I had the block up already once before, but had second thoughts about selling it ,now I'm really letting it go. Specs: cp 9:1 pistons over 600 alone, eagle h-beam rods, fully balanced micropolished crank, brand new oil and water pump, and block gaurd. The motor was built by HiboostMotorsports in port st lucie. It has a tapped oil pan ready to go. The block only has 1200 miles on it. I'm asking 800 firm. No lowballers I will post pics l8ter. I am selling because I'm going for a bigger setup, motor was tuned by Columbia made 426 hp.
