Need some of y'all to review my logic and provide some advice.

Alright well here is where I'm at. Found a lq4 out of an '04 van. Has everything except for a/c comp (already have a sanden 508 v-belt comp on truck now). 130K miles for $1000. Also have a line on a 4l80e with 80K miles for $500. Trying to buy both this week. Here is where I need help:

What do I have to look for when going to look at these engines. COMPLETELY new to ls engines so assume my complete ignorance.

Also help me make sure I'm not forgetting anything major that I need to mod:

-need tubular engine stands
-long tube headers
-f body oil pan
-radiator hose adapters for stock 4 core
-elec speedo of some type
-move trans cross member
-possibly use rear mount tank, but possibly use stock fuel tank for now

Please weigh in on plan to date and feel free to give suggestions on fuel tank, headers, mounts, a/c bracket for 508, and radiator hose
