Hi room - am researching which way to go with a 350 Crate engine for my 46' ford 2dr - has anyone had any experiance w/Smeding Performance engines? or Jasper? and how do they compare with all of the guys who are selling the GM Performance crates? (Jegs, Summit, and GM?) and what about Edlebrock? Many thanks in advance for your advice and knowledge - Charlyg
