Agree 100% Well worth it! The headers are a pain for sure(I use CPPA,very similar to the TTIs out there now.) My little 470" will put a big smile on your face for sure. A little bit of chassis work(sway bars,frame connectors) and they handle/drive just fine.
With all the difficulties of installing a BB in an A body, the distributor is in the front. All worth it to me. Tired of laying across the fender or carb trying to tweak or work the distributor. I love it up front.
