383 Mopar Street/Strip Motor

The black Coronet that is my race car, was a Nebraska street racer when I’d bought it (see photos in comments). The motor was a fresh rebuild — I was told the parts but I’d be lying to you if I told you I remembered what they were. There were quality though. When the car came off the trailer — I took it for a pass on the highway in front of my house — and couldn’t believe that this was a 383. I swear it felt faster than my high 10-second 451 in the other Coronet.
The motor came out and has been in the shop ever since. I’ve thought of putting in my 78 Magnum — but it is more of a race motor than a street motor.

Race Prepped Machined 340 Block

This is a rare Mopar 340 block that has been professionally machined. It was originally assembled for a customer in Sweden by Diamondback Engines — and when the engine was put on the engine stand, water weeped from a pinhole low in the block. We had another block ready — so reassembled the engine using that block. This will not weep from that hole if 1/3 or 1/2 filled – or had the pinhole otherwise repaired. The pinhole is so small you can’t see it until you put some water pressure to it. It is low enough that a partial fill will cure it. $1800

Race Prepped Machined 360 Block

Machined Block in a bag. Select Mopar 360ci Motor precision machined .030 — ready to be assembled into a 360 or 408ci. $1800

426 (MAX?) Wedge Block w/Caps
This is the block from the 426 (Max?) Wedge that was in the Vitamin C for many years. I’m told that the numbers and look at the clearancing at the top of the cylinders read Max Wedge Block, but at least one person disputes that. It was a .060 bore.
The number 3 cylinder has water dribbling through a pin hole. I was going to sleeve it — but we also found a repairable crack in one of the crank saddles. While it can be repaired for a street engine — it most likely shouldn’t be done for a race motor. Very hard to find block.
$750

Mopar Engine Blocks



I would prefer to sell all of these blocks as a lot — but I will sell them as singles until someone buys the remaining lot. Mostly 440s, but there some 400s and 360s — even a Poly or two.
I don’t have a list with all of the date codes — so don’t ask me if I after a December 67 date code.
You are free to come to my shop and select the block of your choice. $350 ea, $1500 for 5, $2750 for ten
First come first serve
I also have one 340 block that was precision machined .030 — but a pinhole coolant leak was discovered when assembled. It is so low in the block that a 1/3 – 1/2 hard-block would completely seal. I have $800 in the machining and $500 for the block — but will let someone have the block for the cost of the machining.

81 Imperial Motor for Core

In 1989, I went out to start up my 24000 mile 1981 Imperial and I had no oil pressure. I immediately shut the engine off and put the car in the barn. In 1001 — I pulled the car out of the barn and restored with different engine. This engine has sat in the corner of my garage ever since.
Imperials were suppose to have the parts as the pick of the lot — and I would imagine that this would be an excellent motor to rebuild. $350
