I might take on a project this winter and have a 440 silver bullet in mind not too far from me. I'd like a single skunk but I can't be too picky. Any advice? hard to find parts? I next to nothing about the tnt's.

I say go for it! I know a lot of people don't care for them, but I've always loved the silver bullet. From what I've read/heard they are all dogs and the best performing one was the 294.

Sorry Rock, Little slow getting onto this. That's a good sled IMO too. Bullets ran in 73 only. People dubbed them as silver slugs but that was just because they were the heaviest to date at the time for the same sized engine. They were forced to find ways of making them quieter so they added a lot of shrouds and such. That 440 engine was the first big fan, and made more hp than the 72 did. Reason for it was the pistons were now ported. In 73 that engine was steel sleeves and no chrome rings or anything like they tried a few year later in the "Type 440". Same chassis as a 72, just more hardware welded to it. Better ski-legs, better tie rods etc. Fiberglass hood, same windshield as a 72. Same old bogies, but the sliders were very heavy - but considerably better than the split rail slides that were 70-72 (I would suggest bogies). Should be the same gearing as a 72 too which is 18/34 I think. Lots of plastic pieces on this sled - the engine cover and the hood grill for example. They often are cracked or have pieces missing.
The gas tanks were different - side fill neck thing instead of in the middle. Those tanks were only a 73 bullet thing, so if its cracked or needs to be replaced then its a pain. The normal center fill style is more popular and does fit... but its a pain to fill up because there's no flip door on the hood. So you use a funnel & practice your aim... and you're off to the races.
Still IMO you can't go wrong with an old easy-to-fix sled like this, no matter what the engine. If it were that smaller 294 with twin carbs I think that alone would be reason enough to want the simplicity of just ONE tilly to tame at a time lol. Lots of parts will interchange with other years.

olyman, I doo not think the 73 - 440 bullet engine had boost ports in the piston. The piston was a little different crown from the 72 and had a single "L" ring ( I think this is correct), and yes has big fan. The type 440 started in 74 and had boost ports. I agree, the 73s really had as much or more power in the 340 & 440 for 72 but they were so closed in due to noise regulation. They were usually running on the verge of over heating and no 2 stroke puts out power in that condition. Pulling the dash / shroud off usually helped a bunch. Bones
