I've seen that Bill, pretty cool. I guess pretty much all the way through that period say mid 60s-early 70s, Chrysler was doing all the engine dynoing and just relaying to the drag teams what to use? I look at the way the Hemis were in terms of build in the eary-mid 70s, especially after seeing many of Stuart and Fred's pics and the difference blows my mind. Like night and day. Seems like there must have been a pretty momentous increase in HP just in that short time span. BTW, we seem to be getting an inch deep and a mile wide on the post view. Wonder what happened? Posts have gone real wide for some reason or is it just my comp??
