I've found that I'm driving my '49 GMC 3/4 to work quite often and I get up on to the freeway to get to work. Amazing how many people I [censored] off by slowing their day down to 50. Oh well, the kids all wave! I'm a little worried what RPM the original 228 is turning. Has anyone installed a tach in their truck and if so can you outline the steps and type of tach you would recommend. The truck has been converted to 12 volt.
Thanks
Murph
