I run the F&B 6 pac on my 1970 Cuda 440 http://www.fbthrottlebodies.com/
And no I didn't pay that much when I bought mine.

I run it with FAST EFI controller. My system has been running 5 years with no issues.

As others have stated, there is a lot more you need to do than just bolting on the system.

My Monster are real!
