400 sbc again or LS1 swap...what to do

Ok so after blowing my 400 sbc 4 weeks ago we finally got it pulled and torn down to see the damage...spun bearings, broken ring and a bunch of stopped up water jackets. It's the one thing we didn't rebuild on the truck when doing the resto cuz it was already running good.

I've found a rebuilt short block for $600 and heads with fresh valve job for another $200. I also came across an LT1 with tranny, computer and harness for $700 and it has 78,000 miles on it.

Here are my questions...what has to be done to put the LT1 in and what's your opinion on the best way to go...back to the 400 or do the LT1?

I'm trying to keep the cost as low as possible...
