Brand new member here! I have the opportunity to pick up a L67 engine with super charger and wiring harness included for dirt cheap. The only problem is that the engine has 340K miles on it. Even though it is really cheap I don't know if it is worth getting if I'll have to end up rebuilding everything. I was planning on doing the upper end no matter what but really would rather stay way from rebuilding the lower end.
Ideally I'd like to go with some light performance mods to start with such as a 3.5" pulley, thermostat, cold air intake, mild cam, PCM, etc. Would a lower end with 340K miles be able to withstand any of this? Any opinions on from you guys on this would be much appreciated.
That engine more than likely at the end of it's useful life. If you don't want to do a rebuild on it, don't bother with that engine. And with any mods like you would like to do it wouldn't last a week.
Edit: what is your idea of cheap? And oh yeah, welcome!

Never rebuild or buy a rebuilt 3800. I wouldn't see a problem with running it. If it does fail down the road its really not that hard to change out the long block. Once you do the initial swap all the hard work is done.
I personally don't think I would go through the trouble doing a swap with a 340K engine. But for 250, the components would be worth it alone. What is in the car now?
I typically buy engines with under 70K miles on them and always do a cylinder leakdown test before installation. If the engine undergoes long term storage in the shop for a while and many do, we remove the plugs and fog all of the cylinders with a generous shot of oil. then a rotation or two so the rings and cylinders stay free of rust.

"Thanks guys! I would be able to get it for $250. That is with the wiring harness, supercharger and other engine bolt on components such as water pump, etc." You can go to a" U-Pull" yard and get one with a Warrantee for $250 ! (an extra $50 and They Pull it). the harness, you'll have to "Build" a Harness anyway ! That NOT a good deal.
