If that 318 is 71 down and the 360 is 72 up, you won't bolt the crank pulley on. The bolt pattern changed in 72. The 71 and down has one offset bolt, 72 and up is symmetrical.
318 is a 69 and 360 that I'm Prob gonna use is an 85 but it has the pulley on the crank and I hope it lines up with the rest of the 318 stuff. I suppose time will tell lol.
