FWIW..... All 318's are cast cranks (except for some of the early forged truck cranks) and all 318's are internally balanced. So no external balanced flexplate or TC for any 318.
Cool...I stand corrected on the 318's. I thought late 60's 318's had forged (same as 273's), and went cast in the early 70's along with the rest of the engines?
