Just as slow as before my mods..

I bought this Demon with 318 stock everything, 3 spd tranny and weak rear end. I invested over 24K in upgrades and it still drives the same. Tires won't even chirp at takeoff. Would an MSD ignition significantly increase power? What's missing in the recipe?

Upgrades below:
Rebuilt V8 318 engine and heads/valves w New 4 barrel AVS2 carburetor, New performance cam, New aluminum performance intake manifold, TTI stainless headers/exhaust, New high amp performance alternator, New performance aluminum radiator w dual fans, New gas tank w high pressure pump, New 3sp w OD tranny, New Dana 60 rear end w 3.73 gears w trac loc

BTW, I'm not a wrench head anymore and don't have a garage with snap-on tools, lift, or even a spanner wrench. Thanks fellas
My standard reply to a friend, who is always looking to "fix, or improve" something, no matter who does the work, then is terribly disappointed: "You should have F&$@?! left it alone!
