I have to ask, why would a Piston being installed as long as it has and under my own torture that I put on this Engine endure to 130 mph where I found all the internal problems and solved them over time. In the beginning the Rocker stud nut was cracked and I replaced them with 7/16" screw- in studs. While there, we installed the Johnson Hydraulic Lifters, a new oil pump and HD Chrome moly Push Rods, had a new timing Gear and dual chain.

The # 886 Cam was worn out, but who knew at that time. I had the Tri-power Carbs. completely rebuilt, by us OfCourse, using genuine Rochester parts that would have come in these Carbs. from the factory. We installed the 1/2" spacers under the Rochester's too. We had Air Induction as well and the Carbs. are up-jetted to a 428 ci Motor. So, this combo. at 70 mph, stomp on it the secondaries come in with the kickdown gear and I launch from 90mph to 120 mph throwing me back into the seat and moves slowly to 130 mph tops. Now you all tell me that I need to build the bottom end today, now?

I tell you this Engine is a monster and I still carry extra weight in the trunk due to the posi-traction W/ four-wheel Disc Brakes.

Mike, How fast you think the car is doesn't really pertain to the state the engine is in. Everyone's perception of a fast car is different. It may run well enough in your eye's, and if that's satisfying for you then so be it. Piston slap doesn't have a huge detrimental affective on engine performance other than poor ring control, which may or may not be showing itself at this time. What it does do though is make an annoying noise that changes with rpm, sometimes goes completely away as higher rpm is reached and/or warmer temps. You'll just have to decide if ya want to live with it or rebuild the engine with a fresh overbore.

There has been a bunch of good advice given. Unfortunately some have told you what you wanted to hear and going down that path so far has not fixed your issues. It costs money, but eventually you'll have to bite the bullet and fix this thing right.
