Yea I got it from the junkyard the wiring harness that is and yes the 318 came from a 2500 and idk if it was light duty it's in great shape

 

the 4500 never came behind a 318 iirc, only the 360 and bigger

edit: take a pic of the rear axle if you can. that way we can tell if its a ld or hd

 

Oh crap I may have the 360 how can I tell

 

Thats what I was thinking too...

well the sticker on the core support woulda been great... haha the side of the block, behind the starter, will say 318 or 360

 

Oh crap I may have the 360 how can I tell

 

No go there's just a casting number

 

Get VIN and get build sheet.

Ok fellas I found out I'm te proud owner of a 360 lol sorry about the double posts it's my phone. I have been working on changing up the wiring harness for like three hours and still counting I an having to convert the v-6 wiring harness to a v-8 it's working tho just a pain. Idk how to post pics on here or I would. But I have another question on this truck there is no y pipe the two pipes off of the manifold go straight into a two in one out cat so my question is what are the advantages of stripping the cat out since I already have it off it wouldn't be hard thanks for the help guys

 

Ok time to go in the house for a while I'm about to start throwing things I have wiring lol I think im going to go ahead and get the damn motor and tranny mounted before I screw with the wiring anymore
