Ignition Upgrades M37 Vintage Off Road Wrecker 

Even though changing the ignition made little difference on the dyno I still think it was worth doing. You made a good point about the overall power, it being good for the time it was built. I look forward to the rest of the upgrades you have planned Steve. 👍👍

I love it when you say “ it’s that easy” . On my couch it does seem easy. Otherwise maybe not!

Always interesting to see a before and after Dyno analysis.

You should enter your truck in the Matts Off Road Recovery Wrecker Games.

I figured a flathead six wouldn't make a lot of power, but this makes the flathead six Power Wagon look like a 383...

Pertronix is the Bomb...

Great video ! but at 6:30 that red wire is going to eventually get rubbed through.

i think i see a little coolant dripping from the upper rad hose at the radiator, just fyi in case you were not aware of it

what a great old truck, sure beats chopping it up and turning it into refrigerators or worse

Next time…take the points to a jeweler and get them to coat the contacts in gold. No more corrosion. Good to go.

It still has more power than my '78 VW Bug!

Neat old truck Steve , Loved the video , HAPPY NEW YEAR MY FRIEND !!! How about a Best Of 2023 vid !!!

Excellent video Steve :) also very good information and interesting to ! Looking forward more videos too soon!

Where does he get those wonderful toys?

If I had that and wanted to keep the stock engine I would increase the compression ratio as well put a better carb and ignition and have less things on the engine. For me personally I would put a diesel in it and lockers.

Petronix ignitions are about drivability! However your power wagon is crying out for a diesel swap!

Surprised that there was so little difference

the small capasitor is for radio noice.. the weeeeeeEEEEeeeEEEEeeee radio sound filter the big RESISTOR is a old radio sound dampening too to not make sparks go klick klick klick klick when spark plugs ignight... so please ask a electro duude about the spark sice if you remove set RESISTOR and sign on for the MATT OFFROAD WRECKER OLYMPIC.. even you dont partisipate you can display you truck and worst thing happening som 1000 subs.. respect.. i realy hope for a huge turnout of wreckers on display so the fans can meet you..

Need loc-tite on the mounting screws. Vibration can work those screws loose and cause all kinds of missing and lousy running. Ask me how I know!🙄 It took me a week to track that one down!

Something's wrong with CB Points pivot/fulcrum ... Duceillier Points I believe.

on Nicks garage he sets his engines to 34, 36, 38 degrees so yours at 2 is different. state the torque ? 180 torque was it?

Nice. Great demo on changing to electronic ignition. Is Petronics your go to equipment?

When you drilled out the rivets you seemed to have disconnected the vacuum advance rod as well. Did you manage to reconnect it? It wouldn't affect the max power but might affect part throttle behaviour.

The screw that you were having so much trouble with can be loosened with a wrench. It is a hex head .

Hmmmmm, I guess you are seriously into that uhhhhh patina stuff? I would have cleaned the distributor myself? Did you check to see if the vacuum adavnce actually works & how much adavance it adds and just not show it?
