right now i have shorties on my car, it baackfires a few minutes after running, im wondering if this is normal due to no back pressure, or is my timing off? the hedders are not hooked up to anything,.

Open shorties? Could be either one. Check timing, check firing order, hook up exhaust...

do you have anything hooked to the headers?

Check timing and make sure no plug wirs are crossed.

thanx guys, im wonderin if it could be my firing order, i had a shop do some work and they may have crossed the wires, i need a diagram of the proper order that i should place the wires on my cap, it would help, thanx again.

No problem.

thankyou dan

Let us know what happened when your done.

well i checked the wires and they are all on correctly. Im thinking that my timing is off coz im runnin too rich, when i had my exhaust on i was getting fumes comin out the pipes. I dunno if thats it but at least i found out that my wiring is good.

check your spark plugs. They might be fouled. If you are running rich like you said, then there is a chance that one of the plugs is fouled.

but i just installed new plugs recently

That's okay, a car running rich can waste no time fouling up plugs.

Put go ahead and fix the timing as that's alittle easier than doing plugs, right??

Backfire through the carb, or backfire out the exhaust? If its through the carb, you timing is probably retarded. Also, make sure non of the ends of the wires have been torn loose.

backfire through the headers.
