should be the 318 swirl port closed chamber heads and little ports 1.78/1.50 vales
around 9.0 to 1 CR,roller cam(short nose/no fuel pump)
904 would be lock up and low gear set(may have the silnoid VB for the lock up/wire in the back corner on tranz case)
it will resond well to a LD4B intake and 600 eddy carb,headers with the stock roller cam
the lunati roller cam 60710 is a good one for a street engine,use comp 901-16 springs and the stock roller lifters,push rods,rockers
258/264
207/213
.485/.485
it will have the LA style oiling to the rockers thru the heads
and it may have hollow PR oiling thru the lifters also,I have had a couple like this so far
the early roller cam engines did not have the oil thru roller lifters
just something for yout to check and look at while you cleaning it up and painting it
my last one is a 88 cop engine 318 with 360 heads,I swaped in the lunati roller cam and hardware from a 1990 318 tbi engine(4-v 318 has 360 heads and flat tappet cam with roller block)
