1975-76; 250 ENGINE PICTURES would help

[old cool]

Hello,
I recently had a forum member decode my block pad numbers (stamped near front of engine) and found I have a 75-76 block. Possilbly head too but I have not removed valve cover to see #'s. It in a non-integrated 250 (separate manifolds bolted to head just the 60's engines.
My truck is a 1966 gmc. What I am attempting to do is compare the appearance of an "original" non-intergrated 1975-76 with the engine in my '66 . I'm quite certain they will look same since i dont have the integrated version; but, I thought a couple of photos from both sides and front (balancer) would be interesting and confirm my guess.
Any help would be appreciated. Love the forum. Thanks for reading thread.
