Thanks red,

Why your 0-60 times with the drags are slowest (2.038, 2.300)?

Just how good is the MSD retard advance unit in your opinion?

(please forgiveme guys if I'm out of topic want to know about the spark plugs too)

I just took a set of +4's out of my L98. After less than 10k miles, they're shot. Dirty, chunks of crud in the electrodes, etc. Parts store said that was normal wear and tear. I'm going with AC Delco RapidFires next.

;shrug the only good 60 foot time is when the car goes streight
which is not to often
the 1994 corvette is not known for great starts and some times i forget to put the car into drive o-drive makes the cars 60 ft times
realy slow converter will not lock up in od.
dont put an accell fuel presure regulator on your car I tried 2
and the second almost blew my engine.
airamotive is the one i have now but not sure want to take a chance of vapor lock again.
the chevy dlr put an aftermarket reg on the car and it sits at 43.5 psi so that is what it should be runnning nos.
the pin retard unit i tried first was a pain to get to
i like the dial on the center console that way i just reach back and turn the bottle and the retard is their too.
the knob is known to have problems but so far i havent had any.
also 160 stat.
