    I'm runnin on pump gas now!

    Follow up with us after you try this out. I'll be interested to hear how it worked out.By the way, I have been assuming its an automatic?

    I'm runnin on pump gas now!

    You might have a little trouble with it with 3.23s in it. watch it VERY closely after the 2-3 shift at WOT, or at part throttle, heavy load. More gear is better, from an octane tolerance standpoint.

    Signs you have pushed it too far . Fly **** on the plugs, exhaust lash closing up.

    I'm runnin on pump gas now!

    Cold air will make a big difference in octane requirements, & I havent used the gas in your area, but I am betting this will be fine without the octane booster, assuming a decent rear gear. You may have trouble if you are running a 3.55, but if you have 4.10s or better, it should be fine. Try it...

    I'm runnin on pump gas now!

    My thinking too, try it without the octane booster. Depending on the rest of the car setup (cam timing, gearing, underhood/cold air, blocked heat risers, piston/head clearance) you are probably fine. As I tried to point out to another member on here, more octane=slower burn rate.

    I'm runnin on pump gas now!

    In BC we have Chevron 94, which is excellent. I have run 12.7/1 on it with a big cam (278/286 @ .050) tight quench, cold air/intake.

    M1 Single Plane Question

    Sounds like we have the makings of a friendly track test here. Mopers setup 18 initial 30 total, and the shooters it came with. Georges set-up 14 initial 35 total and ..040 shooters You game 69chrgr? lets try them out at the track, correct for weather, let the best man win?

    M1 Single Plane Question

    Your total is probably about right, Again, just a stab in the dark, I would try the initial around 14 degrees. Might even be right around there now, depending on how the distributor was set up out of the box.

    M1 Single Plane Question

    ABSOLUTELY. Yes, now that you tell me that, you NEED bigger shooters. I suspect you could probably stand a little more initial, would probably help throttle response, but I think the shooters are gonna be about 90%, more initial will get you the last 10%. Do you have a timing tape/degreed...

    M1 Single Plane Question

    How much initial timing are you running? 60' sounds pretty soft. Is it spinning a bit, or is the car weak out of the hole?

    M1 Single Plane Question

    As far as manifold mods, I havent worked on an M1, but most intakes respond well to a nice fat radius where the roof of the runners enter the plenum, and they usually need a little help in that area as they come out of the box. Nice fat radius on the leading edge of the runner dividers too...

    M1 Single Plane Question

    This sounds like a very well matched combo. Is the converter a 10"? What is the 60' time? What is the present et & mph? Is it hooked and leaving soft, or is it spinning the tires? Personally, if it was my car, I would work with the 950, as I think it could possibly pay a small performance...

    M1 Single Plane Question

    Heres the traditional method for setting shooter size. Snap the throttle wide open from a flat idle with no load. Keep going up in shooter till theres instant throttle response, then test drive the car. The right size is usually a size or two bigger than the one that works with no load. Might be...

    M1 Single Plane Question

    Yea, but what size are the shooters themselves? Have you played with the shooter size? I may be stating the obvious here, but if you increase the size of the pump, but use the same size of shooter, you are increasing the duration of pump shot, not the initial amount. Not sure if I am explaining...

    M1 Single Plane Question

    If its really rubbing you the wrong way, pick up some good 2-part epoxy putty, make sure its REALLY clean(cant emphasize CLEAN enough here), put your spacer on, and fill the gaps between the spacer & the top of the manifold, then go in with a die grinder and smooth out the transition. This used...

    Power Valve Bad?

    This is much more than an idle mixture issue. Once you fix whatever is causing the severe over-rich mixture(I am thinking float level here) THEN go back and play with the idle screws.

    Power Valve Bad?

    This is what I was thinking too. Also, if the back float is high fuel can slop out of the bowl vent when you hit the brakes, stalling the engine.That was what grabbed my attention.
