I called my warehouse today about a Dart Big M block for customer build on big inch Chevy--they had two deck heights in 4 bore sizes with two main cap material choices IN stock Free delivery starting around $1600 and..USA made--My parts dealer drop shipped from one of their other warehouse direct to my customer for FREE I have had lots of fun with Mopars and raced one for over 20 years but I am racing a Chevy now in my vintage front engine dragster-- Mopar was fun while it lasted
