Need advice: LS ENGINE SWAP

[desertdogg]

Im sorry about all the questions, but how hard is it to remove existing engine ? then install the new one ?...Reason I ask is I had a local garage say just to remove the existing engine and just seat and secure the engine would be $900 bucks. Im not sure if this is expensive or not but I was thinking I could at least remove the existing sbc 350 and TH350 tranny without too much trouble ? once its out I wanted to clean up the firewall and front end a little then paint...Once it was out I would probably be tempted to install the engine and tranny as a whole ? how hard is this I know the hood would have to be removed, would I have to remove the front fenderst and panels too and the radiator ?
