New, fully assembled, BluePrint 408 with front pulleys and 727 package

I recommend the Lokar cables. They usually save the aggravation of modifying and fighting stock linkage setups.
I agree. There EZ to set up and work excellent. All of my rides (except my E-body Cuda) came as a 2bbl. from the factory.

I looked into it, and the cost increase to eek another 20 HP out of the standard configuration didn't make sense at the horsepower per dollar level. I called TFS a few times to see if they wanted to work with us, and never got a call back. So with that $$$ rocker setup, and paying Almost retail, I don't think many would spring for it.
The rockers are a bit pricey....
Your short block would be the easiest way to get there. Then the purchaser can add your or there own cam to suite.
