i have seen a lots of posts on this forum and the internet in general of people getting "advice" on this sort of stuff. it usually leads to people getting in over their head and/or giving up. usually people giving the advice have shops, tools, know how, extra help etc etc. and sometimes aren't realistic with who's on the receiving end of the so called advice. i have bought lots of projects from folks over the years that just didn't have a plan or read it on the internet or got bad advice and usually the simplest solution was just to fix what they started with. 10K is a big budget but you'll go through that in a hurry if you dont have a plan and stick with it especially with this post-covid market insanity we sre currently living in. Remember, more power means transmission work, diff work, etc etc....
sorry about the the "good grief" comment but there is literally an active post with 13 or 14 pages on this sub-board with someone with a very similar dilemma.
PS: the worst thing about this hobby is having a vehicle that doesn't move. having had projects down for weeks/month/years over the last 20 years i've come to realise that splitting a project up into smaller sections where you can still drive it is much more enjoyable and you don't lose interest. some will argue, why fix head gaskets on an engine you'll eventually pull. waste of time, etc. like i said for a few hundred dollars you can fix it enough so when you need an escape you can go drive it. while you are driving it you can put your headers on and get the exhaust done, upgrade the fuel system, maybe start PROM tuning. all while you build up a crate engine in your garage/shed/basement
