My 1954 Truck Operators Manual says: Valve clearance (hot engine) - all engines (??)
intake 0.010"
exhaust 0.020"
My 1954 Chevrolet Truck Shop Manual says: Adjust valve clearances as follows (hot engine):
For 235 Thriftmaster 235 engine
intake: 0.006
exhaust: 0.016
For 1 1/2 & 2 ton trucks(not clear if this is for the 235 Loadmaster or 261 Jobmaster engine)
intake: 0.006
exhaust: 0.020
I use the settings in the shop manual.
The car settings might be different (and the 235 Blue Flame 115 might have different settings than the Blue Flame 125).

That could be the source of confusication. It hurts the valve seats more to have them too tight than too loose.

???So, which is it???
There is enough good in the worst of us and enough bad in the best of us that it does not behoove any of us to criticize the rest of us.

By all means,put a brick on the gas pedal so the engine warms up- on a 235 about 5000 RPM for 20 minutes should do it, v-8's I figure about 7500 RPM and 30 minutes or until the last rod flies past your head (don't forget to count!, and main bearings don't count).

Also from what I have heard from some of the fellas that used to race these engines 5000 rpm wouldn't hurt them anyway. (obviously with a lot of preparation) We have a sense of humor and enjoy a joke as well as the next guy, but you need to contribute something useful as well, this site has a purpose... | | |
