My V8 conversion i wanted to do for 5 Grand, came in at 6 grand but included black interior with dynamat and new carpet, lots of chrome, brake upgrade and a satin black paint scheme. Did all the work myself but it'll still cost me minimum $2200 to engineer and roadworthy. I've said it before that in my opinion it's better to try something and fail at it then not try at all. I like the road less travelled.
