360 got dishes
85 318s got the closed chamber swirlport fast burn combustion chambers(hart shaped) and a taller pist hight for a 9.0 to 1 comp ratio
that and a low friction roller cam gave it a nice boost over a older LA low comp 318.
the 88 360 headed cop engine I had was a flat tappet can but roller block,so it got a roller cam swap back in 07'
just pulled it after 300,000 miles and stuck the roller cam in another low milage 318 with #302 heads
between the 2 head set ups and valve size,the 360 were the best for HP/rpm and ran well on the street.
the small valves higher comp ratio has more throttle responce,more low end torque, but less top end HP and breathing.
torque is kinda peaky and higher up in rpm with less breathing up top
but i like the lunati voodoo roller cam 60710
258/264
207/213
.485/.485
great street cam for daily driveing a 318
