Need 318 Gurus

I appreciate all the responses, there's a ton of knowledge here.

The engine and A833 is going into a 1975 Plymouth Trailduster.

My Trailduster Search Is Over

So, I don't have any attachment to which engine goes in it. Like I said previously, I want to install the orange motor because I believe it's ready to run and I feel more comfortable with the info I have on it.

I'm gonna sell the blue engine complete, as is. I'll get the proper pulleys, brackets, and radiator for the orange motor and be done with it.

I'd like to find some 6 rib pulleys, if they are out there.

Thanks again for all the help.
