    440 very rich at idle, lower vacuum

    Do you have a PCV, or is the port on the carb for it capped off? What happens when you adjust the idle mixture screws? Any effect? Are they all the way closed? If mixture screws have no effect, one cause could be a blown power valve. Is the choke adjusted correctly, is it open when the...

    Summit 6401 Cam Timing

    My 440's CR is 9.28/1. Initial timing is 20 degrees. The 114 degree lobe seperation angle should reduce cylinder pressure compared to the same cam with a tighter lobe seperation angle, one of the reasons I like this cam.The 114 broadens the power curve, I think that's why people like it on stock...

    I'm losin' it...

    That's good advice, a hill is a good idea. The engine needs cylinder pressure to seat the rings. Dont give up hope on your engine. I bought a ducat 748 with 10000km on it. Went through a lot of oil, like 1l in 500km, that's tons for a 748cc engine. Went and bought the some cheap mineral based...

    Timing?

    Haven't re read the thread but perhaps your timing Mark's are off? Reminds me of a roadkill episode, half way to Alaska in the winter they figured it out, I know in my car having my timing high at idle enabled me to lean out my carb quite a bit, for fuel economy, more heat transfers to the...

    Two types of wire

    Without knowing the type, or seeing it, if the wire that says power and ground is more likely automotive or marine. If the insulation seems tough enough, use that one. Keep your eye on the insulation until your confident the insulation is holding up to the temperature.

    Two types of wire

    More important is what the insulation is rated for in terms of usage, and also meeting the temperature requirements the insulation is likely to encounter. Unlikely an average electrical cable from an contractor type supply meet the requirements,but I have used such type cables in the past...

    Timing?

    Great you have an A/F meter. Do you happen to have a laser temp gun? Quick and easy to measure each header tube just out of the head when the engine is running rough, a discrepancy could indicate an intermittent ignition misfire on 1 cylinder, bad lead or plug for example. A misfire would show...

    Timing?

    This thread made me curious, and a web search came up with this article. Here is a quote. "Most engines will idle happily with an ignition advance of 15 - 32 degrees. This is a very wide range - some engines will certainly not be happy at 32 degrees and others won't be at 15 degrees! An overly...

    440 cam opinion

    Rhoedes lifters would be worth a try with your existing purple cam, you would only need to pull your intake manifold off as well. You would get a lot of your low end power back.

    440 cam opinion

    I'm using the summit k6401 but I have a turbo car so I like it for its rpm range, i also like the older school grind because I'm also using rhoades lifters, and for a few other reasons. The 112 LS on the 6400 will broaden your powerband a bit, good for a tight converter, but will be tamer than...

    Timing?

    My car idles at 30 degrees. I'm using a msd 6530 (programmable box)with a locked out distributor but essentially my initial would be 20 at idle and I'm adding 10 degrees advance because of vacume, so I advance timing at idle, it does run better, my vacume is 20-21 inches at idle, summit k6401...

    440 cam opinion

    The 268h is fine, all over at 5000rpm though, but worked for me with 3.23 gears and stock stall.

    440 cam opinion

    http://www.compcams.com/Company/CC/cam-specs/cam-search-results.aspx?sc=26&sm=By+Engine+Family The comp xe262h. Or the comp xe268h would be the most cam I would try with your gears and stall.

    Water / Meth injection

    Water meth injection won't help with vapor lock and fuel boiling in your carb. If you have detonation on your setup it will help in a non boosted application, or if you have your timing backed of to prevent detonation you will be able to tune for more power. You also would be able to use cheaper...

    Need somewhere to start.

    Wrapping fuel lines rarely does enough, most of the heat conducts into the carb from the intake manifold, a good start would be an insulating carb spacer.You are not running out of fuel, you engine is going rich and stalling out. The fuel is boiling in your float bowls and puking out your main...
