I'm assuming that the engine you describe is somewhat high compression and as such both the sparkplugs and the plug wires need to be in better than average condition or you may experience some misfiring Also, if you have an exhaust gas analyzer available, check to see if your engine is running a little lean at lower speed. BTW, at 4000 RPM it's also possible that you just can't TELL that the engine is misfiring any more. My contribution: On racing big blocks with misfires, I try to reduce the plug gaps, say to .035 or less and then later open them up if the problem is corrected. Don't use projected nose spark plugs in a high compession engine. Use the standard nose plug, I like NGK these days. I hate .060 gaps in a racing engine. I assume you have a quality coil and a good MSD ignition box. Racing engines like a lot of initial advance or fixed advance with a locked out distributor. Check from distributor rotor alignment when at firing position. The MSD website has a tech page to show how. Another thought is that holley carbs can be very rich at idle and part power and cause a rich misfire. Correcting this is a whole other subject.
have the alternator and the battery checked
never
The battery does not have sufficient voltage to start the car when it's cold. Have the battery checked out. If it still goes click click after running the car for a while, have the alternator checked also. A bad battery will not hold a charge and a bad alternator will not recharge the battery, (That is the reason to have the battery checked first). Make sure the connections at the battery are clean and tight.
Have the battery checked.
Is it charging, if not have you checked wiring to alternator.
Get the alternator checked before your battery goes dead.
Sounds like either loose or corroded battery terminal or bad fuseable like
Have your alternator checked. It could also be a bad cell in the battery.
you should go to a car shop and get your battery checked and ask how long should u charge your battery.. or if you should get a new battery
Bad starter solenoid? Loose or corroded battery terminals? Weak battery? Bad neutral switch?
You need to charge your battery or get a jump. Replace the battery or have it checked because it is dead.
Probably loose drivebelt. or alternator belt of it is seperate.
