Looks great, nice install.
I plan on installing a set of these too, soon.
Did you have any words of wisdom or specific tools that you would recommend to us who have yet to tackle this install?
Glenn, ratcheting wrenches are a life saver. A second person will cut the time in half. A good set of gloves, my hands were pretty tore up by the end of the day. I also did it on saturday then drove it for the week and put it back on the lift the next saturday to go in and just check everythings tightness.
iam looking into headers also, not sure which ones to go with. i get lost when people speak in "mechanic" when they say long tubes are good/bad and shorties are good/bad. i just want lamemans terms, which headers are good for daily driving and towing once or twice a month.
JBAs are a very good street-oriented choice as they bolt in place of the factory Iron exhaust manifolds and they increase power across the board.
That being said, the Long Tube style headers offer even more horsepower and torque gains than the Shortys, but require you to replace the factory mid-pipes as well.
Also, with headers a big selling point is Primary Tube Diameter. The larger the tubes the more ultimate HP and TQ the header will be able to comfortably support before being a potential bottleneck to the system.
So the JBAs have 1 5/8" Primaries and there are 2 different models of long tubes offered in both 1 3/4" and 1 7/8". As with many bolt on go fast goodies all the parts have the potential to make serious power, but most do so by trading low end torque for extra power at the peak of the RPM band. Also with headers, i have seen it written in header related tech articles its better to go slightly small on primary tube size than slightly too big.
The 1 5/8s JBA shorty headers dont make as much peak power as, say, a 1 7/8s long tube header. But the JBAs will still increase your low end torque and provide you with good throttle response over the factory iron manifolds.
If the application is a mostly stock daily driver that sees some towing, my personal suggestion would be the JBAs.
If you prefer the long tube style of header more I would suggest the 1 3/4" primaries over the 1 7/8 unless you were looking to use a stroker motor later, forced induction, large cam etc.... http://www.popularhotrodding.com/tech/1111phr_how_to_size_headers/index.html
here is an excellent article by David Vizzard on header sizing and why.
Hope this helps you
She definitely has more pull now. I don't know how much is directly from the headers cause I did headers fastman TB and the vararam in the same weekend. Theres more of a rumble at idle and slow accel fast accel I don't hear a difference but I have a exhaust cutout so its just always loud. lol. I am hoping to go to the test and tune in albuquerque on the 31st to get a real test on it. Oh and the headers are JBA I got them off of autoanything.com
