Help on rebuilding a 73 340

hi, the 1.88 int valve is sufficient to make good power, esp if you install sst valves. the port velocity is very good with those. the 73 should have the 587 heads. those flow very good!!!! the stock int and T.Q are very good items. in stock elim, those 340's can run low 11 sec to high 10 sec. the low comp motors are runners. the comp 262 extreme energy cam works great in the 340 for street use.
