I don't know man, as rebuilding and machine work plus trying to recon the OE heads seems like a pretty big expense right there.
2.5-3k miles is quite a bit, but I will tell you this.
I paid 500 delivered to my house from a private seller for a Magnum with 92k on it and on the inside it looked like 20k or even less.
Barely any markings on the bearings and very obvious cross hatching in the cylinder bores.
The Magnums have a very low wear amount than V8's used to have.
Put it back together adding a brand new set of EQ heads with 1.96 valves, Hughes springs and retainers, an Oregon cam grinders roller regrind and grand total was right around 2k for a 400hp/420tq screamer put together as an LA motor.
Can you come close to that with heads reworking and a motor rebuild?
My block came out of a front end wrecked truck, so you might consider looking for something like that instead of a running vehicle that's going to cost you more and have to rebuild it anyway.
Just a thought.
