L.A 360..Magnum ?

Unless someone is trying to run a certain class or build a stock appearing street car or show car I don’t know why anyone would want to spend money on old cast iron junk.
I know if it were me I'd go to the next bore size on the early 360 and use 4" kit, promax heads, victor340 with 1/2 spacer, .engle .560 solid 108lsa, mancini billet time set ,10.2 comp and be done. That will do what he wants and then some.
