Stop in for a cup of coffee
Stock 72 318 short block (fresh rebuild from back in the late 80's), 67 318 heads ported with 1.88" intakes and 1.60" exhaust valves, 8.6 compression, windage tray, medium cam, Edelbrock true roller double roller timing chain, Rhoades lifters, LD4B intake, 600 Holley vac secondary, with stock 273 early A exhaust manifolds so it will fit the 66 engine compartment...
