Most likely any S52 or 6cyl you find will require a rebuild as well. Low miles examples will demand a premium and lower costs ones will be worn out. That said you should budget 1.5-2K just for the rebuild alone, unless you just want to toss in an unknown engine. I did that and didn't touch the rotating assembly and now I'm pissed at myself I didn't. Re can squeeze a small amount from a tune/fresh rebuild on the M44. There are some interesting intake solutions on line that people are starting to sell (itbs, etc) to gain a larger percentage of power. Realistically find a budget and you can start down a path there. |
