i pulled an engine at the junk yard today so i can rob it of the manifold, fuel rails and engine covers. how do i tell if it is a 4.8 or 5.3? i pulled it and it still had all of the accessories on it but when i pulled them off the 5.3 was painted over with a yellow paint pen or something. does that notate that it is a 5.3? if it matters, it has 862 heads on it.

 

Did you pull it out of a truck? If so go get the vin number, but if now, then you'll have to pull a spark plug and try to see the top of a piston

 

it was a suburban, the whole cab was gone but the rear hatch and most of the front clip was there but thats all. i wasnt even going to but anything but i saw this motor sitting there and knew it would only take me about 15 minutes to pull so i grabbed it

 

what should i look for on the top of a piston?

 

a dish on the top of the piston is a 5.3, flat is a 4.8. since it came out of a suburban, i would guess its a 5.3.

 

how much did u get it for?

 

suburbans don't come w/4.8's.

 

im gonna say 5.3 also, but as stated, the pistons will tell you for sure

 

ummm, i got it at awesome auto salvage so you know......

 

i have never heard of a suburban with a 4.8 but i just checked and it is a 5.3
