Ignition popping
I recently put a 350 with a comps cam, power band 1500-5500, 4.10 rear end, converted the camaro to carb. My question is I have a summit ignition coil, thats suposed to put out 60,000 volts, and its for a points igntition which is what I have. Now everytime I get on it down the track it starts making this poping sound usually around anywhere from 5-6 grand. Causing me serious time in 1/4 mile, I pull 1.9 60 ft times but can only get 14.6s for my time. Im wondering if my points are the cause for this poping, if they cant handle the high rpms. Thanks for any help

You can shelve that point ignition any day now... This is the year 2001 of the new mellenium. We have beauti new invention.
It's called the transistor..... Just kiddin'
Assuming your plugs wires and cap are in good shape. Try replacing the points with accel medium tension points. Replace the condenser too. Your "60,000v coil" may be
creating too much voltage for your cap to distribute (cross fire). Try adding a ballast resistor {approx 2 OHMS}(accel, chrysler) to the + connection to reduce current to the coil.
This will increase the life of your points and reduce cross fire. (exessive voltage)
Check the distributor shaft for side to side wobble. Some Accel distributors seem to wear quickly here. Make sure the timing isn't over advanced (32 to 36 total @ high rpm.)
Do not run "hot" stock heat range plugs at the drags They will overheat and glaze.
If you normally use AC-R45TS, go to
AC-R42T(S) or champion RV8C. Hope this helps.
