Thanks Franz. Yes, this is a dual fuel set up with mixer over Quadrajet. I am considering removing the mixer and just using gas for a while to see if that improves the ability to rev higher. Also, propane prices are ridiculously close to gasoline right now here in Oklahoma. Propane is currently only...

Does Impco 425 limit CFM?
If I remember correctly the 425 mixers aif flow limit is 425 CFM. This would be a significant limitation to my 800 CFM Quadrajet. Is my thinking correct here or is there something I'm not considering? I'm trying to figure out why my 454 seems to be running out of breath over 2500 RPM. Not that I nee...

Do you know where I could get operating and or service manuals for the Impco? My regulator is a model E and I think the mixer i...

Anytime I am running gasoline, the "out for gas" handle should be pulled out. It is currently running great on gas with the handle pushed in. Do you know what this handle does exactly or why I would be running fine on gas with the handle in when it should be out. Sorry, but this has me confused. I r...

need help with switching procedure
I recently acquired a Chevy truck with 454 V8 and an Impco dual fuel system. I have a panel on the dash with two pull handles and a three position toggle switch. The pull handles are labeled "out for gas" and "prime". The toggle switch positions are; off, propane, or gasoline. My question is, what i...
