That would look nice sitting on a stand in my living room.

Build #1 lasted maybe 100 miles if even that. The "331" I thought I was getting turned out to be more like a 317 due to stroker crank that was re-welded to achieve a longer stroke. Shook like crazy but was told it was zero balanced (it wasn't) and I didn't want to bother trying to figure it out.
Build #2 is the short block from CHP as a 347 stroker fully balanced and blueprinted. Transferred the entire top-end from the other motor to this one; ran this for the last 11,000 miles but a leak at the timing chain cover forced me to take it apart and since I was in winter mod. mode, I decided to do a lot of other things - motor upgrade was the first. 
Static compression ratio is actually in the ball park of 10:1. Should be getting 450 HP. Bump stick appears to be a CompCam XE282HR. Heads are Vic. Jr. and Intake is a Vic. Jr. knock-off. It all fits under the hood.
