I picked up a Torker just for startups and such on my PSE, as I will be running a TR and MFI on mine, startup/run-in with a single 1850 is pretty safe. Price wasn't bad and I have a Bridgeport to trim it, so easy-peasy. I had a Torker and a 780 on a 71 Mach1 351C-4V, ran good revved up, but wasn't what you'd call a stump puller- but then the C-4V never was. If you're looking for an actual driver, you can probably do better
