I read on another board they could make a 429 ci gas stroker motor out if a 6.2 diesel.Does anybody know anything about this or is it just urban legend?? Could they be talking about the old Olds deisel engines??

6.2 stroker motor???

The Olds gas engine was converted to a diesel engine so i know you can go backwards on that but a 6.2 Diesel engine to gas isn't going to happen since there isn't a gas head that would bolt onto that block.
But why do you need different heads? Can't the compression be lowered with pistons or a crank? I'm not sure how you get to 429 ci from about 380 or why it would be worth the effort vs. starting with a stock 454. The 6.2 block is really heavy.
Diesel engines don't use spark plugs so a head with a provision for a spark plug would be needed.

It's been a while since Ive seen one with the heads off but that's what I thought.They were "supposedly" get the 429ci by boring it 60 over and stroking it.Their was never mention of what kind of crank or rods were to be used.
This is probably like the thread about boring the 44 housing's

A friend of mine is an olds junky.........he did tell me a whie back that you could take a block from an 5.7 olds diesel convert it back to gas and bore it out something like .125" or more. which is what he would have done for his '69 olds drag car......if it didn't already have a bigblock in it.
I remember reading in car craft, popular hot rodding, or hot rod magazine in the early to mid 90s about a guy that had a early 70s cutlass that used the diesel block. I probably still have the issue somewhere.
That would be the olds engine which was a gas engine converted to diesel.

10-4. and with the beefed block they used for that pure abortion of a 5.7 diesel you can bore the heck out of it apparently when converting back to gas.

I know back in the early 90's or so their was some buzz about using the Olds block,but I havent heard anything about that in forever,let alone seen one.
