Tenmile,
I typically write my forum posts as on email on my computer, then I proofread it, and maybe revise it, before posting. In theory anyway, this makes for a better post. When I revised the post last time I deleted a lot of information.
I realize you’re new to the forum, so you aren’t familiar with the project Tuckers my snowcat buddy, Scott, and I have worked on. My “keeper machine" is called Thundercat. It’s a 1980 Tucker 1644 and has an 8.1 Liter Chevy Vortec engine coupled to an Allison AT545 transmission. This machine is basically the poster child for project creep, and has taken an absurd amount of time and effort. But it’s been fun….
Here’s a link to a video of our first day of testing it:
This is probably my favorite of the videos:
Our other big project is called Snowzilla, and it’s being built for forum member WBuffetJr1, or WBJ1 as I refer to him. That machine is a 1980 Tucker 1643 powered by a 6.2 Liter GM L94 engine, basically an all aluminum LS series engine, and it’s also mated to an Allison AT545 transmission.
The 1544 was acquired in a package deal with a trailer. I wasn’t in the market for another Tucker, but the deal was simply too good to pass up, so I bought it. It’s a 1986, has the optional 360 CID engine, a factory installed Allison AT545 and a front winch. The plan all along has been to keep the trailer and eventually sell the Tucker, after we have everything working to our satisfaction, and have it in “no excuses” condition. We’ll ask a fair price for it, but that said, we have to keep an eye on the financial considerations of any modifications. “Is a customer willing to pay for such and such? If the answer is no, then it’s not worth it. I am a huge believer in the merits of the GM LS series engines. But installing one PROPERLY in a Tucker is a lot of work and the parts required add up pretty fast. My off-the-cuff estimate is about $4K in parts, in addition to the cost of the engine, and that doesn’t include a transmission, or a nickel for our labor.
I’ve been messing around with Tuckers for roughly 12 years and the prices of used machines have risen substantially. If you buy a machine at the right price you can afford to put money into it and still come out okay. But at today’s prices it’s tough. I don’t see many potential customers being willing to spend an extra $10K for an LS engine in a Tucker. That number might evoke “Holy Cr*P, that’s absurd", but having been involved in two LS conversions, it’s actually not enough compensation for all the labor and headaches involved.
The Sniper system is about $1K for the basic kit, but there’s more parts to buy. The master kit is just over $1,300, and if you want to control ignition timing, that adds roughly another $500. We talked about installing a Sniper system on the 1544’s Chrysler 360 Industrial and ran the numbers. We thought we would need to get almost $2,500 to cover all the parts and the labor to make it worth it for us. That was for a complete system including the Hyperspark ignition system. But if you read the test results, you get better starting and drivability, but a Sniper system doesn’t add any power to the engine, and there’s the issue of dependability/reliability. The Terminator system starts at $2,700, and there’s no capability to control ignition timing on a Chrysler LA series engine. For me, given the choices I’d rather spent the extra money for an LS engine and get a truly fantastic engine with some serious power gains. But we have to think of what a customer is willing to pay for, not what we might want...
