Difficulty of Rebuilding?
I've never rebuilt a motor before. My current motor has 130k on it and is on its last leg. I want to buy a junkyard 350 or 400 over the winter and rebuild it as time/money allows. How hard is it to actually rebuild a motor? If I buy a book on it will I be ok?

Not hard if you measure everything, twice, and be sure of your clearances. It is expensive, however. Machine work costs an arm and a leg now a days, and you need to make sure to take the block to a GOOD machine shop, not Bob's cut rate butcher shop.

word of mouth really....
I learned of my choice machine shop just from a mechanic at work, he's a high quality guy so i assumed he'd only accept a high quality place to do his machining, and i was right.
of course one thing to think of....
a machined junk yard block can be just a little less expensive than a brand new gm or aftermarket block. personally i always just shell out the money for a brand new block, at least that way you know exactly what you have...

Assuming a 350 (because you don't want to spend any money on a new 305 block) - starting at about $1200, go to around $2000 for factory new shortblocks.
Actually, you don't really want to rebuild your 305, either. $'s/hp, it really isn't worth it. Actually, $'s/anything, it isn't worth it except for the experience. Even then, it makes more sense to find a builder 350 engine and re-do it.

I was considering buying a shorblock as then I wouldn't have to mess around with the bottom end. I was a bit intimidated by the crank/bearings. Do you know of any good places that sell rebuilt shortblocks?

The L98 shortblock doesn't sound too bad. I don't think I need a 4 bolt main seeing as I will only be putting out ~400hp. From what I've seen people have been getting decent power out of the L98's, would it matter any that I have carb and the L98 was a TPI motor?

Personally, I've never heard a story of someone F*cking up a 2 bolt main, If anyone has, let me know.
