Does anyone know why some of the phase I cars came with headers and some didn't? Some pics of cars show headers some without?

It was an option (not standard with the 380hp). The Bobby Labonte Blackbird #38 has them.



NASCAR Long Tube Headers - an $1,800 option. (hard to see in the photo)

I see. My berger has them . Do you know if all the berger cars had them or if it was a special option? Seems to me that the ones with headers would have had more HP than the ones with out? thanks for your info Jim.

Really Jim ? :confusion-shrug: I would think that the difference would be "night and day" because the car can certainly breathe better now ! ! ! ! ! :auto-layrubber:

I did some research most say with long tube headers and free flow cats with a good cat back anywhere from 25-40 hp.

Let the bench racing begin............. Sure it breaths better but.............



If I was at the track I'd expect to see a difference. It's hard to tell on the street without any timing devices unless I'd line up a non header 380hp next to a header 380 car & run them side by side. There really isn't a reference point on the street- the cars are @ redline in no time.



It's no different from the Phase II & IIX cars on the street. A 380 with headers is not going to run like a Phase II/435 & a IIX/475 will be quicker than a 435. Yes the IIX seems a little stronger but it's hard to tell how much without the watch running.



I know what my Phase IIX (auto) SS #45 runs....... 9 runs on the 2009 HRPT on street tires (4 @ Union Grove & 5 @ Bristol) - just unloaded the stuff from the car & ran it. Fast run was 12.4 & slowest was 12.51 (about a tenth difference in 9 runs) - pretty consistent for an old guy. No one beat me in 9 runs on the HRPT & I think I was in the top 3 or 4 fast times. Remember this was a 5k mile road trip & a couple of the quicker times were trailered race prepared cars. There were a lot of guys 'talking the talk' that couldn't 'walk the walk'. See the Bristol run against the '57 Pro-street Ford Wagon.



With that said I'd put Berger SS #45 up against any other GMMG at the track & we can find out. Run 'what-you-brung'.......Road trip/ street trim - no tuning - no trailer queens - no race prepared cars - just take the stuff out of the car & run it.



Union Grove run ....



Bristol staging.........





Check the bottom of this link to see the consistency.........http://www.daytonapacecars.com/id16.html



The next year I ran PE #37 (Phase IIX) - 6 speed @ Newton Iowa on the Power Tour & times were all over the place with a 6 speed. I can't shift as fast an a automatic.



Bench race all you want guys................ The only way to know is line them up under controlled & timed conditions.
