I have installed the 484 and it looks great! Pics will come soon! The engine bay has been degreased and painted gloss black, so it looks like a new car! The 484 has been broken in, and after much tuning and a rebuilt trans, I was able to drive the car once again. It had been off the road for almost two years for this project that slowly came together! The engine still needs some tuning, but has tons more power already that the little 425 did! I have dual exhaust coming off iron manifolds from a 76' 500 that flow better than the 79' 425 manifold. The gas flows through dual 2.25 inch Dynomax mufflers, and has a nice big block V-8 sound!
