I found 3 used LRG 425 engines in the Michigan area for $850 a piece. For those of you who are not familiar with the LRG engines, they are Fords heavy duty version of the 2300/ 2500, which are used in industrial equipment. They make great racing engines and feature a unique oil pump which is not prone to failure like the standard 2300/ 2500 engines.

Yeah Mike, no one really talks about these motors, but they are probably the best of the stock engines to work with. They come in both single and dual plug configurations. The engines I have measured, seem to have slightly thicker walls and webbing within the block. The oil pump housing sits where the aux shaft normally goes and the oil pump drives directly off of the timing belt, eliminating all of the other drive apparatus for the pump. No more broken distributor gears with this set-up.

I am building an engine for road racing, using the 425 bottom end.

The LRG425 engines are configured for a crank triggered ignition, but like anything else, you could always adapt a distributor to run off the crank. I am adapting a distributor to a Lincoln 3.9L engine, that a friend of mine is swapping into his 65' Ford truck. In my case, when I build up my next engine using the 425 block, I am going to drive the distributor directly off of the auxiliary shaft. I have done this before on dual plug engines, using a Nissan Z-24 distributor.

I just threw this out there in case anyone was considering a racing engine build, where you would be more likely to shear off the oil pump drive components.

Do you have any information how to adapt to run a distributor? I have a LRG-425 that has a hacked up ignition system and wiring harness. I would like to convert it to a distributor and carb setup.
