273 302 318 340 build

So another option.
I found a 1974 318.No heads or intake. Bore is .030 over, pistons have 4 valve reliefs. Seller sounds honest. It was in his Duster(340 car)
He didn't do the "work" on the engine but was told to only run it on 93 octane and was told it was approx 9.5 to one compression.
He is going to get measurements how deep in the hole and the bore.
It also has a "purple cam" 429/444

Opinions on this 318 vs the one I already bought (1985 date).
1985 318 I can keep/refresh and drop in my 84 Prospector.
Thanks for the input
