Just out of curiousity, is it posible to have the stock rods and crankshaft from an engine strengthend to withstand more abuse if there is no aftermarket rods/cranks?

 

boil them in used motor oil maybe? i know that you can harden tools that way.

 

hahaha, I assume any kind of good brand motor oil will do? boil at 400 degrees for how long?

 

You can have the crank polished, treated, have the rods shotpeened.. Peeing the stuff takes all the strees out of it.. However unless you plan on making 700+ hp with it, the crank is fine.. Cranks have been in 1000hp setups with no problems..

 

Thanks, I'ts for the 4.3 giving it to a friend after the swap just wanted to know for his dumba$$ sake if they can be strenghtend. He's known for running WAY to much boost on his crap.

 

he will lift a head before he damages the crank

 

Atomic has a point, how often do you see a broken crank?

 

you can also do cryogenic treating for the parts

 

plus 1 for cryo. i have had a lot of parts cryo treated...rotors, pads, tranny internals.

i bent a crank once.... .040 s curve in the bitch. hahaha

 

Years ago we used to bake the rods. Put them in the oven at 400 deg and bake them for 6-8 hrs. If you look is some old Peterson Hot Rod Chevy build books they had pics of them going into a kitchen oven.
