converting 301 diesel to gas

jaxx fan · Feb 20, 2013

I have read about converting a301 diesel to gas.
What has to be done and when you get thru what are
you gaining or what can you expect from it. thanks
for any advice.

Not my cup of tea as the head bolt hole location in block is different from gasoline to diesel so I don't know what you would do about that. You are speaking of an IH engine, correct.

I am not too familiar with IH diesels but I do know that my cummins has significantly higher compression than a gasser. High compression is what makes diesel combust so, you'll have to do something about that. It would probably be easier just to sell the diesel and buy a gasser or swap motors with a donor.

I have never heard of such a thing, and I have no idea why anyone would want to do that except as a personal challenge.

If you read about it, find where you read about it, find who wrote about it, and ask them. They either know how/why it was done, or who did it. Once you find out who did the conversion you can pick their brain if they're willing to share.

Converting a diesel engine to burn gasoline is not commonly done. You'd have to be a pretty brilliant machinist to do it, with all the right tools and equipment, lots of time, and be completely bored out of your mind.

Why on earth would you want to convert a diesel to gas. The diesel is far more efficient to run. I don't know what engine the 301 has but some of the Perkins engines share the same block. There would be a lot of changes to make.

are you building a puller? one of my employees at the shop ran an olds cutlass drag car with an olds diesel converted to methanol. with the blower, the engine produced right around 1600 hp. car ran the quarter in the mid 7 seconds.

Yes I"m talking about a puller engine and yes I'm talking about a 301 or 283 pre cup I> H> engine. I do know that intake and exhaust are on opposite sides apperaing to make it a12 port engine. whether bit makes any difference as far as flow I don't know My understanding was most parts gas or diesel were the same. I understand compression is quite abit higher simply because it is adiesel. If pistons could be changed to lower compression ? what about head is it cupped or flat? any advice from some that has been there would be appreciated thanks.
