Question about 1995 Chevrolet Camaro
I am currently working on a 68 camaro to which I slapped a 454 w/ an 8-71 blower. Had it dyno-ed, herd it run perfectly. Now that I've actually
slapped it in the car it is real hard to get it started.The first time I tried starting it I found out the dyno guy had left the distributor rotor cap loose.Started that time.Now it doesn't start again. Now here is the mind-blower. The other day I was cheking it for spark and as soon as I tested the #1 plug I saw a pretty healthy spark when I ground it to the block and (surprise) the car started. Now I cant repeat the same scenario.Now I can barely get a blink ,or any at all.
?What exactly did it indicate when it started by grounding the plug???
I've added grounding cables,the distributor is getting spark,added perfomance plugs,replaced wires (resistance check),etc,etc
First, I am strongly against dyno testing on anything but a protype motor, unless you intend to tear it down after testing and check everything over. You should not be running more than 8 to 1 compression, especially on gasoline (too unstable... Id rather work with nitromethane) carbureted or injected?. If your distributor (by the way, what type?) takes its power from the same source as the starter, it's possible that cranking is pulling too much voatage from the ignition (why I used to use a vertex magneto on my racemobiles). (what kind of starter) If your battery is in the trunk,and it should be, use "00" welding cables to run power to starter. attach ground either to one of the starter bolts, or close to the starter on a bellhousing bolt.Use the largest battery you can find.(in cca's) In my opinion, you should be using a good set of silicone/steel ign wires (unless it's a doorslammer and you like listening to the radio)Re-set the static timing to about 8degrees to begin with, and it should start.Unless there is an ign problem (internal) You really didn't post enough to work with but try what I said, it's a good place to start!
Good luck, keep me posted! Whats next a 1471???
