The '70 GMC my sister has was originally 307 powered and dad's current '68 GMC project was a 305 V6, he used the big car mounts on both engines and made his own frame mounts in order to position the engines where he wanted them, The '70 has RA manifolds and the '68 will have plain logs. Here are the pics I was referring to in the assembly manual. You can clearly tell its a Pontiac engine by the valve covers, exhaust area, and the bolt going fro the timing cover to the intake.
