Well mine has been in the garage since November, so believe me i know. I can only say one thing about doing it right the first time...
My roommate has an 86 K5 Blazer, he bought it for 500 bucks and it had major engine issues. He tinkered around for a few weeks on it and then decided to just get an all new engine slapped in. So he ordered a crate motor while he was waiting for that to come in, his tranny went out so he ordered a new 700r4 after he got all that together it was running okay. had some EGR issues, fixed them then he sold his DD so his blazer was his prime mover. well, his Transfer case went out. Waited 2 weeks for a new one. (all of this work he had shops do for him). Now he gets the transfer case in and it's good, but he's got a 6" lift and some rims/tires he bought off of lagen. Well he was in such a rush to get it done so he could take it to tahoe for a week. there were tons of problems with the lift, and after he sorted some of that out, he slapped on the rims/tires, and on his way home, his front right tire started to wobble really bad. he had the wrong lug nuts from kragen which he knew and he didn't get the nuts all the way down and it sheered off a couple of studs. he was stuck. and had to get it towed back a 4th time. i could add in all the rest, but you get the picture.
It's better to have it in the garage an extra week or month than to find out you overlooked something later on and have to spend even more time/money repairing it and doing it righ.
that's my 2 copper pieces
