Frank - I really think it would be a neat conversion.
However, if you do this, do your homework.
The Buick engine weighs about 135 pounds more than the Chevrolet.
Have no clue as to the weight of the Flxible transmissions you mentioned, but probably more, maybe much more than the Chevrolet.
So figure an extra 225 pounds on the front end, plus moving the moment of the weight forward.
The Chevrolet pickup is from the factory about 62/38 front to rear weight distribution.
Adding 225 pounds is going to take it above 65/35 percent.
I do not have sufficient engineering background in chassis design to know at what percent the vehicle becomes unstable in its steering.
Front shocks and front springs would probably need an upgrade, as would the cooling system (320 CID versus 235 CID).
And maybe larger brakes? Differential?
If you do it, please post pictures. I think most of us would love to see them.
Good luck with the project.
Jon.
