When I asked Franz about using dual 425s and Dual Es he told me my single electric block off would flow plenty. Idk I should go back and see if I can find that email. Welding a new bung into a pressure vessel requires a you have a "R" stamp to meet ASME requirements in this country and I am betting ...

This engine is a starter killer and I finally got pissed over Christmas and tore of the inspection cover and transmission support rods and set the clearance on a brand new starter. While under it I notice is had a massive oil leak. I started with the valve covers but after pulling them is was obviou...

Holley square bore. Started as a 670 cfm truck avenger but has different metering blocks now to allow main circuit air bleeds which the it didn't have from holley.

So, I have seen the suggestion that when you have a Quadrajet that the secondary door spring adjustment may need to be a bit lighter than it would need to be when the carb is on gasoline. Do you guys see a similar effect with a holley vac secondary? I wonder if I should go to a yellow or similarly l...

ok, I will just transfer it out of the 1 & 20 I have when I get it swapped on. Other than a electric block off that was doing odd things limiting flow and not opening despite "feeling" it open, the truck is running on lpg and doing fine. It does feel a bit soft up top but goes down the road fine. I ...

So I it running with a 1 & 20 off a old forklift bottle so I can go fill my in bed tank. I did buy a 50 & 70 off of Ebay and was initially sent a Feed Back 1 & 20 instead. I complained and was sent a 50 & 70 that is also a feed back but I had my local propane dist order the right fuel valve. This on...

I fully understand the concern heater blockage could cause reduced flow though the vaporizer. I will be sure to plumb it on the inlet side and see if I can find a "H" to assure flow. I found my second model E had a orange spring so that should be good. I soaked the E I am rebuilding over night in a ...

I was thinking about what you said about the heater line. I wanted to put the vaporizer in the return to try and prevent over heating the propane, not so much a concern about heater output.

I have a 20 and a 50 is on the way in the mail. Putting it in the supply makes perfect sense.
I live in southeast Nebraska.

I have done a few dual fuel systems on newer 02-08 Silverados and my 79 K30 rock crawler has a 425 on it's lpg only 454. I was given some more lpg stuff the other including a 119 gallon tank, 2 Es, 425 and a 300A. Since my new job has me driving 90 miles round trip and in an attempt to slow the rust...

Well I have all my parts collected and I need a few tips. Should I attach my Es close or directly to the 425s? I noticed on my single if I roll out of the throttle then back in my truck will cut out now but the hose is 2' long. When I get back into it, it runs great. Thinking that the hose length is...

Because I have received a lot of information from this site I will do my best to give back. I finally have the first step of my K30 done. Gen VI 454 short block with a marine roller cam 224 duration .485 lift 114lc, with large oval 781 heads, performer intake, 7.8 to 1 compression and a single 425 l...

I ment one lock off. Planning on 2 Es and 2 425s. May not be the best parts but I already have half of them.

I get bored with life sometimes, so I tend to do stuff just to see what will happen. I am installing a different 454 in my k30 using a performer and and a single 425. Nothing too crazy, stock gen vi short block, mercury marine cam 224 duration 450 lift 115 lobe sep, 781 oval port heads. I know it wi...

Just one 425 and one E. It is all done at a very low rpm. I read your post and once I get the EGT deal figured out I think i will be looking to see if a second E wouldn't make my fuel more steady. We could get it rich enough by screwing in the mixture screw but it would over richen the bottomend. I ...
