'67 GMC Truck Valve Covers
Hello Folks,
I was wondering if someone on this forum might be able to help guide me a bit further in one bit of old race car research. Yes, trust me, this comes back to GMC trucks, I think, so please bear with me. Several 1966 and later small block Chevy powered sports racers (Can-Am, USRRC) and Formula 5000 (Continental, Formula A), ran a stamped steel, no hole, and no "Chevrolet" script valve cover. My notes and some pictures of the valve covers in question can be seen on this link to another forum dedicated to old Trans-Am Camaros: http://www.camaros.org/forum/index.php?topic=8146.0 What led me to this forum, was reference to some very similar GMC valve covers in this thread (in particular, the posts by "1967C20"): http://67-72chevytrucks.com/vboard/s...d.php?t=348960 It would seem that these plain (no "Chevrolet" script because it's a GMC), no-hole small block valve covers look to be a good match, but I can't be sure. Would anyone on this list be able to comment on whether the 1967 GMC (or 1966 for that matter) small block equipped trucks came both without holes and wire retainment tabs? Additionally, would anyone know specific part numbers for these items? I have the ability to source and modify the applicable bits that could reproduce this look, but I'm really just interested in finding out from a historical perspective, what may have originally been used back in the day. All the best, and I welcome any additional feedback... if you're still reading and interested. -Chad |

Re: '67 GMC Truck Valve Covers
The plain covers with no holes are from a 327. 327's had the oil filler on the front of the intake and crank case ventalation on the rear of the engine.

Re: '67 GMC Truck Valve Covers
Bessie is sportin a pair as we speak... She's a 67 CHEVY C20 with a 327.....
Mine have no tabs, and are interchangeable from left to right, they do however have a slight canted angle to them so if you put them on upside down they will rub the rockers... ask me how I know. ![]()

Re: '67 GMC Truck Valve Covers
Thanks "Screamin_c10", I appreciate the feedback.
Indeed, I too remember first learning about the different cant of the opposing inboard and outboard sides of the valve cover. I look forward to anyone else perhaps having something along the lines of a GM part number. Thanks again. -Chad |

Re: '67 GMC Truck Valve Covers
The pre-PCV SBC truck valve covers will be the plain/no holes. I believe maybe the cars from the late-60s also. The earlier 327s had a V impression in the center and the 265/283s had the script
