How long does it take to have a long block built for you??

MoPar makes a good point. Time of year is a lot. I try to get stuff to my guys ASAP once the new year is in. No later than mid March. After that, it could get slower in return time for things I'm having done. My machinist knows I have cash on hand and pay him that afternoon or the next day for the part.

I think the quickest turn around on any part was a block that was degreased cleaned up and honed, ready for me and in my garage in 3 days. Everything else was a known good on it.

Once I have everything, assembly time is just that.
