Ok I'm looking for some slant 6 engines. and I found one that I can get for free from a 68 dodge truck now I'm wondering if this is the same as the ones in the cars?

Hey and welcome.

Changes were incorporated 68 and onwards as far as the crank is concerned at the rear on all slants.

Truck slants as far as I understand, has shot peened cranks, double steel cam roller gear and chain setup, and some even had thicker cylinder walls - here in RSA anyways - our blocks were cast locally.

More heavy duty

Just say I own a few Mopars

If it's original it might have a shot peened crank... (so far I've taken apart a few truck motors from the 60's and one 70's industrial engine and no shot peened crank was installed...)

The one thing I do know is truck mills sometimes had lower compression ratios than their car counterparts (bigger combustion chambers)...

If just looking for a block to work over, stick to 1968-1976 for a forged crank and the bigger crank pocket.

Happy Hunting...

Interesting. Never seen any evidence of same. There were LC pistons primarily for export markets with low-quality gasoline, but year upon year there was only one cylinder head p/n and none of the truck engine specs in the Weertman material refer to extra-large combustion chambers. What year truck engines have you seen this on, and did you take note of head p/ns?
