I found a guy here in town that says he has what he "thinks" are three 6.0 motors. Once again, "thinks" they are. He's had them for a couple of years and said they came out of trucks...blah,blah but can't confirm the size for me(and he's offering a decent price for everything he has) Is there a way on the outside of the motors to tell whether it's a 4.8,5.3, or a 6.0? I know for sure they're not LS1/6 motors because he DID know they were iron bottom motors vs. aluminum. Thanks for any help, Bill

 

no help or did I just ask an extremely stupid question without knowing it?

 

No, its not a stupid question, unfortunatly I dont know the answer ether...

 

well there is a 6.0 truck engine and the LS2 is a 6.0......

 

Best way to tell would be by the casting numbers... Get the casting numbers of all blocks and check them out at
Mortec.com

 

there are 2 iron 6.0 motors a ls4 and a ls9

 

Correct me if I'm wrong but arn't the truck variant of the LS1 motors all iron. They may be LS1 after all.

 

scratch that I've been drinking to much tonight. Jeez i need to stop (got confused with the Gen III motor, newb mistake there).

 

I think you meant LS2. The LS4 is a 5.3.

 

the iron LS 6.0 motors are LQ4 and LQ9. I knew that already and I have a 5.3 combo(still for sale) I was just asking a simple question is there an easy way to determine whether it's an iron 4.8, 5.3 or 6.0 without tearing it down and measuring parts etc. I saw a stamping on the back of one 6.0 crank that actually said "6.0" on it but if the flywheel/flexplate is still on it you'd never see it. The guy here in town is pretty sure he has a 6.0 but before I buy it I'd like to make sure exactly what it is. Thanks anyway. I'll try to find some casting numbers for the block I guess!!!

 

Ya thats what I meant
