Thanks for the comments guys.I understand the business aspect of it ,they need to make money to, but like bob said ,they should have expained that in the begining,then i would not have been expecting money right away. if all works out well and they dont cheat me ,then yes i will definitly spread agood word about there business, and use them again. Plus i could gain much knowledge from the owner, he was an nhra national winner back in the 70`s, so he definitly knows engines
