I had a nephew that lived in Sandy UT & went through there to see him back in the 70's.

HA HA HA! Nice! The creeper still runs to this day. They do christmas rides up the canyons. And the only time they really shut her down is when the fire danger is too high!



So now- how do you know about the creeper while you live in FL?

X pipe it is! I installed an X pipe on my brothers 331 we built last summer easy enough. Now it's the Sanderson short tube truck headers, and some mufflers and I'll be ready to shred my tires.

   Charlie, not to any serious degree. Jets (secondaries) are impossible to find for Teapots,the primaries were not affected. I tried timing, but it made no noticeable difference. Most of my mixture issues have been just keeping enough fuel in the float bowls. When I have that solved I'll play with jets. For now, with the blower, I prefer rich enough to keep the pistons solids rather than liquid! 

  Glen, I think that the "finding room in the car" issue is probably what killed the 180's. They don't seem to work enough better to warrant the added weight and hassles. Except in Formula 1, and I could care less about those clowns.

Glen,

I ran the same thing for several years on my dirt track sportsman and was convinced they helped pull the car off the corners on the smaller tracks with tight corners.You're sure right about them being a pain to install.Maybe the best thing about them was the unique exhaust sound.Everyone could always tell where I was on the track because of the sound.My son always said it sounded like a pissed-off hornet.

Back in the early 80's we ran a set of true crossover headers on my scrub late model race car. They were a real pain in the ass to install. but they seemed to perform well. We didn't have access to a dyno back then, I bought them used from Neil Bonnet who swore they were good for twenty HP. I don't recall who made them.

That makes sense, Frank. I think you can look at it as if the pipe from the header to the X is a collector and if the gas can exit through 2 mufflers, then the portion after the X will be much like exiting the tailpipe to atmosphere. So with the X you get less resistance and pressure balancing whereas with an H you only balance pressures.

Did you tune the carburetor or timing at all when going from the full exhaust to headers?

    To add to what Ted said here, and this is only an opinion, I think the fact that each cylinder exhausts into two mufflers instead of one, helps lower the maximum pressure spikes. This effectively lowers the backpressure each cylinder sees. I've read the same articles in different Hot rod magazines, in all cases there was a noticeable difference in low end to midrange torque. Top end, not so much. I suspect the advantage is exagerated in my case because the motor makes comparitively less torque until the blower spools up. i need everything I can get at launch.

Due to the imbalance of the firing orders from bank to bank on a V8, a crossover pipe will enhance lowend torque.  The closer the pipe is placed to the engine, the better.  X pipes are the ultimate in crossover pipe technology as the distance between the two exhaust pipes or tailpipes becomes minimal.  The Mustang mags have tested this to death and although I don’t recall the numbers, the crossover pipes always helps where the system must be run with a full set of pipes.

 

And here’s why the crossover pipes work.  When examining the firing orders of any V8 with a 90° crankshaft, you’ll find where two cylinders on each bank fire consecutively and then miss a beat.  The crossover pipe helps to balance out the surge in exhaust pressure in a tailpipe that is a result of cylinders on the same bank firing back to back.  That pressure surge ends up in the other pipe and eventually into the other muffler.

 

Ford and Mercurys started using crossover pipes in the early Sixties on the dual exhaust equipped cars if that’s any consolation.  For the race cars, 180° headers are available for some applications where clearance permits them and this allows the firing order to alternate between paired collectors in a defined manner.

 

Here’s another thread with some similar information.
