way too slow at drag strip! what should it run?

Well the reason I ran race fuel is BC I'm running around 188-190 cold cranking psi . I broke the engine in on 93 Oct and could only set timing by ear bc my timing light had the wires pulled out of it. ( someone left the wire in a alt belt). After a day or so of driving I checked plugs. Started to show little black spots so I ran 50/50 93/100 to be safe..
Traction. Yes your right about that. The Dakota will be running caltracs and mono's with 29/14.5/15 slicks.
So I should be able to hook up.
The reason. For the 4.88's is BC that would put me mid to low 11's mph going through traps at 6500-6600 rpm .
This won't be any street.. Only bracket raced and trailered. And I figured I can always run a 31-32 slick if needed.
The 8" 4500 was recommend to me by the tech at Dynamic converters. Oh and rockers are 1.5 ratio
