what does the L6 mean an in 216 L6 and 235 L6? when did the 235 get side mounts and when did the bellhousing pattern change where it bolts to the motor?
I don't know what the L means, but I think I did know at one time. The 235 got side mounts in the early 50s and again in the late 50s in a different place. I think 53 and 58 The bellhousing pattern was always the same on the 216 and 235. The 230 etc introduced around 1963 use the V8 bolt pattern
Thanks Mr, Chevrolet! I think I needed to know that! I have been reading and using L6 not I6. Great observation!
223 powered '55 Fords even had an "I6" emblem on the front fenders. Chevrolet passenger cars got side mounts in '52, and used that configuration through '54. '55-'57 235s moved the mounts up toward the front of the block (but still on the side of it), and the '58 235s saw the mounts move back to the '52-'54 location, but with a different bolt pattern.
Some folks used to use the L as a reference to the flathead design (but not regarding Chevy sixes). .
Lets throw the word "straight" into the mix also ... straight six (eight, etc) which are "inline". Which includes all ... slant 6, I6 (OHV), and L6 (flattie).
I fully understand the useages listed here......but....I have seen, repeatedly, the "L" used with 6 for engine type designation. Always wondered why it was used by whomever. Maybe RUSTY 1 has something there with 'linear'..... Ever notice how in for sale ads ANY 6 cylinder engine is advertised as a V6? Lots of incorrect useage out there. Ray
