Wait, hold on. 3 1/2 months and no parts after you sent $6000? What are you waiting on? Did you buy the blower and his exhaust? When does he plan on sending the parts? This needs to be remedied.

Granted he could have communicated much better some one need to teach those skills to him but I will not hold a grudge he said he had serious family matters to attend to in reason for the seriously almost 4 month shipping time October to last week so if that's true I'm not mad at him just for the record

agree with griff,,,,only go 30 first time,,,then u could still go another 30 if u had to...if u go 60 first time,,u are pretty much done with that block...people have bored bigger than 60,,,plus not a good plan.

i actually had a 454 bored 125 over..makes a 482,,,yea the block lasted about 3 trips to the drag strip...cracked several walls,,,block was now junk.
