Unhappy Difference between long headers and short

What is the difference between long headers and short headers. Also saw something called hugger headers. With the short headers, I will be needing a curved pipe extending to the exhaust, right? What would be ideal for a 69 camaro 350. Also, what is the key difference when it comes to 4-2-1 and 4-1. Thanks guys

Re: Difference between long headers and short

The main difference in short and long tube headers is the power and torque they make. Shorty headers are good for low end, long tubes are good for top end power.
Honestly I would go for longtubes headers. There are tons of headers out there for that car that are money friendly and work.

Dynatechs are real cost friendly and get the job done.

Re: Difference between long headers and short

It would probably sound sarcastic to say that the long tubed ones are longer than the short ones. I actually thought the long tube headers made the more torque. Doesn't scavenging come into play too?

Re: Difference between long headers and short

The long tubes ,make more torque up top, the shorties make more torque down low.

Ex. Longtubes. will make more Torque at say 5000 RPM and more HP
Shorties will make more torque then the longtubes at 2500 RPM and Less HP

is it better to have

more Torque at say 5000 RPM and more HP

or

more torque at 2500 RPM and Less HP

Re: Difference between long headers and short

Torque is what gets the car moving. But all in all, I have always used Long tube headers unless either 1. gorund clearance was an issue, or money the other issue.

I myself go with longtubes everytime I can. They make good numbers and work well.

After you decide on what style header you want, you have to choose the header that wil make the most power as they are all constructed and bent differently for power applications.

Re: Difference between long headers and short

We ran both on our circle track Camaro and couldn't tell a difference.Car Craft I think did a dyno comparison a few years ago and it was only 5 or 10 hp between the two.The shorties do give alot more ground clearance.But won't work with stock clutch linkage.

Re: Difference between long headers and short

I wont have a clutch linkage because if have an automatic trans, but I do have powersteering, which i know may come in the way.

Also, when buying for example short hugger headers, since the ground clearance will be much greater, do i have to buy additional pipes for the exhaust to curve and go up more.

I plan on buying a 2.5 inch flowmaster system, do they usually give more pipe than necessary or will i be need buy more and do additional modifications ( i know i will be doing some work with the exhaust, but in regards to adding more pipe thats not provide in the kit, basic question is, do they give more pipe than i need?)

You will need to have a shop bend you some short pieces to go from the header to the exhaust system.

Re: Difference between long headers and short

I think that you will find that the short, block hugger headers are really made for street Roadsters b/c they tend to dump right where ramshorns do so won't fit our cars!

Re: Difference between long headers and short

what headers are recommended, and are price friendly, im spending a lot on paint, engine, interior, and trying to the best i can! im looking in the range of maybe $50-150.00. I think im am going to go with the long tube headers, and 4-2-1 application

Re: Difference between long headers and short

Would these flowmaster pipes/exhaust fit this application of headers?

Re: Difference between long headers and short

Somewhere there's an article that tell's all about how primary pipe length teeter-tooter's around an rpm point for hp and primary pipe diameter teeter-tooter's around torque production and the same rpm. (OR something like this??)...

Designing headers is a real juggling act, and then throw in BOTH collector dia. and length, it get's complicated in a NYM!!

For a given engine combination, you have to find the right primary tube length and dia and then make sure all 4 pipes on each side are darn near the same length, then match these to the correct dia. and length collector! ALL for a given rpm!!

So this rpm become's the focal/design rpm "point" and you design to it and let everything else kinda rock on each side of it the best you can!

This is deep sh*t and I hope I haven't confused you.
