I really like my 318 for now.....if it ever dies I will get into a stroker small block I think....makes sense to me....I have so many new parts invested in the small block.
....although I do have to say....before I got my car I looked at a 73 (?) Duster owned by an older gentleman in Ohio....the body needed a lot of TLC but the 440HP motor he had built and put into that car sounded AWESOME......fenderwell headers and glass packs.
Cant beat that sound....I think my 318 sounds good...I really do....as does the 318 in my Dakota...but like I said, I do love the sound of a big block.
