440: Rebuild, Replace, or Sell

Well $3500 isn't that far off from $4000!
I bought an old drag car with a 600 HP and I dyno'ed it.
Paid $9000, kept the motor and trans and resold the chassis for $5000.
It sits in my 66 coronet now, I couldn't built a motor for that and I ended up with a built 727 too!
