I'm going to take my 2f to a local machine shop to get the work I need done for the rebuild, but since this is my first time rebuilding an engine I wanted to get you guys input on what to have done while it is there.

Here is a list of what I plan to do, if there is anything else I should have done please let me know:

Bored .030"
Decked .012"
Crank grind
Head milled.030"
Head rebuilt
new camshaft

like what about port polishing and resizing the rods???

Suggestions welcome
Thanks

Have them check everything out before you jump into resizing the cylinders. I took my engine to a shop that is used to working on Chevys and Fords and he was amazed at how little wear there was on a 27 year old engine. I didn't resize, just cleaned everything up, honed the cylinders, ground the crankshaft and replaced the rings. Everything is working great now.
 
Yeah, that is a good point, the engine I have supposedly one had 54,000 miles on it, but the ring wear shot.........maybe the wear isn't to bad either, and I am sure not boring it would save some money and that is always a good thing:)

Thanks for the info guys.
 
What Pin Head said. And have them at least check the align bore of the mains. If it's not true, have them align bore the block.

Milling the head 0.030 really isn't going to give you much extra "umph". I'd suggest taking off just enough to be sure it's flat and not go any deeper.

Enjoy your new motor!

Probably won't need an overbore; don't spend on new pistons unless they need toi be replaced. The cam and lifters should be replaced, the crank will likely be okay as well. forget the porting. just back cut the valves 30 degrees. mill only to insure flatness. the upgrade to a electronic distibutor and a well tuned carb will get you the power you want, not the extra machine work.
 
And a new OEM water pump.

Learned this the hard way. Brand new engine rebuild, driving down the hiway at night with no doors and the usual minimal dash light. Overheated the engine and had coolant running down the side of the truck before I knew what was going on. Had to pull the whole thing apart and start over. Ouch.
 
Should be no need to bore unless something dramatic happened in the engines previous life. Check ring grooves. either mill the head enough to true it, or take off .080-but don't do the latter without making sure there's enough room for valve clearance. I've never had that issue with a 2f, but it'd be dumb not to check. Balance rotating bits. Having them assemble the sort block is cool if they'll warrant it, and you don't want to try it yourself. It's not hard with a factory service manual if you have basic skills ring compressor/file and some feeler guages. Installing cam bearings sucks, pass on that.
 
Thanks for the input Chef, The problem for me is finding a decent machine shop around here, or one that has a clue what a landcruiser is......................
 
Anyone who understands a chevy 298 straight 6 should have no problems with an f/2f. timing gear oiler and some other small subtleties, but pretty similar...
 
If you go to a machinist that is not familiar with the 2F make sure he installs the head gasket correctly. If he uses an aftermarket gasket it is very easy to install it flipped covering the oil port to the head. I found this out the hard way. The guy I went to had done hundreds of engines and still made this mistake.
 
Well now I am considering just taking my engine to David Dearborn/urbanlandcruisers, they offer a good warranty and have done a lot of cruiser engines. I had intended to reassemble the engine myself, but the more I think about it with my inexperience with engines if I screw it up I have no one to turn but myself. So i think I am just gonna pay a little more for the piece of mind.......
 
Roger that, and he's so close to you why not? PS no affiliation.
 
Yeah, that is what it got to thinking, Why not???.........I originaly was going to try to go as cheap as possible being a college student and all, but I think a little more up front now would be worth it in the long run
 
Building an engine by yourself for the first time can be a humbling and aggrevating experience, which is why I suggested having the machine shop assemble the long block. It would be a good experience if you found someone who wouldn't mind if you participated or watched while they do it. If the shop has never done one before, take a copy of the OEM service manual with you. They are very much like the old GM 235, so old timers will familiar with them.
