Is the fuel pump leaking fuel into the oil? A lot of times when the diaphram fails they start spraying fuel into the crankcase. You should be able to smell it in the oil.
Depending on how bad you may be able to have it posished out, worst case turned.
If you find a 390 engine, I would be interested in the 390 rods. Going to stroke my 360. Have a crank coming allready.

It's hard to heat the oil up to a high enough temp to catch it on fire. If your were burning oil, I do not see it putting it self out, if the oil is that hot. If it was that high your temp gage would have been pegged. I don't see spinning a bearing heating it up the oil high enough. Are you running rich and washing the oil off the cylinders into the crankcase? or Maybe the crankcase ventilation system is not recirculating the vapors into the base of the carb .....
Are you sure it was in the crankcase burning the oil?

How many years did that pump lay on a shelf somewhere before you bought it?
Did the inside of the box have a musty smell?
A brand new/rebuilt pump doesn't mean it's any good = especially if it was Made in China..

How's the oil pressure? A spun bearing most times will drop the pressure due to the extra clearence between the crank and the bearing shell...... A heavy knock like a thump most likely is a main, the lighter rap a rod.
on another note blue68f100 what will be the advantage of strokeing a 360 over the 390?

whitenight2,
im up here in modesto at the local pnp i noticed a few fords with 360/390's in them. might be worth the while to pull one of these. or do what i did, i went to modesto re-new and they machined a 390 for me, just bored .030over re-did the crank new flat top piston tanked the block with new freeze plugs and cam bearings. and new push rods only cost me less than $1,000.00. all i had to do was put all the pieces together.
and since ur only in clovis, feel free to join the northern cal chapter. a few of us are going to the show in pleasanton this sat and sunday 11/10-11/11 feel free to join us. u can pm me if you want to know more.
