Yeah you can probably plum that all in within a few hours and be calling the junkyard for another motor within another hour..lol..

I'm pretty sure the 1st (aka worst) engine would be a sacrificial lamb. Just for fun (see what it will take) engine number 2 would have new rings gapped for the sauce and use the knowledge from engine number 1 to survive at least 2 hours.
