anybody have this one..?
they look like an easy upgrade , but, do they really do anything.?...

didnt think so either....thanx
I put a set of full length Hooker headers on my '78. It made a world of a difference. I'd consider full length duals w/ an X pipe, high flow cats, and other goodies that help the engine exhale.
Not sure what is CARB approved and what is not- I'm sure that will be a consideration for you because of your state.
X pipes are better, better flow because of savaging effect. An h pipe merely equalizes the pressure between banks. I'm running stock manifolds/cats, x-pipe with muffler eliminators. Not as loud as you would think. Cats do a lot of muffling. X pipe also cuts resonace and interior noise big time. Way better than the stock resonator does. Much deeper sound too...I love it. Pain the butt to install however.
Shorties dont get you much, the stock LT1 manifold flow very well. Long tubes on the other hand, yeah buddy!!!!

Jane AnnOkay guys... this is probably going to sound dumb, but I don't have much in the way of technical knowledge and I find your conversation interesting.
As I understand it, headers, x-pipe, hi-flow cats, etc. are beneficial because they move the exhaust gases out faster, thus reducing back pressure. Increasing air induction on the front end and increasing exhaust flow at the rear equals increased power ie horsepower, correct? Is it increased power or increased torque? See, I told you it would sound dumb.
So, other than the obvious, :L what's the difference in short headers versus long tube headers, performance-wise, that is?
Thanks for your patience.
Anything you do to cause more air flow to an otherwise stock motor will move the power band higher up the rpm scale. This will result in a decrease in lower end torque.
To increase exhaust flow you want the exhaust to be as smooth as possible. The less conections in the system the better. Anything that could cause turbulence will slow down the flow. That is why long tube headers are better. Shortys will not be much different than stock manifolds.
it wont work in mississippi....Okay guys... this is probably going to sound dumb, but I don't have much in the way of technical knowledge and I find your conversation interesting.

short tube headers are just stock manifolds made from tubeing..not enough gain to notice..
long tube will scavenge the gas and cause a lot more out = more in....dig.?:cool

To sum it up, any internal combustion engine is basically an air pump. The more air you can get in the more power you can make. AKA. what we in the know like to call "Volumetric Efficiency." Turbos and Superchargers increase Vol. Eff. dramatically that is why your boys Honda 4 with 30psi of boost can make 500hp. Anything beyond 100% Vol. Eff. is only possible with boost.
To explain this further, when your intake valve opens and the piston is going down it creates a vacumn in the cylinder which air rushes into at 14.7psi (1 atmoshpehere), the amount of air is dependent on the flow of the heads, RPM, Camshaft-Lift, Duration, Overlap,etc...if you are getting lots of air in you need to get it out. Hence, a exhaust system that scavenges the gases out will help Horsepower and torque.
How much HP you gain or lose and the same with torque is dependent on how you build your engine. Any moron can build a big HP motor, but it is the guy that can get big HP number while maintianing low end and middle range torque aka Drivability that is the REAL engine builder.
Without further making this more complex, I'll explain the REAL DEAL and my PERSONAL OPINION on making HP.
Whatever intake, heads, cam, exhaust, etc...you choose it all HAS TO WORK together. You can take a bone stock LT1 and stick a big nasty cc306 cam in it, but you wont reach the real potential of that cam. WHY, not enough head, intake, or exhaust to accommodate the Air Flow potential of that camshaft.
Whatever you do beyond a free flowing exhaust or cold air intake...GET A TUNE!!! Your engine cannot reach FULL POTENTIAL without a TUNE!!!
I can go on but I don't want to lose anybody. Not that I'm insulting you, but I'm digressing into pretty technical stuff, here. Hopefully, this is clear and we are just scratching the surface. For the record I'm no expert in H.O. engine building but I am a auto. tech. by profession and understand how engines operate.
