In the early 60's, GMC used both a 305 and 350 CI 90 deg. V6 that shared a
block with the 305 and 350 V6 diesel counterparts. (Heads, crank, rods,
pistons, cam and intake were different, as well as having an injection pump
instead of distributor...).  This was a very torquey engine... My dad had
the 305 in his 63 GMC pickup... you could dump the clutch at idle in 4th
gear and it wouldn't kill the motor... it would chirp the tires and start
moving!
Later,
Dave
