putting 68 396 into 71 c10
Will a 396 automatic out of a 68 3/4 ton truck work in my 71 c10? Could I just use the mounting hardware out of the 68? Didn't know if there were frame differences with the donor truck being a 3/4 ton and a 68.
Thanks!

It will bolt up for the most part. Make sure you grab the frame towers for the engine mounts, those are big block specific.

So if I have the donor truck, I should have everything I need? Will this motor run on regular or will it need premium?

Is the engine stock, if it is regular will be ok depending on how far the timing is advanced.
I have '73 454 and it runs ok on regular gasoline.

I'm pretty sure it's stock. Still has qjet and cast iron manifolds.

I would put a can of SeaFoam in the gas tank with the next fill-up. I usually do that when an engine has not been ran for a while. Most auto parts stores carry it.
