I got a call from the shop yesterday, "we need to talk to you." I thought OMG!!! How much is this going to cost??? Turned out not much and not too big a deal. Actually it was good because I learned something new. The original engine in my Barracuda was a 273. Swapping in a 318 "shouldn't" be a problem. Well, I found out today that it might be, depending on how new or old you 318 is. Early 318's shared engine mount dimensions with the 273. I don't know what year that changed, but the passenger side motor mount pad on my 1986 318 is the exact opposite of the original 273. They can fix (modify) the engine mount, but I wish I'd taken the time to find an early 318 block so this wouldn't have been an issue. There was also some issues with the trans kit but I need to collect my (not so good towards Keisler) thoughts before putting them down.
