ultimate part score
Mine woul dhave to be the Lightly used 340 engine I bought last year for $1000!! I answered and add from local online listing for a 340 .030 over engine with 3 runs and 500 street miles for $1000 that pushed a cuda down track at 11.50's.
In my car this season it went 12.52 right off of the trailer (first run) and has gone 12.11 @ 111.48 Mph.
The first picture shows it as it arrived the day I bought it, the next is it after installed in my car.
