D4B DC mods like the LD340 DC mods?
@go-fish Here’s a pic of my pistons when I was assembling my 273. I used 302 heads that in the final windup had 58 cc’s and 1.88 intake valves. A little massaging, but nothing crazy. I ended up with 9.8 compression wit these pistons. More than enough for what I wanted. Mild hyd. roller cam. I ended up with 260ish HP and 280 lbs. of tq.
