. . . And did'nt the 235's in 60's trucks have hydraulic lifters too? . . .
No 216 engines had hydraulic lifters.
No 235 engines up through 1949 had hydraulic lifters.
No 235 and 261 truck engines had hydraulic lifters.
1950-1955 Powerglide car engines had hydraulic lifters (except in a Corvette).
All 1956 and later 235 car engine had hydraulic lifters.
261 Canadian Pontiac 261 engines had hydraulic lifters.
All 1958 and later 235 truck blocks (and, I think 261 truck blocks) were drilled to accommodate hydraulic lifters.
The above information notwithstanding, I am not sure if 235s used in trucks with a factory Powerglide transmission had hydraulic lifters (I would guess that they did).
My 235 has hydraulic lifters. Came out of a '55 First Series and was a Canadian-built motor.
