    speedway has a cheap set that is very good.........
     
  3. CAN they be run? YES
    WILL they make ANY power? NO
     
  4. In my opinion they do not sound very good with a low compression kinda stock motor, especially with baffles.

  6. Doesn't matter, on an unblown car, a collecter type header will ALWAYS make more power over a wider range. And since he said a little over stock it will sound like ass as well as look stupid :D

    Be sure to drill drain holes at the bottom of each pipe, or you'll get a freebie bath at start after every good rain. See the other thread for tennis balls / covers, also. Lots of dummies think they are ash trays. Gary

    I ran 2-1/8" zoomies on my 355" engine and they absolutely ROCKED - even with the pathetic 9-9.5:1 flat-top engine. Everybody thought it was a 12 or 13:1 engine.

    The "internet experts" also told me it would never run on injected alcohol at that low compression. It ran 8.70's at over 150 mph with a mild roller cam.

    Was I giving up power? Yes.

    Was the "cool factor" worth it? HELL YES!

    Make sure you have a decently lopey cam, though, even if it's a hydraulic flat tappet.

    Oh, yeah - I had multicolored "splash bombs" in the pipes when not running.

    And don't waste your time experimenting with pan-evac - it doesn't work. I capped mine off and ran the breathers to a Moon puke tank.

    They sound like crap with baffles. One of the guys we go to coffee with, just put them on his T-buckets. They are more annoying than anything else.

    Thought i would add my two cents im a sound engineer by trade and know a bit about sound deflection. the easiest way to figure out what you like with the exhaust tone is build a set and experiment. I run a set on my 327 10.5-1 with a huge cam they sound awesome but they due pop and i made the entire setup including baffles from scratch 4 hours per baffle in machine work...

    With a stock engine, think smaller tubes.
