966 C-Body upper and lower tanks. (upper tank #2582962, 1966 C-
Body with 383 engine and factory air conditioning and either manual or automatic
transmission) My Coronet's original factory metal radiator mounting brackets
were also used.
(6) Mopar Performance reproduction 67-69 B-Body Hemi and big block 26"
radiator fan shroud.(fits some 66 models also
)
(7) Aftermarket aluminum fan (I would have much rather used the Mopar
Performance viscous fan package that I have used on all of my other Mopar's in
the past, but the thicker custom radiator prevented me from doing so :p)
(8) A 1980's Dodge Mini van coolant over flow bottle was also added.
I don't have any pictures of this engine being built, but here's a few pictures that were taken as we were installing the engine into my Coronet
back in 1991.
