Proven Combo's for 12s

[MrHorsepowerLSx]

I figured this would be good for everyone to read and put info in here on how to have a reliable 12 second DD that's not a total kill on the wallet. It seems that everyone is looking to be in this 1/4 mile range somewhat and have there ride be street able at the same time. If anyone has proven combos please list what the supporting mods are. Please Include tire type and size ( ie drag radial,stick,street tire, etc.... ), Wheels and size rims ( steel, aluminum, etc...), Traction devices ( cal-tracs, slapper bars, spring clamps, etc...), gears, motor ( if swapped ), heads, cam and specs, Valvesprings, pushrods, headers, Exhaust setups ( single 3", true duals, etc....) trans work, Stall converter ( Size and type, also what brand, and if it is lockup or not), fuel octane rating, HP/TQ numbers at time of pass, dyno sheets if available at time of pass. Also include body style, year, weight, and any weight reduction that was done. Try and list as much information as possible to help everyone make " decisions " on HP and time slip goals that they may be trying to meet.
