Hey its worth it when we were runnin points on are 318 valiant the timing would fluctuate and run like crap we had to change the points a few time till i upgraded it its nice , just go to a yard get a electronic dist a control box and cut the plug with enough wires to spice into it just get the diagram from big block dart .com its way cheaper oh while your at it get a newer style alternator and voltage reg from the same car its nicer too.harrytoes said
