340 or 360?
In keeping with the 340 vs 360 theme, early (1971-1974 cast) 360 block. Heavy main webs a lot of people have put four bolt caps on successfully and many have sonic tested that were good for .060 over 340 bores and beyond. Plus the five of them I’ve had my grubby mitts upon didn’t have the stupid counterbore in the lifters a 340 does. That makes running roller lifters less of a hassle, too. So, yeah, positive deck 340 piston 370 plus inch motor that could stand all the power available from a good set of aftermarket heads. Sign Me Up!
