my junk runs fair for a daily driver

88-318
360 heads-1.88/1.60 in a 85 stepside with NV4500 5 speed

from the factory out of a 89 police car = nothing special but does have the better 85-up 9.0 CR pistons .020 in the hole.

I have a hughes whiplash roller cam for the 318 magnum. made for the stock low comp engines and street duty.

I run a holley street dom intake with a 6210/650 DP spredbore along with headers 2.5 duels, 3.55-29x9.5x15

is it a racer? no. does it do well in daily traffic? hell yea and gets 18 mpgs.

I cruz mine 100 miles a day x5 and at least 100 on weekends.

IMHO, the right cam will make or break it.

the #302 heads did just as good. just moved the torque peak on the rpm band by a few 100 rpm.

I can live and be happy with less with my junk. I am happy to drive a mopar everyday no matter how slow or fast it is.

from a hot rodders view I can see don't do it. but from a daily driver view and the fact the Ma Mopar did it there is no reason not to do it.

the papers I have show the stock 88 #302head 318 has 150 HP and the the 88 318 #308head 4-v police engine has 177 HP. AND with a lower comp ratio rating.

not much but it is where it is needed in daily traffic.

results vary and depends on what you want to do with the 318.
