i have a 93 silverado with a 383 roller motor pushing about 450 hp. 1 was running 14.9 to 15.2 with the stock rear end unit in it. i put a brand new limited slip 4.10 unit in it and now my times are slower. what is wrong and/or what can i do? i just cant figure this out. thanks in advance.

How do your 60ft's compare? What are your trap. speeds? My guess would be your running out of gear.
compare your slips, for speed, 60 fts, 1/8 mile and so forth.
