i've seen stock build 340 six pacs pull 390 hp no problem on the dyno . they were underrated like most dodge engines

I find that hard to believe
I will buy 320 hp for a 68-71 340 but don’t buy an additional 70 hp with tri power, the 440 six pack only added 15 hp over 4 barrel . Even an early 383 rated at 335 hp only gained 8 hp with
2 four barrels
