i had a machine shop assemble my engine 2 months ago. i supplied all parts except bearings and pistons. i purchased those through them because he was giving me a labor discount since they were so slow. this weekend i found the receipt and ran the part numbers for the pistons. i had asked them to build it around 10:1, instead they used a deep dish blower piston that left it at 8.6:1
The block was decked to zero. I talked to them and he said he would tear it back down and install the right pistons and re balance everything. i already have it completely ready to go to the river, so its a real pita the pull it and start over again.
i plan to run at least 150 nitrous, considered going to 250. is it worth it to pull it and have them redo everything? how much power am i going to lose? will i be able to run 92 octane @ 10.1:1? with nitrous?
