"Something in the Orange"
Without much research, I bought the first 340 I found. 1971 block with "Erskin .273 .480 racing cam, 030 KB slugs, 2.02 1.88 J heads mild ported new ss valves, Stock Cast '69 340 4bbl intake ported to match the heads". It was over the Cascades in Ellensburg.
That month I also flipped my pickup trying to avoid a couple that stopped to take pictures of elk. I beat the dent out of the quarter panel and replaced the rear window and went after that motor.
The intake and my new 650 was about all that was salvaged from the 360. I did the motor swap in a shop that used to be used to repair logging locomotives.
I discovered that the 340 was missing an oil gallery plug in the back by dropping the dipstick down from the oil pressure orifice up top straight down past where the rear main cap would be. I got a lot of flack from Whiteheads cuz they had to order a whole box of plugs to get me one! I also broke one of the bolt holes for the oil pump on that rear cap and had a local fabricator add a stud in there instead. I had to get an oil pan for my application and added a windage tray while I was at it. I got the thing running pretty good by the end of June.
