You may want to start looking for another spare,the weight(pizza ovens) and miles on that style truck seem to eat motors.
The company in Ct doing what you are with similar trucks keeps a spare motor in shop.
My son and I are planning on
doing that. Though after going through all the little things that popped up I may just get his 46 rebuilt and converted to bearing inserts.
Back to an 11" clutch.
I got a NOS 1946 GMC oil pressure gauge. However the gauge numbers are printed on the glass so even though my son has 35 PSI at idle his gauge reads 15. I can buy a repro GMC instrument panel glass with the correct oil pressure numbers.
The problem is when swapping out the Chevrolet IP glass with a GMC glass the speedometer will not be correct. Win one lose one.
Though I think my son's 54 235 rebuilt engine should last along time. He is driving it and not an employee. He rather go up a hill slower then shift up and work the engine harder.
Also most of his work is on east end forks. The north fork runs are 10 miles or less one way. Montauk can be 30 by ferry of 60 road one way. He does some work in western Suffolk and Nassau maybe 60 - 70 miles one way. Compared to Connecticut and upstate New York the hills are not as long.
We went with the 54 for 17 HP more. Though my son has only driven it to two jobs since the rebuild was done he is not sure if he is feeling the extra HP from the 54 engine. Jeffrey
