Long time coming, but I'm building a little bracket car

I've been messing with Mopars for about 40 years now and have had a multitude of performance cars over that time(from 2.2's to Hemi's) but for the last few years I have been mostly buying and selling parts. I found a 1968 Barracuda sitting in a guys yard, been sitting there for years, and I finally saw him outside one day and stopped in. The car is not a show piece and has been sitting in the dirt for many years but I ended up buying it for $400 and decided to build myself a little bracket car. I am basically trying to use up all the stuff I've had laying around for years and I want to build an old school(because I'm old and so are a lot of my parts) 70's style car. Things I already have are several motors, 340's/360's and a couple of 4 inch stroke motors. I have several sets of roller rockers, a bunch of cams (solid and hydraulics) A new set of Edelbrock heads, a MP tach drive race distributor, several intakes (strip dominator, MP-M1, Offy Port O Sonic and a Edelbrock TR5 tunnel ram), several carbs, Holley 750 and 850 DP and a set of 500cfm Eddies for the tunnel ram. I have a 727 we just rebuilt with a turbo action manual valve body, deep pan and a T/A cable shifter. I have an 8 3/4 spool and several cases (no gear yet) I know there are a million different combos and I am just trying to figure out which would be my best bet. I don't want a world beater, just something to satisfy my need for speed. Does anybody think that with the stuff I have I could build a car that runs low 7's or maybe even high 6's in the 1/8'th mile?
