Hi Newbie here.

I'm looking at buying a fair condition 1965 F-350 tray truck which has a 300 CI originally fitted. It has dual wheels and I'm wondering which 4 spd box and diff would in it originally? The owner doesn't know.

Also, I'd like to keep the 300 engine and would like to source the "heavy duty" inlet and exhaust manifolds which were in the later model 300 CI dump trucks which had enormous flow to fit to my engine. I wonder how to identify them and a place to purchase them? Also I'd like to upgrade the front and rear brakes...any easy to fit reconmendations?
