Recently purchased a 65 F-85 4 door with a V6 motor.

Does anyone know any details about that motor such as:

typical issues/ weaknesses or strengths
HP/ torque rating

Wasted

From a book I have it says that the 225 have 155hp and 225lbs or torque.It has a compression ratio of 9.00:1. Unfortunately thats all the book says about it.

This is an early version of the Buick V6 that was produced from 1961 through just this past year. For a while in the late 1960s and early 1970s, Buick sold the motor to AMC, where it was used in Jeeps, but GM bought the rights back after the first oil crisis in 1973. The even fire crank was introduced in 1975 to smooth out the engine's rough firing pulses. Later evolutions include the turbo Buick used in the Grand National and the supercharged 3800 motor used in FWD full size GM cars.

Not much in a four year old thread about a Buick V6...

Now if you have a specific question, start a new thread and we'll respond. Not to be a hard-@$$, but your question is pretty open-ended and likely won't get a useful response.
