I paid $350 for a complete 1999 5.9 Magnum from a Dakota R/T, in running condition. It has 80,000 miles, no sign of blowby, some coking on the inside, a full quantity of slippery dark oil in the pan, the full serpentine setup less A/C compressor and the magnum exhaust manifolds. I bought an airgap style polished intake used for $100. The rest of the package will come from the original LA 360 in the car and some new gaskets. That's my definition of on a budget. Hopefully it will be the equivolant of a 300 hp magnum crate when it's complete. Why pay for machining when it's still good?
