I purchased a engine block for $375.00 on 6/15/10. I didn't hear from Comstock for a month. I called them. Talked to a Lauren White about the engine block that I had purchased. She informed me that the engine block was not available and that Comstock would refund my $375.00. I called again and talked to Lauren White. She informed me that refunds are sent out on Monday's. Todays date is 12/21/10. There has been alot of Monday's gone by with out a refund. I realize that I will never see a refund. DON'T BUY FROM Comstock parts web site
