The "Indestructible" Slant 6

Right. Go back and look at the small end of the rod. I know it's a press fit there, but look how black it is. That's HEAT that caused that. Something was up there.

well this went down hill quick... and he says its like the biggest carb... hmm... probably because its starting to get enough fuel!

correct piston to cylinder wall clearance? im sure not

correct ring end gap for boost? im sure not
:wack:

when you put the small block chevy in i'll make you pop that motor trying to keep up with the slant!

Yes heat would cause piston siezure.

Probably running marginal A/F ratios & that particular cylinder was the leanest.

Piston crown gets hot, ring gap never opened up from stock for the added heat of boost, ring/piston siezes & the cank yanks the wrist pin out of the skirt.

Once the rod was loose, all kinds of bad $hit happened.

One thing for sure, the bottom of the piston did not come off AFTER the rod left the crank. Impossible for that to happen W/O some severe downward forces from the rod on a piston that was held stationary.

The OP appears to not have enough mechanical apptitude to anylyse what happened let alone set-up a homegrown forced induction system.
