Hello all, I am new to series Land Rovers and am looking to purchase a series III with a 2.25 that is toast. I will need to get ahold of a short block, long block or bare block and do a rebuild. I have some mechanical experience, taking out transmissions, engines, fixing clutches, brakes, etc on Jeeps, and minor work on other cars I've owned. I've never been into an engine or transmission. I usually try to do my own work with shop manuals and feel I could rebuild a series engine, with a good manual, as I've heard they are fairly simple and straightforward.
But, I wanted to run it by the experts

here, as I know many of you have done overhauls and see what you thought the difficulty level was. Parts seem readily available and not all that expensive for the innards, complete rebuilds I've seen for like 4500, so I'll definately be going with a rebuild.
Also, what have you found the best manual to be for engine overhauling and/or complete vehicle service?
Anyone done an engine conversion, maybe with a 258, V-6 from a Jeep? (it's what I'm familiar with, sorry!)
Thanks for any help, it is appreciated!!
