318 build #2 "cost minded" for the '74 Duster
My 73 Duster full street car with buckets and other weight adds like rear window louvers, speakers with heavy magnets, Demon scoop, and DC trunk spoiler went low 9's in the 8th mile.
Fresh LA 360, stock 904 with 270-ish DC cam, 360 manifolds with 2.5" duals and 3.23 SG 8 3/4.
IIRC that's a low to mid 14 sec 1/4 mile.
EDIT- also had iron 4 barrel intake, and working AC.
I want to say 89 MPH.
