a few questions in one...
are all 261's full pressure oilers? i just read an article in the tech section explaining how to turn a 261 into a FPO. which years were and were not. is the '57 i am considering an FPO, i really want to avoid a babbit pounder
can anyone tell me where to find engine specs for a '57 261. i am in the process of purchasing the engine and the gent who is selling is doing a compr and oil press test for me..i also need to know the weight of the full engine, no bell housing clutch or trans. this is for shipping purposes.
while i am at it, can anyone recommend a good freight company. so far AAA Cooper is the best priced, but the are a hand off shipper and turn the motor over to NEMF. not that i mind but non stop would be best.
thanks
big ed

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.

thanks. has anyone seen a 57 truck shop manual online for viewing?

A '57 261 would have a high-pressure oil lubrication system and a by-pass oil filtration system (with 3/8" oil lines, I think) | | | | | Joined: Nov 2007 Posts: 29 'Bolter | | 'Bolter Joined: Nov 2007 Posts: 29 | Is a 1954 261 has high-pressure engine with full-flow oil filters ? 39 7M | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 | No.
1954-1957 261 Chevrolet truck engines have high-pressure (or full-pressure) internal lubrication and a by-pass oil filtration system (unless someone converted the engine to a full-flow oil filtration system).
