Not Ranked
If you are planning on using a genuine 427 SO, Tremec TKO, and want IRS, I'd spend the extra money and either get a superformance, CSX4000 roller, or kirkham instead of the FFR.
You could always buy a used unique or something, already with an IRS, with a 390 or 428, for not much money, and switch out the engine to the 427 SO.

The crowd was jumping up and down as he stunned the Chevrolet drivers by easily passing the entire field to finish second behind MacDonald's other team Cobra. The Corvette people were completely demoralized."
