71MonteCarloMD Posted August 22, 2020 Share Posted August 22, 2020 Been searching for classic truck to enjoy with my son, bought this 1972 GMC C15 5 Quote Link to comment Share on other sites More sharing options...

MCfan Posted August 22, 2020 Share Posted August 22, 2020 Cool - even has running lights in the windshield visor! I'm guessing a C15 is a two-wheel drive 3/4 ton but my pickup interest, awareness and nomenclature has never matched the autos. Great that you have something out of the ordinary to enjoy with your son - he's a luck kid! Quote Link to comment Share on other sites More sharing options...
71MonteCarloMD Posted August 23, 2020 Author Share Posted August 23, 2020 Dennis, thanks and from decoding the VIN, it’s built in Baltimore plant and a 1/2 ton as I’m not sure if the windshield visor is original to the truck. By the way, can anyone tell me how I can find engine code to decode if it has 307 or 350? Quote Link to comment Share on other sites More sharing options...
Dtret Posted August 24, 2020 Share Posted August 24, 2020 (edited) Back of block behind the heads where the trans bolts up Been a while but I believe drivers side just look down behind the head with a flashlight if engine is clean it’s really easy to see Based on it being a truck I don’t think it’s a 307 Edited August 24, 2020 by Dtret Quote Link to comment Share on other sites More sharing options...
71MonteCarloMD Posted August 24, 2020 Author Share Posted August 24, 2020 Thanks, not sure if can easily access to behind of headers with motor in truck. From LMC trucks as it seems that 307 is with 2 bbl and 350 with 4 bbl, will explore more... Quote Link to comment Share on other sites More sharing options...
Dtret Posted August 24, 2020 Share Posted August 24, 2020 Behind head top of block where top driver side trans bolt Look down beside master cylinder behind valve cover with flashlight. It should be very easy to see. If the engine is relatively clean. I didn’t realize gm put a 307 in the 1/2 ton truck.
