soft loc or advanced launch question

L79 -
Clarify your intent with this car. We know it is a street / strip car. Dual useage can be more demanding than single useage. By more demanding, I'm saying what Joe is saying; suspension and / or chassis along with clutch adjustments before and after racing on the track will be necessary (not suggested, necessary; especially with clutch adjusting). Since it appears your using the slicks around town, if your looking to obtain optimum ET at the track, you'll probably need track slicks as well.
So the question is, what are you willing to do? My gutt feeling is your looking for that 9 second street car ET without having to do all the other stuff that would compromise the street duty aspect and making changes at the track. If that's the case, I would suggest adding nitrous or a bigger engine. That way you'll have 9's although the relationship between MPH and optimum ET will always be sacraficed. If you are definite on not making clutch adjustments for your dual purpose vehicle then I would suggest an automatic transmission.

Joe, I have 3 way adjustable shocks in the front. I have them set tight because I thought it would put more leverage to the rear tires.(from baseline suspensions info). I do have two sets of slicks for it. Car is really set for racing and not a cruiser. I drive it to where we race on the street and hang out. I dont think the 4 link is far off from a good setting. I went by what the guys at Chris Alston recommended. I think I will lower the air pressure and launch it at 6000 to see how it reacts. If it doesnt work properly I'll go into the 4 link a bit and get the lighter springs for the plate. Eventually I'll got with a fully adjustable clutch from Rob.

Jeff, I do want to crack the 9's because I see the mph and know what the potential et is. If I didnt have the mph I wouldnt care about going that fast. I dont want a 9 second car just to say I go 9's so, nitrous is out. I pride myself for having a fast streetable pump gas small block though. As for the automatic. All my friends who run automatics are constantly telling me to put one in. I've been runing stick cars since I'm18 and wont give in. I just love pulling and pushing that shifter. Someday I'de like to try one of those Tex racing clutchless trannies or a jerico.

Thanks to all that responded and If anybody has anything to add please feel free to. Thanks again in advance.
