You're in the same boat as me, im in Ontario and I'm getting the 390hp 360. I've only been to one shop and they told me that the engines all come from the states. So I'm asuming that any performance shop can get them but it might be cheaper to order straight from mopar to your house.
Well I phoned up Cutting Edge in Kelowna and they said right around the same price to do everything to a 360 to get 320 hp out of it. The same as one of those crate engines, but in canadian dollars....cheaper and without shipping. So I think I may just go see Daryl
But you have to remember after the motor there's trans rebuild headers new exhaust new rad new drive shaft 8 3/4 rear end. Maybe 8 or 10 grand. Two years down the road lol.
