400+ HP x 2300 lbs x 11 sec Feasability

Yer right; I generalized that weight a bit (a lot) too much. My cars stock weight WITHOUT me in it is 2360 (if I remember right) and that was with that big boat anchor slant 6 / 904. I think that motor was probably over 500 lbs. When I pulled it out;(without the tranny) the cherry picker was straining (might be bad seals I guess; but it's reletively new) Anyway; I'll be shaving weight; but prolly after the roll bar (cage?); frame connectors; bigger differential; etc; it'll probably be a couple hundred pounds heavier than stock; then with my weight of 185; I'm closer to a ton and 1/2. Is there a HP to weight ratio graph to be had in order to generalize a ballpark figure for performance goals? Seems like I saw one somewhere in my research. Sorry for the failure to realize the true ballpark weight
