I just called to check on my mono block to see when it will arrive and they said it will be shipped out today . I asked the guy about the work that was done and he said it was stripped and reniked no welding. So I asked about the crack in the intake port nope did not do any welding on them. Lucky they have not been shipped yet so he went and retrieved the box and guess what it is cracked . So back they go, I even filled out a work order and explained what needed to be done . When asked what happened they said they would get to the bottom of it . So for you guys that have sent out cylinders you better call and make sure that they have someone that can read do the work.
