Silv-O-Lite Pistons Good or Bad?

Well, there are some specialty pieces involved. You'll need that adapter that adapts the later model crank to the early converter. CharlieS has those. And of course, you;ll have to find a V8 cable shifted transmission. But the swap is pretty straight forward. I did my 65 Valiant years ago. I installed a later transmission though. Dougs also has headers too. They are long tube and will probably produce more torque. I had them on my 65. They installed easily and fit very well.
