Kinda torn over "tyres"

[Idaho]

White Demon from New Zealand (see next post) stuck in my head (thanks Chris for helping find it). Hope he doesn't mind me posting from the article.
Would love to achieve this look with my Demon project. Was glad to see he retained leaf springs as I'd like to stay as simple as possible (cost).

Trouble is I also want to burn up some rubber, break things loose in 2nd, 3rd. I'm planning for a Magnum 360 in 450 hp range, A-833 manual trans. He has a built big block 440. Obviously he can light them up but even with that mill, I'm not sure he'd get 2nd or 3rd gear rubber.

His "tyres" (from below): Hoosier 31×16.5.15-inch Pro Street Radial drag tyres


So... how big do you think I can go and still light em up????

:burnout:
