Re: 1972 gmc steel tilt cab with a 637 v8
Just LOVE that engine! It idles so smooth. Single exhaust yes?
Thanks for posting the videos.
A few requests;
Can you post a photo of the emblem and does it say 637 V-8?
Would post a close-up photo of the black engine family sticker on the passenger side valve cover?
This is such a Kool Truck. Thanks again
