Re: 04 chevy G3500 6.0l

Welcome to the board!

It would be helpful if you were specific about which system is installed in your van.

Re: rebuilding engine - some questions

I am far from an expert with respect to rebuilding engines but my understanding is that quench is used to induce turbulence in the combustion chamber. The greater the turbulence, the faster the flame propagation. The net effect is a reduced need for ignition advance. Therefore, the ideal quench woul...

Re: How tall is an IMPCO 425 compared to Rochestor

I measured my Quadrajet's height to be 3-3/16" and it has a 1/4" gasket.

Re: Closed loop system install

HI Davey54. Welcome to the board!

The SV is installed in the secondary test port in the side of the converter. With the vapour outlet pointing downwards and the cover facing you, this is located at about the 7:30 position.

Re: Propane tank won't fill after running on empty

While it's possible that is the bulk tank is substantially cooler than my car's trunk-mounted tank (which is typically parked in my garage), I would expect that, within a week, the bulk tank should approach ambient temperatures. I find that my local station in Fort Erie commonly has trouble filling ...

Re: Propane tank won't fill after running on empty

I have sometimes had problems filling the trunk-mounted tank in my car at some propane stations during the summer. My local propane station often has this problem with other cars too and the attendants believe it has something to do with the temperature of the tank, especially with underbody tanks e...

Re: need help improving my mpgs, getting 6mpg

Welcome to the board! Ignition timing is important to both power and fuel economy. It would be very useful to chart mechanical and vacuum advance. A setback (adjustable) timing light would handy but timing tape will work too. Do you have a the vacuum advance permanently capped off or were you just d...

Re: Propane motorhome. Pease help

Welcome to the board! I think you need to re-read C3H8's post. A motor fuel system requires LIQUID-withdrawal rather than VAPOR-withdrawal from the tank. The Model E is a device that vaporizes the fuel and regulates the pressure going to the carburetor. If you use a BBQ cylinder to supply your 440, ...

Re: Cant get impco 300a to run consistantly

This might help: http://www.allpar.com/fix/EGR.html With a timed EGR vacuum port, you shouldn't be getting any EGR at idle. Are you sure that you've connected to the right port on the carb? Maybe you can make the EGR port a bit smaller to restrict exhaust flow. The other option would be to leave it ...

Re: Cant get impco 300a to run consistantly

If you give me the diameter of the pulley (or balancer) where the TDC timing mark is located, I can work out the distance of the your total timing advance from TDC. You can then mark this with paint and see where your actual timing is relative to your target.

Re: technocarb setup questions

Since it maintains a stoichiometric fuel mixture, it should be reasonably fuel-efficient.

Don't forget to optimize the centrifugal and vacuum advance for optimum power and efficiency.

Re: technocarb setup questions

I thought that since you didn't end up buying the system in the other topic, there was no longer a need for that information. What kind of information do you need? In the other topic , you mentioned that the system you were bidding on used a Landi-Renzo converter. I believe this is a TorqeGas system...

Re: technocarb setup questions

You have an older version of the offroad 4bbl carb kit that was featured in Off Road Magazine. It is a feedback system that uses an O2 sensor and RPM inputs but does not require a TPS. You will need to bolt the mixer to a throttle plate assembly. Since you already have TC210 Scan Tool, you should ha...

Re: technocarb setup questions

Unless you have the 4bbl off-road carb kit, Technocarb kits that used the EFS600 controller were model and application specific. Can you post a photo of the label on the back of the controller or email it to me along with specifics about the vehicle you want to mount it on? C3H8 is correct about the...

Re: fuellevel senders, reverse operation?

Your LPG tank may be equipped with a Mopar level sender (70-10 ohms). The simplest solution would be to replace it with a 0-90 ohm sender to match your new fuel gauge.

If your tank uses a Rochester Gauges level gauge, you can use a 0-90 ohm TwinSite Junior sender (PN P5628S02537).
