Back in the early 90s we had a 68' Barracuda @3380# w/driver....
440 block 4.375 x 4.15
906 ported iron heads
.590 MOPAR solid cam
M1 intake gasket matched w/2in spacer
Holley 9375 1050 dominator
BME rods
About 11 static compression w/flats
2in fenderwell headers
727
9in "J" converter
4.56 Dana
SS springs w/inboard
Mopar rear shocks.....Koni SPA-1 fronts
SS Hemi style scoop
31 x 12 Firestones
Drove the wheels off the car on the street and only had about 15 runs in that trim before we switched to 440-1s, a solid roller and good headers.
Raced it on cheapo Cam 2 110 because we had a station 3 miles away that had it at the pump for $4 a gallon, so it drank that, mostly......but it would drive around on 93 pump with no issue.
In decent air at ATCO, 10.06 @135+.
Most fun car I've ever owned......cheap to build and low maintenance.
It doesn't take much to run 10.90s if your in the 550+ range and your converter and gear aren't in left field, but 3400# might be light for your car, unless you've taken some steps to shed some weight.
