well i had a 10.80 65 coronet and was racing against mostly 12 sec cars and was having my share of red lights with them leaving first.so i put together my 12.00 belvedere,then the well i change this,lighten this,adjust that,i was going rounds with it at 12.00 but the need for more speed led to those changes,now it runs 11.teens.won 2 races in 6 times out this year,you would think i would leave well enough alone.but i'm putting a low deck 512 in the 65 shooting for 10.00.as my wife says[you just can't leave them alone can you].
