OK, here's more.
I checked my owners manual (this and the maintenance manual are reprints
available from most vendors and more than worth the price), all the 100
series models (101 & 102) all have a gross vehicle weight of 4,800 pounds.
Series 150 are 5,800 pounds, therefore 102 must be a long bed 1/2 ton.
Other things:
rear axle raio 4.11
248 displacement 248.5 cu.in.
bore 3 23/32"
stroke 3 13/16"
compression 7.5:1
S.A.E. horsepower 33.19
Max recommended RPM 3400
for those of us with the stock 228
displacement 228 cu.in.
bore 3 9/16"
stroke 3 13/16"
compression 8:1
horsepower 30.45
Max RPM 3400
now I have a quesion. The two motors are different, with the larger being
20.5 cu. in. bigger.
The horsepower is barely different, why is that.
the 228 has a higher compression, is that because of the smaller bore?
I've heard a higher compression is better, why?
