408 blueprint crate motor by Summit

Stroke your 340,buy all the parts yourself find a good machinist/builder then you'll know what went in it and who did it,those crate(crap) motors are built by whoever...

As for the comment on Summit racing being chevy only..i've spent quite a bit of money with them and i own a mopar,always happy with the parts and service,any issues i might have had were addressed correctly..
