Hey Bob, Welcome to the bolt. Nice to see another Edmontonian!! Just curious, which shop sells cores? I think Iron Cheif sells cores or complete engines or something I recall...I don't knnow if I would buy from them though. Phone Scotts Super Trucks in Penhold, I was thier a few weeks ago and he has many engines. You could also look for a late 50's early 60's with a 235...I bought a 60 shortbox with a wrecked frame. It has a 235, fourspeed. Runs pretty good and I got it fairly cheap to. Eventually I am going to put it in my 53. Good luck!
