Modify Diesel head for Gasoline?

[SpeedMan]

Ok, so I have maybe not thought this all the way through.. But an idea I think about now and then.

Diesel head, sink the valve seats, Diesel has more deck thickness? Make your own combustion chamber, probably a nice compact one, probably with a dished piston, but I guess you do want to try to get most of the combustion heat in the chamber and not the piston?

Put a sparkplug where you want it, but realistically where either the injector or glow plug already is.

The prechamber, too hard? Troublesome to modify?

The more I think of it, the harder it sounds to do, the less I think about it, the better the idea sounds...

I hope your talking about a light weight 4 cylinder Diesel in a car, otherwise I think the whole exercise is a waste of brain power.

Pulling tractors add a dist and spark plug to run on alcohol, pretty standard practice with the pro stock class.

Have done a went a couple different ways for my NA engines I builds for pulling. The first I did was a heart shaped combustion plate between the block and head. The rest were a dished piston with valve reliefs.

Really cool, sorry for the reeeeally late response, and thread resurrection, but I would not feel OK with not saying thanks.

Thanks, the plate was smart, I thought maybe dished pistons would be the easiest route. Do you make D282 engines? Do you machine new precups and put the spark plug there? This gives me more ideas than I have time and energy for.. Haha..

Yeah a long time ago that D282 was built over 20 years ago, sold and retired to a street strip fox Mustang. A guy that live near Indianapolis who use to do all Indy Cylinder head iron repair welded up the injector holes and drilled and retapped for spark plugs. The plate worked ok, it created alot of heat as it was steel and shrouded the valves, the dish seemed to work better for these 2 reasons.

Here is probably one of highest rpm runs at 6700rpm.

Really cool. I will try to get some hands-on info and try some stuff out. I also have been starting to wonder how hard is it to cast my own head too, but I sometimes like to think a bit too much about stuff, it is also much easier in the mind and on paper than to do it with the hands, and not least have the equipment to do some of it.
Thanks
