'71 Slant Six Dodge Pick-Up

Post by Daddiojoe » Thu Feb 01, 2007 10:01 am

My goal is to convert my D100 to propane sometime before summer. Currently it has a 2-bbl 225 c.i.d. slant six with 2.25" exhaust in front of a 727 automatic transmission and 3:23 rear.

I'm about to go to Dutra Dual exhaust and will eventually shave the head .050 to raise the compression ratio. I have a spare head that I plan to someday port, and raise the compression ratio with as well.

The ubiquitous '63 Rambler article has been my model so far. After calculations, etc. I'm thinking I need:

Impco VFF 30 filter/shut-off valve

Impco Model L convertor/regulator

Impco 125 mixer

I'd like to use the throttle body from my Carter BBD and make an adaptor.

I've got a tank that has been approved and stickered. It's one of those two-cylinder tanks designed for the front of a pick-up bed.

I'll also be needing a fuel gauge.

Any help on getting parts would be appreciated. Also comments on propane and slant sixes.

Adaptors for the slant six are available without having to machine your own. Proquip our of Canada can help at 403-692-9388 or check one of the local conversion centers in your area that sell IMPCO equipment. This was a very common adaptor at one time. Difficult to remember but I think your looking for an AA3-53. I need to check the old books. Also check with Franz in the Propane forum section. He's in your area and can probably find one of these.
