Tried to PM you, box is full, curious on price on a late 69 or 70 block, we met thru Dave at ProTrans, I sold you a 8" convertor back then, I live in Lancaster still.
Block and heads in ad is Very Very Early = June 67 casting.
I try to run the earliest castings I can find in our stock
and superstock 340s. The castings seem better with thicker
cyclinder walls in my experience...
