My 80 Volare will become a perfect clone (everything covered but the v.i.n.) of 80 R.R.. 318 is '82, heads are '80 360, T.Q. & intake are '79 318, headers, 340 cam, low gear 904 from '82, police Dip. 8 1/4 posi (it's '83 so I think 2.94 and I can do 3.55), the police leafs/sway bar and I get rid of rubber isolater stuff. With 245 60's on the back I want 15.2 quarters and with 235 70's on the back I want 20 m.p.g. on the freeway. Am I asking to much?
