Thanks for the feedback and again very nice Forum you all have here.
My main concern was ordering a complete assembled engine from someone I don't know, far away and then taking it apart to check clearances and finding things are off! Vs ordering a machined block and all the parts and checking everything myself and putting it together.
Feedback about some engine builders is..."if you buy a crate engine take it apart and double check the clearances and make sure you get the parts you paid for"
thanks again...
