If it's just the springs you're after and you know what you want, go to any number of spring manufacturers and have them send you some. Likely there is a min order quantity. I run a lot of older equipment and the mechanical fans on some of my Cats have a coil spring to keep tension on the blade (they're reversible if you push the blade into the hub and twist it) and that spring is NLA from Cat so I had some built. I think it was 500 min order from the place I used. Had them fairly quickly tho which surprised me for a custom order.

I agree, there is still a market for them. Especially with the semi-finished inventory and custom "lettering". They may not sell as fast, but I don't think you would go wrong doing another production run.

The only 2 things I currently run on a regular basis with a carb is the boat and my 73 Camper Special. The 73 has headers and AC so the engine compartment gets toasty. With a plastic carb spacer I've never had any trouble even in 100*F weather. Before the spacer it would heat soak and boil the bowls when it got in the 90's. After the spacer never had an issue. Tried insulation on the fuel lines, etc, but the carb spacer is what fixed it.

The boat was fine on non-ethanol but with E10 in it started having boiling issues. Swapped to an aluminum intake and that helped a ton (ex crossover blocked), but again, after a 1" plastic spacer haven't had an issue in 3 or 4 seasons no matter how crappy the gas is.

Better: let's all pitch in a few dinaro, buy a later model Camaro and have Jay dump in a FE for a dragstrip killer!

Not an ideal drag vehicle, but I have a somewhat rusty 55 series II Chevy pickup out back I started putting a 429 CJ and C6 into just to irritate the bow tie buddies.

I think you could make the Sniper work, but it would take some time to sort out. A better choice would be to run a Terminator, MSIII, BigStuff, something you can run set up AlphaN to work with that cam. A little work up front but probably better in the long run. Sniper would be easer to set up but likely wouldn't ever be quite dialed in.

For semi and agriculture I truly don't understand why nobody has gone diesel electric, like a train. Arguably one of the most efficient ways of transportation.  And something I would interested in owning.

Seems its either all IC or electric. Hybrid is being looked over anymore.  No way would I go with a 100% electric vehicle, but that's my prerogative.

There are a TON of hybrid commercial vehicles on the road. We have a fleet of over 1400, currently we are 100% hybrid. They SUCK. They are un-reliable and literally double the cost in maintenance on a yearly basis's and over double on a life-cycle cost versus the identical equipment spec'd with regular diesel power. Not to mention the quadruple cost to purchase new. But, to help offset the cost is the fuel mileage increase of the hybrid. We are currently saving .63 MPG average over the 1400+ vehicles. Subtract that from the huge increase in downtime (if it's in the shop your spending money instead of making money) and the additional maintenance costs and it's a money loosing idea. The ONLY reason we still run them is because of politics. If it wasn't for ESG scoring at the Bank and the political pressure we would dump these in a heartbeat.

I'm sure the counter argument will be it's just because the technology hasn't matured. Well, we've been running commercial sized hybrids since 2003 and the reliability and cost to maintain and operate has NOT gone down 20 years and 3 generations of technological updates.

Also, ALL of the battery packs these use are either manufactured in China or are manufactured here with materials from either China or Russia. The average battery life has improved from 5 years to around 6.5 years. Let me just say, there isn't really any industry set up to handle these batteries and the ones that are "recycled", yeah most of those get shipped off shore and are burred in a field in Malaysia.

I've also seen several people fried from EV's and hybrids, both in accidents and due to unfamiliar maintenance procedures. 

I'm not a fan of hybrid or 100% battery stuff from an environmental or trade standpoint. I LOVE them from a maintenance stand point. The OT has bought me a LOT of nice stuff and contributed nicely to my retirement fund. We've also had to hire drastically more people because of them. Roughly the same fleet size in 2003 and we had around 240 mechanics, by 2007 we were around 290-310 to keep up with the additional work. Our test fleet of 100% battery stuff (on the commercial side, we've already had issues with our automotive fleet that's in-service) is likely going to be around half again as much maintenance increase as we saw with hybrids. With the increased disposal issues to go with this stuff.

I have a 96 F150 shortbed 2wd with a 300 (last year for the inline) and a 5 speed. It gets 18 all day every day (would get 20-21 before the rear gear change). It's no race car, but it's dependable and for what it is I'm happy with a consistent 18. After a early 2k's E150 spindle and brake swap, a little more gear and it's also a lot more fun to drive.

Granted it was a brand-x small block, but I think the results are fairly universal. The amount of money you'd spend tayloring the engine to get max mileage never returns on the investment. Build a good engine and spend that extra money on chassis upgrades that will help mileage.
