TW 170 heads or AFR 165, RPM or Stealth Intake, Holley carb. Solid flat tappet cam for best performance on a buget or spend the extra and go Hydraulic Roller. Cloyes double roller Chain with iron cam sproket. 1.6 ratio full roller rocker arms,Standard volume melling oil pump. That Would be a strong runner on a budget. Just make sure whatever cam you use the Valve springs in the heads are correct.The car has a stock 289 with 53,000 original miles and a remanufactured dbl FoMoCo carburater. Budget wise its really just one piece at a time so any and every idea you can think of would be helpful.
