Re: Holley 2300

A couple of things to consider. First, the Holly 2300 is a beast with 100lb/hr injectors. The typical Pinz engine EFI conversion uses 20 to 30 (MAX) lb/hr injectors. I run 24 lb/hr Delfi injectors in my 2.7L 710 with the Beck manifold. The issue with more flow than necessary is control, the duty cyc...

Re: Reenforced Aluminum Sand Ladders

Kind'a with Mr. Zero on this one. As a sand ladder there are cheaper and useful alternatives such as Maxtrac. As a bridge it just does not look robust enough. The manufactures WEB site here https://sandladder.net/ , I think the test kind'a shows this would be a bit dicey as a bridge. I went with Fib...

Re: Dangers of Bed Liner Material

Spectrum would be a good choice. That’s exactly what I used in my 712 tunnel. Took about 6 coats to get the desired thickness. The longer story is that I tried Mass loaded vinyl prior to spectrum and it lost adhesion on a very hot day and my Fan belt had a wonderful time eating that stuff. Good I ha...

Re: 710K failed emissions

Well here's hoping that your funky fuel cutoff solenoid is your primary problem :wink: In any case one byproduct of combusting gas is H2O. So when you start up initially, it will be seen on the ground and dripping from the tail pipe until the exhaust system gets hot enough to vaporize the H2O -- the...

Re: 710K failed emissions

Hmmm, I do know one thing from my own experience, if fuel can bypass the acceleration jets or emulsion tube then raw gas goes into the intake and raw gas will not ignite. Earlier this year both my acc jets got plugged and raw fuel was leaking right at the base of the jets, I was nearly running on 2 ...

Re: 710K failed emissions

Hmmm, smokes? And worse with advanced or retarded timing.
Does it continue to smoke after she's completely warmed up?

I'm grasping at straws at this point. But with your results 4X
higher HC's at idle you should smell it in the exhaust.

Re: 710K failed emissions

Looks like a clean ignition -- if anything, possibly running lean not rich. Not what you'd expect with the HC readings you had esp. at idle. Although on the other side of the combustion chart, if you run excessively lean, you can fail to combust. Following that hypothesis, a vacuum leak that could e...

Re: 710K failed emissions

OK, well wrt AFR I was referring to Air Fuel Ratio. But the exhaust sniffer guys probably deal more with contamination levels e.g. PPM. Is there any indication of running rough in idle or hesitation when you goose the engine? Might be an indication that one of the carbs is at play, hopefully the plu...

Re: 710K failed emissions

Hydrocarbons in the exhaust implies unburnt gas. Likely running too rich,
or misfiring on a cylinder. What do your plugs look like? Does the report
indicate what the AFR was and at what RPM did it fail? I presume running
speed. AFR under 12 is rich.

Re: Can you have 2 24v to 12v converters?

If your converters are connecting to the Top battery 24V, and NOT the midpoint 12V, then with the Battery ground switch OPEN there no possible way for any power to be present anywhere -UNLESS- your Battery Ground Relay is stuck closed or power is getting to it from a sneaky path then then when the G...

Re: Winch breaker and cut-off switch

WRT a switch, I guess it all depends upon how much of a paranoid you are :( My thought process is, well, what could go wrong even if not that likely. I also tend to be a magnet for "sh*t happens" so that gets me more in the belts and suspenders camp. Thus the Switch on the Battery side. As...

At one point in time he was making Fiberglas tops as well as metal. I have one of his sheet metal tops
on my 712, now a MK.

Re: Winch breaker and cut-off switch

I think it’s a good idea to have the power switched and not “hot” at the winch.
I put a switch behind the drivers seat parallel with the ground switch on both
my trucks. If for what ever reason a wire got shorted the default would be off
and no risk of drained batteries or fried cables.

Re: 712M won't start. Looking for ideas.

Oh! I missed seeing your earlier posting with your measurements -- sorry bout that. Soo....you do have 24V at the coil positive terminal and the Ballast is 4.5 Ohms. It sure does look like all things are reasonable from that perspective. It remains very odd that when you connect the control wire fro...
