1958-1962 261 Chevrolet truck engines had high-pressure engines with full-flow oil filters (metal canister style).
A 1957 261 would be a high-pressure (45 psi warmed up at idle would be real nice) engine that would use a by-pass oil filter system (metal canister style).
A 1957 Chevrolet Truck Shop Manual would have many of the engine specifications.
An engine with clutch assembly would be no more than 620 lbs.
A good engine would have 130 psi or better compression.
