I still have my 360 that my son ran 6.54 with four years ago. That engine was trashed when a tie bar broke on a Comp roller lifter. That block was originally together with a Racer Brown solid lifter cam and Matt wanted a .620 lift roller in it that I had here. I will be tubing that block when I put it together again. I already found a used roller cam and had another stock crank balanced for that assembly. Ported Edelbrock or Speedmaster heads, ported Victor340 intake, 3200 pound car, low 10 second combo.
