DAM!!!!!!!!!!! Well, guys, I dont know what happened yet or why, but I can see a piston skirt just above the starter. I made 3 test runs, thought I heard a funny noise, brought it up to 4000 rpm, and BOOM!!!!!!!!! I could hear pieces bouncing off the bottom of the floor boards. Performance before hand was with the drag radials on back (back-halfed) at 9 psi boost, 83lb injectors (I didnt even have the 160 lber's in yet) 35 mph roll 2nd gear, car went sideways with 2 ppl in it, yes we were on pavement, lol. 5500 rpm was all that was attained. This rod blow out is most disturbing... Bruce at Aggressive will be the one to disect it to see what happened.. I will let you all know for future refernce on your builds as to what the cause was. I'm down to 1 block left, this one better work!!!lol. Have a good one guys. Mav...
