Updating 6 cylinder 1954 chevrolet
One interesting fact about the 235 inline 6 is that it was the engine that was used in the first Corvettes that were produced in 1953 and ran up through 1955.
Their base engine, also produced only in Canada, was the 261 not the V-8 as in the US.
Hydraulic lifters will only function in a block that has the oiling passage drilled through the lifter bores (which hole will be plugged and visible on the rear of the block, just above the cam plug).'58-'62 engines must use a lifter with chamfered sides to prevent shutting off rocker arm oil! Also eliminate any engine with the little tell-tale triangular plate and curved oil line in the middle of the driver's side. On the block above the end of the starter will be an initial (A-L), followed by either (2) or (3) numbers. Easy..of the curve will need to be taken out of the accelerator rod.
NO oil line from rear cam bearing to block center will be found in the pushrod chamber of these engines and, in addition to the I. criteria (above), will have a triangular side mount pattern.5. This tells you it has the dreaded dipper rods and splash oiling. The initial represents the month: the numbers are the day and year the block was cast. Squeeze it in a vise until it makes its travel without rubbing the floor pan (as installed in the bellcrank, without return spring).
This provided basic power, great dependability, and better gas mileage.
Basically, this larger engine was a 235 with the same crankshaft but GM engineers made various modifications to give it extra strength and horsepower.
This allows for the use of the larger, late model fan, which provides better cooling.
