Wow lots of info probably wont get into pistons and cams though as I won't be towing often great info on HEI and plugs I didn't know they made a comercial plug I probably won't change the ignition this week as I won't gain any power but still might do in the near future how about the 4 barrel carb the guys that tryed this did it help in power anyway I still have a lot to do to the trailer but am going to look for the comercial plugs
Thanks for the info
Dave
