Those appear to be very reasonable spring pressures for a hydraulic roller!!!!, no need for solids in my opinion. Your rollers should live a long life with those spring pressures. I suggest pulling your distributor to look at your camshaft, you will see the #1 intake lobe, you will have to use a mechanics mirror. If it looks good I would not touch the engine. The only problem the light springs may have causes is hammering on the backside of the cam. 347 based on 302, i have never heard of a lubrication concern with those engines. Mustangs go well over 200K miles.

Problem is the roller lifters. According to some, engines with such should not be idled at all, due to oil starvation. They rely on oil- splash from the crank only. Unless they are of the modern type with oil channels to the pins/ rollers. |
