I have a mild 292 (194I/204E;.464I/.490E lift cam, 4 bbl headers, HEI) in a 1966 shortbed stepside pickup with a 4 speed. I also have an 11 inch clutch (stock was 10 inch).
With no load in the bed spinning the tires is as easy as revving to 2k and letting off the clutch - it's effortless. That's on dry pavement. I'm not sure what would happen if I revved to 4k or so and "popped" the clutch but I'm
sure the U-joints won't like it!
