I just bought a 1969 El Camino that came with a #'s matching engine. The numbers on the pad say "TOI16HB" and then the vin# is also stamped there. The casting # on the back is "3932388". The heads are "3947041" with date codes "L30 8" and "L2 8". What are those date codes? Would these be original heads for this engine? I searched around and can only find the "HB" listed that says it's an L48 300HP 350. My El Camino is just a normal model / Non SS. Would this engine come in a plain jane Elky? I've read that this engine came in an SS 350 camaro. Any info you can give me would be appreciated. This is my first El Camino. I've had 3 Camaros before. Thanks.
T0I16HB is the engine ID. T means the engine was built at Tonawanda, NY, 0I16 is January 16, and HB is the suffix code for a 350/300 L48 w/TH350 transmission. The partial VIN shows what year/plant/sequence number the engine was to be installed in.
In my reference material, the 3932388 block is kind of an unknown. Most 69s received a block cast with 3932386 and the 388 blocks found were dated from Sept to Dec of 68.
Nothing unique about the heads, typical 350/300 with 1.94 intakes and 1.50 exhausts. Dates are December (L) 2 and 28 of 1968 so they're correct for a 69 car after December of 1968 and would be right for the early January dated engine.
Plain Jane? Me, I cringe when I hear that term. Makes anything less than a fully loaded car sound mundane. There were two series of the El Camino; 300 Deluxe (134/13480) and Malibu (135/13680). The Malibu series had nicer trim appointments but the engine could have been ordered in either trim level. The play of 'plain Jane' against an SS Chevelle/El Camino in 1969 is really unfair. The 396 SS option in 1969 was just that, an option just like a/c, a radio, etc. On the El Camino side the option was only available on the Malibu series and included the engine, trim, etc.
