Yes the project is still going! Had some slow downs and changes of plans, but a very hot 4-53 with lots of boost is still going in a square chevy. I've hit the point in life where a regular cab truck didn't make a whole ton of sense anymore with a daughter and pooch, so I sold the red chevy. To replace it, I picked up an 82 k30 454 4spd truck from california with 110kmi and all original minus new carpet, headliner, and 88-91 grill swap. My compound turbo vw diesel swapped ford ranger has become the wheeling toy, so I no longer needed a dual purpose rig, I need a straight up hauling rig. The truck runs and drives as is, I'm going to try to build the 4-53 over the winter and get it swapped in on mechanical power. Once I get the motor in and running, I will do the ddec conversion.

Here's the new recipient

Some buddies showed up last night, some beers were opened, that led to the shop getting reorganized, which led to the detroit getting pulled out and worked on :D.

Crank plastigauged right at .002" and spins like a dream.




Need to get make a trip for stainless bolts for the front cover, oil cooler, and air compressor brackets. Slowly but surely!

Nice to see you working on it again.:)

Collecting more oddball parts, I was able to track down a starter drive for my air starter. Figured it was a good night to crack a beer and mess with it. HD starters all run the same mount pattern/ring gear offset, you just change out the pinion gear to match your ring gear. I needed to swap to a 8/10 pitch 12 tooth gear according to the chart from Ingersoll.

The man, the myth, the legend Wayne himself came out this past weekend from NY for the semi drag races at Onaway. He brought a few goodies with him for my project and assisted in getting the pistons/liners in the block with the oem setup tools.


Wayne had a run of custom flaps made, so naturally a set will end up on this truck


DDEC 4 8V92 ecm that Wayne reflashed to a base file for a 350hp 4 cyl with 3400rpm limter.


Set of 4 dyno tested only injectors from a 550hp 8v92 to get it started on while Exergy builds my big injectors.


DDEC 4-71T engine harness


Since half the reason anyone does a Detroit swap is to have Jake brakes, they're definitely going on. However, I refuse to pay ~$1k/cyl that they sell for. I bought a 3 axis cnc that's due for delivery in the next 2 weeks, so I'm going to make some. Wayne was kind enough to leave me with one master and one slave to measure up. If they made these things back in the 50's, absolutely no reason they can be re-made today in a cnc and be made publicly available for affordable prices.


Lastly, Wayne helped get the pistons/liners assembled and dropped in the engine with use of his special tools be brought out.
