That has to be an old Boeing truck. They had hundreds of 620s in the 70s and 80s and most, if not all, were Propane for running inside the plant buildings.

 

I have a propane carb and manifold set, but I didn't get the propane head that went with it because the guy wanted too much for the head.

I remeber I had a little 68 Datsun 520 back in 2001. I forgot about that little truck. I saw it @ a jobsite in South Seattle with a 4-sale sign. It was too cool looking and I asked the neighbor whos it was. It was his and I bot a battery and drove it home for $100 (no brakes:eek:) He told me it was an old Boeing truck. It had a serial # under the hood. Your mention of Boeing just reminded me of that.:rolleyes:

Cool, the trucks the drive around now are little d50's and mitsubishi's

Out of curiosity,what would be different in the head to make it run on propane?

One by one we will save them all :D

 

 

The biggest problem with propane is it has even lower BTU's than gas..... 98,000 if I remember correctly. hhhmmmm I will have to figure out what it ends up being per mile compared to gas

True but propane has an octane rating of 104, so it would be sensible to extract as much power as you can by raising the compression ratio. This narrows the gap between gas and propane quite a bit. Cleaner burn, less emissions, longer between oil changes, cleaner motors.

I saw that earlier today looking for 521 stuff. I was trying to think of a reason/excuse to buy it, but I didnt have one. It's cool though! There's a diesel 720 up right now too, kinda beat but still cool.

there is a 620 at the old jims auto wrecking in poulsbo. at least i think it was at one point, all the stuff for it had been stripped out of the engine bay by the time i saw it

i see the topic of compression has been discussed :)

 

i had been considering modifying an L-series to run on LPG or CNG, but hadn't done much research. the folks at hybridz.org had a few links in one thread...

 

anyway, a turbo + 10:1 compression, anyone? >:)

Duh, duh, duh, duh.......Duh!

 

If you wanna hang out you've got to take her out,

propane

If you wanna get down, down on the ground,

propane

 

She don't lie, she don't lie, she don't lie.....

Propane!!

 

Duh, duh, duh, duh.......Duh! (sorry, eric)

Are the propane slower than regular gas?

[e_racer1999]

^inherently, yes. as was mentioned fewer BTUs than petrol. but the thing is that most current/prior propane powered cars are only LIGHTLY modified to run LPG, ie small carb/fi replacements, no modification done to raise compression.
