49D-24BusCpe Posted July 6, 2019 Report Share Posted July 6, 2019 Two of us spent four days replacing the '56 Power Wagon 230 that was in my D-24 Business Coupe, with a '90 DeVal 265. My DeVal is a brand new, never-run U.S. Navy JG-75 aircraft tug QEC power-plant. It is a Chrysler Industrial IND-32 clone. The block was cast on 6-19-90! I purchased the car during '12, converted the driveline (to a T-5 transmission and a '65 B-body 8.75 axle) during '13, and finally replaced the engine on 7-19. There's still more to be done! 3 Quote Link to comment Share on other sites More sharing options...
49D-24BusCpe Posted July 6, 2019 Author Report Share Posted July 6, 2019 Oh, I forget to mention that it was 12-volted during '14 with a Gener-Nator and a Pertronix ignition! 1 Quote Link to comment Share on other sites More sharing options...

dpollo Posted July 6, 2019 Report Share Posted July 6, 2019 I did not know such an engine existed. I do know about the 265 and you will be very pleased with the performance. Quote Link to comment Share on other sites More sharing options...

Frank Elder Posted July 6, 2019 Report Share Posted July 6, 2019 Since this is an industrial engine and was slated to run in GSE towing heavy aircraft in low speed high RPM duties.......is the camshaft suited to run on the street? Quote Link to comment Share on other sites More sharing options...

DonaldSmith Posted July 6, 2019 Report Share Posted July 6, 2019 Uncle Sam wanted a continual supply of engines for their aircraft tugs, so when Ma Mopar discontinued the block, DeVal made the engines under license from Chrysler. Some of the casting plugs are different, but the important stuff meets spec. Quote Link to comment Share on other sites More sharing options...

Love the battery. Nice details with cloth wiring and cables, hose clamps, SolarSpark and other decals. Interesting place for coil and relays. Only thing I would change are the modern spark plug wires. Quote Link to comment Share on other sites More sharing options...

Frank, Even though, my 'original' camshaft was an NOS industrial one, I knew that wasn't going to be the right 'one' for my D-24 "Super Stock" project. The cam I chose is an Edgy re-grind.

Hi "Chrysler 1941", I really appreciate you noticing some of my 'original' touches. I have several more details that I will be adding, such as starter & generator data plates etc. etc. The ignition wires are actually 'modern spark plug wires'! They are Pertronix 7mm "stock look" wires. All the best, Walt Quote Link to comment Share on other sites More sharing options...
49D-24BusCpe Posted July 7, 2019 Author Report Share Posted July 7, 2019 The DeVal Corporation is a 65 year old Philadelphia based manufacturing firm that primarily does work for the U.S. Department of Defense. The majority of their business is involved with support equipment for military aircraft. During the mid-'80s thru the early '90s they had a U.S. Navy contract to supply QEC (Quick Engine Change) power plants for JG-75 aircraft tugs. These replacements were to be "ready-to-install" engine/transmission packages for these tugs, which were at naval air stations all over the world. These QECs were to be dyno tested before they were shipped to the customer. This contract involved industrial engines manufactured by Chrysler, Ford, and International that were installed in these JG-75s. The 'raw material' core parts for the Ford 302 and International 345 motors were still being made, and readily available. The Chrysler L-head engine was a whole different matter! As many of us know, these blocks had last been cast at the Windsor ON foundry in '59! Chrysler said that they were unable, and could not produce these 265 engines anymore. DeVal suggested that they could easily supply either 225 Slant-6 or 318 V-8 Industrial QECs to replace the Mopar Flatheads. That was unacceptable to the Navy procurement group. They wanted "exact" replacements for their Chrysler Industrial IND-32 265 engines. DeVal told them that their Chrysler L-head decision would be VERY expensive, as they would have to 'reverse engineer' many of the key component parts - and in particular the block. The U.S. Navy said go ahead, and DeVal went on to produce several hundred IND-32 clones, with (YES!!!) 727 Torqueflites. 2 1 Quote Link to comment Share on other sites More sharing options...
49D-24BusCpe Posted July 7, 2019 Author Report Share Posted July 7, 2019 DeVal produced a number of interesting and unique parts for their IND-32 clone engines. Some of these were to support the engine for various different applications. The spin-on oil filter canister casting, was developed so that the engine could utilize existing filters in the military's part supply chain. 1 1 Quote Link to comment Share on other sites More sharing options...
49D-24BusCpe Posted July 7, 2019 Author Report Share Posted July 7, 2019 Probably one of the most interesting parts that DeVal developed for their IND-32 replacement engine, was their very unique intake/exhaust manifold set-up! You can 'flip' it, so that it can be used in either down-draft or up-draft applications. Because of clearance issues, the JG-75s utilized up-draft carburetors. Also note, that a front or back (or both, for that matter) exhaust exit can be chosen. The picture below shows this DeVal part next to a Chrysler passenger car 265 manifold set-up; 1 1 Quote Link to comment Share on other sites More sharing options...

They all have 8-bolt crankshafts. In fact, my swap utilized a 146 tooth 8-bolt flywheel and a P-15 bell housing! The JG-75 tug uses an adapter to mount the A727B or A727C aluminum transmission.

Frank Elder Posted July 8, 2019 Report Share Posted July 8, 2019 If that is a drain plug I think I would replace it with a petcock. I like the idea but still so messy to change........the bypass, the full flow, the adapter pictured here, no clean way to remove them.

For example; # 27 Plate, Converter Drive 2407456 (Flexplate) # 25 Torque Converter 2843239 - A727B Transmission 2843586 - A727C Transmission Walt Quote Link to comment Share on other sites More sharing options...

DonaldSmith Posted July 14, 2019 Report Share Posted July 14, 2019 Walt, I remembered what you told me about the DeVal. The DeVal was news to most of the guys. Good to see photos above of the actual red monster and its versatile accessories. Good old Yankee ingenuity. 1 Quote Link to comment Share on other sites More sharing options...
