67 Survivor - Tires And Oil Question

Just purchased an unmolested, completely original 67' Mustang Coupe with 289 - C code. The original spare in trunk is the Firestone pin stripe white - wide oval tire - belted bias ply. The car currently has radial tires. Do I replace current tires with original Firestone Wide Oval Whites - belted bias ? or a repro radial tire ? As the car is a superb example of a survivor and could easily join a preservation class event, I want to do the "right" thing.
Many will tell me the car will ride & handle better with radials, but the lure of the original Firestone WO belted bias tire (ala Coker or Universal) is tempting. Help please ?

Last question: Car has 83K well maintained miles on orig. C code motor. What oil should I be using ?

Thanks for any assist one might offer. Bigmac

regarding tires, that is ultimately up to you, since i dont go in for the total original look, i buy the tires i want. personally i would go for tires that look the part, but are modern radial construction if i were going to drive the car in anything other than just parades and to car shows.

as for oil, any good high mileage oil will do nicely.
