By no means am I an athority on it, but I believe a Lyc. 0360 strait valve
is typicaly a 180, with the angle valve being a 200 or 205 hp.
and the 0320 Lyc. strait valve being 150 hp. with the angle valve
being a 170 hp. But with all the mixing, and matching of this part and that one
on theese motors who knows for sure? Like I said there are a bunch of folks
on this sight far more qualifide to answer the question than I.
carb or fuel inj. also comes into play on HP ratings.
