Last time I was at FFR they had an FIA using the kelsey tires. Polyglass are DOT, soft and reasonable in price.
I run BB on rear and Powercushion up front. Seems to be a working combo...
Remember that 289 cars dont use the tire sizes of the 427, they are too big.
In the day not even the 427 used tires as big as today's.
My suggestion is a moderate front size, in terms of MM 215 or 225 and rear 255. 
In bias front 6-6.7 and rear 7-8
CSX3021 fronts were the Powercushion type, were 6.70x15
