    Actually long tubes are for better low end and midrange performance and shorter tubes are better at higher RPMs as a rule. You have it backwards.

    Long tubes make power in the upper RPM's.

    Shorties make power low and Mid.

    Another good read.

    Second, JBA proved in both tests that its shorty headers produce more torque, while giving up very little horsepower, over long-tube headers, which have traditionally been believed to provide more power. And since torque is what gets you rolling faster, whether you’re going from stoplight to stoplight, duking it out at the X-mas tree, or towing, JBA has convincingly shown that for overall performance and easy fitment, a set of tuned shorty headers is hard to beat.

    Guess again, those are replacements for stock manifolds and are not being compared against regular long tube headers and they are too short to add any really tuning anyway other than balancing cylinder pressures. You ALWAYS use long tube small diameter for best low end and mid range performance and big tube ones that are bit shorter for hi RPM performance. This is headers 101 for 50's and 60's and this has not changed with time.

    I did. Do I need to find you guys another link on basic header theory like I did on how they use sound shockwaves to scavange exhaust from ports too?

    No man. I'm gonna get shorties for emissions reasons as well as performance reasons, which is why I haven't asked about long tubes.

    So, JBA, Gibson, Holley and others are wrong? I see.

    BTW, since when where shortie headers availible in the 50's and 60's?

    there are two newer dodges around here running those, one only has ONE STACK i MIGHT could see if it was a diesel, but they look stupid, i would just use them as side pipes instead of stacks.

    Well I would like more torque so I could spin the tires easier but I would like a little passing power.

    Ok what about some numbers?Ok so far we have this

    Shortys give you more torque and some more horsepower
    Long tubes give you more horsepower over the shortys but no more torque.

    As far as 50s and 60s tech goes, Yes those motors need long tubes because people ran cams lifts way over .475 and .500 because they didn't need vacum for power brakes and had soild lifters.Those cams don't even start making good power to 2,500-3,000 RPMs but they would run to 6,000 RPM or more as long as the bottom end could take it.Anything with a good healthy cam needs long tube headers.

    I have to tell you guys, snoman is correct on the header information. The ONLY "shorty" headers that can beat the longtubes for midrange torque are Tri-Y's; and even those will usually lose a few ft-lbs to the longtubes at low rpm's.
    On the Sporttruck article testing JBA shorties, the only difference that is statistically significant shows in one case the shorties lost 10 hp to the longtubes. All the other "differences" should be looked at as a wash. I'm not really surprised at their "conclusion" based on 1 and 2 ft-lbs variations! Remember, JBA is one of their advertisers; they have to give them some kind of credence

    The stacks did look good back in the day on the old Dodge Lil Red Express trucks.

    seems the only way to get a a true comparrison is to run all three types on the same vehicle.

    i went with shorties for ease of installation, cost, brand name, and materials used. and i am extremely pleased with what i got with them.

    so buy what you want. use what ever research you desire. they are all biased to sell their product. all of them are.
