Not to be too argumentative... but horsepower is really all that matters. Torque can be multiplied and equalized via gearing; horsepower can't.

Most diesels last hundreds of thousands of miles on "compromise" 15W40 oil. Delivery trucks have dozens of "dry starts" daily and still seem to last. I think that the "dry start" is being blown out of proportion. The bearings ride on a wedge of oil which doesn't establish until the engine is...

Jim, The pressure on the back of the valve is a legitimate concern but the area of a circle (valve head) is actually pi*Radius^2. The circumference is pi*diameter. You should also subtract the area of the valve stem (pi*valve stem radius^2) when calculating the force on the valve.

You can replace the stock carb 885-FFG with a more modern 350 cfm holley 2bb. I did this on my gas powered M35 and haven't regretted it.

The early chevy/ gmc block/bellhousing bolt pattern is different than the SBC/BBC/ late model six. However, I do remember reading about someone who mated a 454 to the original hydramatic.

Wix/Napa makes an adapter for doing this. Go to NAPA and look in the back of their oil filter master catalg.

I copy the thread and paste into a word document as unformatted text.

Gerhard, thanks for taking measurements. I need a fan with 1.75" pilot and 2.5" bolt circle.

I am replacing the original REO OA331 engine with a later model REO OH200 engine. The later model engine has a larger water pump and a 4-bolt pattern for the fan. The original OA331 fan fits on to the hub but requires six bolts.

I am looking for a fan to fit a deuce gas engine with four bolt holes. The multifuel fan looks like it might work. Can someone measure the hub pilot diameter, bolt circle diameter, and overall fan diameter? Thanks.

Your rebuilt disty was probably for the deuce OA331 gas engine; they spin the opposite direction and look very similar. IIRC, Vermont Commercial Salvage had reasonably priced rebuilt R6602 distys.

Just to be clear. The only thing that the transmission linkage does is to provide pressure to move a collar inside the transfer case from the forward sprag to the reverse sprag. As soon as the shift lever is moved from reverse to neutral, this pressure is removed and a spring internal to the...

The shift lever does not have to be moved through first to engage the front. If it did, it any benefit would be undone when passing back through neutral.

RE: Air compressor help I believe that the supply and drain line are in the bracket that bolts to the block.

Something to keep the noise down a little and keep the paint on the floor.

Does anyone make a nice, formed floormat for the Deuce?

I think that it would be interesting and not that tough to have dual exhaust and two intakes fed by holley 2300 two bbls. It seems that it is very hard to get a complete burn on these engines. I wonder how much a hot ignition and spark plugs with an extended tip and wider gap would help.

The nova will have a different style engine (194, 230, 250, etc). The GMC engine is 1-7/16" longer than the 235/261 chevy so the (one piece) exhaust manifold will not fit. I think that the two piece cast iron headers can be modified to fit the GMC. You can get the correct cast iron headers...

There are lots of places that make tubular or cast iron headers to fit the 302. Patricks Antique Cars and Trucks sells a cast iron version (may be a modified 235/261); Cliffords sells short and full length tubular header (BTDT), Phillips sells larger diameter cast iron headers nice but $$$...

The original carb is a Holley 885-ffg. A manual can be found here: http://www.tocmp.com/manuals/Carbs/Holley/885/content/MCarbHoll885_1957_B164_index_0004.htm Rebuild kits should be available from the usual military parts houses. If you do a google search, you should also be able to find them...
