>>>True, but everything I've read and heard says the pushbutton cars had

11.0:1 compression, while later '71's had the compression lowered to closer

to 10.0:1, using the same heads.  Wouldn't that lead you to suspect that mild

pop-ups had been replaced by flat-tops?  How else would you make the extra

point of compression go away?



Ted?  Jack?  Anyone here ever taken apart a 69-70-early '71 Cleveland?
