Best Years for the 318 LA?

I'm glad someone finally mentioned the 9.2:1 difference in a 318 thread.

I'll add that the late LA rollers are likely to be a true 9.2:1 or very close vs the often "lower than spec" earlier builds where the 71-83-ish "8.8" motors are commonly tested as 8.5:1-ish.

I'd imagine this also holds true for the 67-69 9.2 motors but not sure I've read about one actually measured.

Also not sure how much of the comp increase is due to the head or the piston 67-69 vs 84-91.

Either way, that also means if you need pistons for a 71-83 engine, a factory replacement for 67-69 or 84-91 years should have ataller installed height, giving you more squeeze.

I also can't remember if 1970 is an oddball one year only ratio like the 383 HP that went from 10:1 in 69 to 9.5 in 70 and then lower for 71.
