Is it worth it?

Depends...are you ok with spending countless hours and thousands of dollars? I am near the end of a complete powertrain swap (New MOPAR 360 block, heads, upgraded from 904 trans to a 727 trans, new driveline, new DANA60 rear end (because the old trans and rear end did not hold up more than one weekend). So...I now have beautiful car (beautiful paint, body, interior and now almost a completed powertrain, but I have about double into the car vs. what it is worth...but let me tell you..it is a head turner and I have the only one I know of the Greater Houston area. So..with all that in mind..I say "go for it!" It's only money and frustration vs. patience that you will need! Good luck!
