I have one question

If i put on Hedman Performance steel headers on my 73 comet gt what sort of horsepower gain will i get?

With a 4 barrel Holley carburetor , and the dual exhaust with Hedman headers on. What total Horsepower will i be getting?

Also, a quick question. Does anyone know of a great cold air intake that can go on a Holley 4 barrel? That fits in the engine compartment of a 73 comet.

you should be close to 200hp. the factory heads and cam really dont make more power than that. spector makes universal cold air kits for carbs that you can use.

If i put in a Spectre cold air intake on it, then what sort of horsepower do you think ill have here?

Could anyone answer that one?Anybody?

Probably not much, that's why no one has given you an answer. There are other small modifications that will get you more power, for less money.

I can't say I have seen much talk about cold air intakes around here. Just plain ole air filters. Chrome air cleaners make horse power too

it depends on what you currently have for a filter. i would expect 5hp at most.

for best seat of the pants gain, changing the rear gears to something like 3.25s-3.55s will give a good performance gain. also a looser stall converter in the transmission will help it jump off the line.

what do you use the car for?
the more info the better we can guide you.

Don't bother going to the track, till you put some decent money into the car.
