Intake swap
I have a '65 F250 with 390, and I am in the middle, literally, of swapping the intake manifold and carb. The dizzy will lift up a little bit from the manifold, then stops. I have tried rotating the dizzy to no effect, as well as rotating the engine. I recently replaced the dizzy with a stock rebuild, in which the swap went smoothly. From previous posts, I assume that the dizzy is binding at the oil pump? More force, or remove the oil pan? Thanks.

Thanks for responding puttster. This is my first time doing an intake swap. Is it better to pull the water pump, or can I install the intake manifold along with the short bypass hose? It's looking as though I should have purchased alot more gaskets. In addition, the throttle cable bracket from the previous 2 bbl manifold looks to be too short. I am installing a Performer RPM intake with a Performer 600 cfm carb, along with a bracket for the trans. kickdown that will place the throttle cable about 2 inches beyond and above the old bracket. Maybe I'm stuck with fabricating a new bracket. Thanks.

Better to pull the waterpump too, that bypass hose can be a bitch that complicates setting the intake back on without disturbing the gaskets. If it's an iron intake, use an engine hoist and save your back.

I can't help you withj the 4 bbl conversion linkage but the performer will sit at maybe 1 1/2" higher so you may have problems with the front of the stock air cleaner clearing the hood. Autozone sells a 14 x 3" open air Spectra that fits, though.
Regarding the bypass hose I have AC and PS so I would give a try without the one-day add-on work on the water pump and brackets. I'd ream out one end of the hose and grease it up withj PB blaster and see if you and someone can fit it in there and still set the intake properly on the front and rear seals. Seems quite possible especially if you are using a hoist. If not, find a thinner/bendable hose and after you get that on, split a bigger hose lengthwise and put that one on over the thin one for support. As a final "no remove" plan, you could plug both nipples and drill a hole in the thremostat and that can be your overfow. These three plans are successively crummier. If you only have the alternator on a belt I agree, just take off the WP.
Speaking of theremostats, the Performer takes the small one so you may have to buy a new water outlet to match it. Good luck, and report back!

FEs switched to the small thermostats (same as a 289) in 1967 or 1968.
