ok, so yesterday was a grand day indeed, the B and I went out for a day of driving, first time ever, other than around the block. everything was wonderful with the exception of the interstate, the car idles smooth and accelerates like nobodys business, but at 70 mph on teh freeway at 4000 rpm, i can feel the engine fluctuating, timing is good, no pinging, carbs appear to be fine, only thing that comes to mind is vacuum advance, but if thayts the only time its erratic, im just gonna leave it alone and stay below 60. but al in all, a great day!
