Serious brain fart!!! Could it work??? Yall tell me!!!

Pushrods don't explain all the cracked heads and blown headgaskets they had.

For starters diesels need a compression ratio of about 22:1 if I remember correctly.
Diesels fire when the compression and temperature are high enough, not by spark.
Then it would need a (timed) diesel injector pump, which means it would either have to be electronically (computer) controled or physically connected to the cam or crank by gears or chain.
Spark plugs might be able to be replaced by injectors (maybe) but the head would have to have injectors either way.
Head gasket would have to be a monster to hold that compression back.

That's just the big stuff :D

Somewhere between 16:1 and 21:1 Compression for most diesels.

I haven't been inside many diesel engines, but I do know the 2.3L and 2.5L Turbo Diesels I ran in my D50 were right around 19.5:1 - 20:1 Compression ratio, and they had NO Combustion Chamber in the heads. The head surface was flat, only the valves stuck out past the head surface.

For S&G's, here's some pictures of a 2.3/2.5L

Did I mention that little tiny 4 Cylinder weighed as much as a 360? :prayer: And it had 6 Head Bolts around each cylinder.

It had glow plugs, but I never had to use them. Just tap the key and it fired up instantly.

He'd have to find a 6 Cylinder Injector Pump from a Diesel, like a VE44 from a Cummins, or one of the newer VP series pumps off of a Cummins, or one of the older Denso/Bosch Pumps from a 77-79 Dodge Truck (Mitsu 6DR5 diesel), not sure what other 6 Cylinder diesels would have a suitable pump.

The 6DR5 Pump would probably be your best bet, since it was the closest in size to the /6, at 4.0L. The big issue would be keeping it from popping the head off the block. Not to mention, Injector Pumps aren't cheap. People charge outrageous prices for them.
