I threw a 360 together and put in a 73 Dart that I tore up the 340 in. It was a basic 360, a set of iron heads, a comp 292 shelf cam, KB shelf pistons, 904 trans with a 4.10 rear gear. The dart is lighter that your car but it ran 11.70's in the 1/4 mile and ran for years, pump gas motor. Dont let someone talk ya into thinking that the 360's are junk. They are alot of fun and will push that B body just fine. Put it in and drive the wheels off. If ya feel that its too slow for ya, put a little squeeze on it and watch it go....
