i have a 73 camaro with a 350 V8 and my plan is to eventually make it a pretty hot running car. i just replaced the stock 2brl carb with an Edelbroch 600cfm 4brl. i was thinking that maybe some headers would be a good next move. there is a lot that i want to do, but i am on a budget. what do you think?

I think headers would be a good idea for the next step in adding power. If you were to put a higher performance cam in , they would usually call for a 4 barrel and headers.

heaters is a good but you should put a better cam in it then it should run better

I also replaced the 2brl carb with a Edelbrock 600 cfm 4brl carb on my 69 camaro 350ci. Then I put headers on it with replacing the original single exhaust with a double exhaust system and a new turbo muffler. The car would be run next friday. I'll tell you more.

How much HP do headers usually add to an engine? I'm thinking of doing something to my IROC LG4.

Well, Running Headers on a 3rd generation Camaro is going to be trickier than it seems. From experience, unless you get REALLY serious about re-routing the entire exhaust, monkeying with it usually just results in serious flow issues. Unfortunately, as I'm sure you are aware, replacing the stock logs with headers will also necessitate purchasing a few additional exhaust pipes to compensate for the change from the manifolds. Most of the time, you will end up with a poorer flow than the original manifolds allowed. Depending on the year, you may or may not be able to get away with dumping the converters/
and mufflers to gain room. I know that on an '85 - '87 you'll be in rough shape no matter what. Hope this helps.

Headers on a 3rd generation are only OK at best, as the system to be legal must retain the catalytic converter. Edelbrock's setup works good, and fits excellent. It has the tubes for the AIR welded in place, and comes with everything you need. The only place that is a tight fit is if you have a engine cooler mounted under the oil filter. Expect to spend 8-10 hours installing them.

If it was my car, I'd take out the exhaust manifolds, borrow my neighbor's die grinder, and grind away. I did this to my '69 because headers are such a headache sometimes, and even worse in your car. After your done porting the manifolds, upgrade to a good, mandrel-bent, 2.5" dual exhaust. You'll be happier in the long run.

So, yesterday my car runs with a new edelbrock 600 cfm 4brl carb, edelbrock intake, flow tech headers, a new flow tech dual exhaust system with two mufflers. The sound is great, and the power is excellent. The only problem with headers is that the car is a little bit lower with it so you must be carefully when you drive.

MY RESPONSE WOULD BE TO SET A GOAL ON HOW MUCH HORSEPOWER YOU ARE AIMING FOR AND LOOK FROM THERE .BUT A GENERAL RULE OF THUMB IS IF SOMETHING IS IMPROVED ON THE INDUCTION SIDE OF THE ENGINE THEN THERE SHOULD BE AN IMPROVEMENT IN THE EXHUAST SIDE TO EQUATE IN A BALANCE... BUT THEN AGAIN IT ALSO DEPENDS ON OTHER FACTORS TOO ...

I just finished rebuilding a '78 8-350 tuck motor to put into my 87 IROC Z. The problem is i had a 305 and now have a 350. I need a set of headers that will bolt into my exsisting setup. If u have suggestions write back. My other problem is i am running one straight pipe through a hollowed out cat and splitting it in the rear of the car. It is a little to loud and i dont think i have enough back pressuer. If u have any suggestions on keeping a nice deep semi-loud tone tell me how it is don
