Early 360

There was an article in the mid(?)-'70's called "Hoover's Mover. Tom Hoover (Father of the Hemi.) Put together the original version of a "big bore" 360. Using much machined OEM low compression 340+.020" pistons, He put the budget combo into a notchback Barracuda that ran very well before the aftermarket had performance 360 pistons.

I gotta do some digging to find it and refresh my memory on more of the details.
a 360 with the 1972-3 340 +.020" piston was a way back in the day to get a 10.5 low budget piston. 360 +.060" = 370 - not exactly big bore.
