I'm thinking of pulling the fire breathing Pontiac 400 out of my '57 GMC for a smaller(more economical) engine. I just had a good '47 216 given to me-would that be enough motor for this truck? I just plan to use it for hauling trash and running errands,so highway use won't be an issue. I fear the 3.08 gearing will be too high for this engine to carry,but I can change from the tall 16" wheels to 15" wheels and 235/75-15 tires and soften up the overall ratio a little. I think,while I have it all apart I'll install the car 4 speed I have in the garage. Any comments/ideas from the worthy advisors?
