As far as how I like it, so far so good, but I don't have much driving time with it yet (winter). But, the idle is good. Smoother than I thought it would be, but enough lumpiness to know it's there (you can hear it in the youtube link in my signature). Good vacuum for brakes. Seems happy with casual driving at lower RPM. Very strong mid range. That's about all I can say so far.

Edit: I will say that if Cliff recommended it, I'd give that an awful lot of weight.

John,

I think what is holding back the idle is the X-pipe. I have changed all my cars to H-pipe. each car's idle was held back in terms of deep sound and the lope of the idle. In each case, it changed the sound to the way I want the car to sound like a muscle car.

Here are a before and after video of my 1970 GTO running a 461 with the off the shelf XR 288. It is the same cam you have except the LSA is 110.

Before:

Exhaust is Magna Flow with X-Pipe

After:

Exhaust is now Flow Master American Thunder Series with Texas TA mufflers and H-pipe.

Big difference in sound.
