My original 340 Duster was a 3 speed manual '72. It came with a cast crank. Could the forged cranks have been restricted to 4-speed only and not all manual trans?
I don't think there's a definite answer to the question of where the last forged cranks went in production. I have read that they were used in four-speed cars till the supply was gone and cast cranks where the order of the day. What month of production was your 72 duster? It seems more reasonable that the Forged cranks had been used up and all cars were getting cast cranks by the time your car was assembled.
I don't recall. That car was totaled almost 50 years ago. IIRC I'm thinking it was a late '72 model.
Right. Plus, that car was a Mr. Norm's and had 12.5:1 TRW's in it when I got it. No telling if they changed out the crank at that point, but not likely, as they would have had to swap damper, timing cover and radiator at the same time.
Yep, it’s at the machinist. He measured the bores and said it will go .030. Also having it decked & rebalance the new rotating assembly.
