Re: having engine remanufactured
Brad, Stephen, and Dick are all very correct....having done 2 258's this past year I can only add the following...
1. Make sure you use a machinest that knows what he is doing...i.e., he measures before bores...and if he says "thats looks close enough'...don't use him. In my case, I took the pistons to him and he bored each cyl to match the respective piston.
2. Spend the bucks to have it balanced. When doing the flywheel, have the clutch done with it. Trust me, you will be glad later.
3. Plasti gauge the rods and mains. If they are close to the limit...around .0035 I believe, have the crank turned. Otherwise, you will start having low oil pressure problems sooner than you want.
4. If you want to rock crawl then don't go with a radical cam...you will never be able to get a decent idle.
5. As stated above, CLEANLINESS. Any dirt left in the engine ends up on the rods and mains.
6. Take your time....unless you like doing it twice.
7. DO NOT let them knurl the valve guides....it will only last about 10K miles..if they are out of spec, then spend the bucks for new valve guids...and valves if they too are out...otherwise, we will start getting questions from you as to why you are getting oil in your air cleaner.
8. Prime the oil system prior to startup.
9. Make sure you double check all torques.
And most important...have a last look over before you start it....don't be in a rush to crank it up.
