Hello everyone from Greece
I have here a restored M725 truck.The truck is all original,sandblasted and painted.I'm in searching to gain some power from the engine.I dont care for the originality in some parts on the engine bay.So here are my questions,
1)Can i change the carb with something bigger and better?
2)electronic ignition fit?From what?a military one?
3)what about camshaft?I dont say a dragster one cam but something to gain some power.

I'm saying that because here where i live we have some difficult terain with a lot of ascents.The the truck goes really slow.Please don't spoof me and sorry for my poor english

Thanks
George

There is not a lot you can do power wise to that engine. A lot of guy will add a bigger jet to the carb. there is a intake manifold out there thats made for a double barrell arb but they are hard to find. most people would say drop in a V8 if you want more power.

The Tornado 230 engine in some civilian applications came with a 2 BBL carb. I found one of these and installed in on my M715 thinking I was going to have huge power gains. I do not think it helped at all.

To the best of my knowledge there were never any "speed" parts made for this engine.

Stick with the current carb - the 230 Tornado is a good engine, not a great one, but good. It will have great offroad capabilities, although a little slow. It was not designed to fly down the road at 65mph. Without changing the engine altogether, you're stuck with slow climbs up hills.

The easiest and probably only way to gain power for the stock 230 is to switch to a civilian 2 bbl carb. The 2 bbl manifolds aren't that difficult to find over here. It's harder to locate a holley 2bbl carb to fit. Another option is to replace the ignitor with a civilian distributor with vacuum advance. These are somewhat difficult to locate though. Some guys have put the pertronix ignitor in place of the stock points but I am not sure what part # they used.

Hope this helps.

HEI and a 2 barrel carb does wonders, starts right up, runs down the road with no problems. The HEI requires you to lose the fuel pump/vacum pump but an electric pump with a big spin is a huge improvement.

m-series rebuilds has a electronic ignition kit that replaces the points and fits in the stock distributor. It is 186.00 shipped i think. The hot wire runs to the coil under the cap. Nice little unit. I havent gotten around to doing it to mine yet but its on the list.

do yourself a favor and remove the stock engine and install a small block chevy.
