New motor 83 k10

I already dropped it in. I’ve never driven a lifted 4x4 with so much acceleration. It slings mud like it’s nothing but I drive it on the street too. Took it to grab some take out food the other day and man it just goes lol I’m estimating around 500 horse. Had a mild built vortec in the truck prior to this

The tbi are like 185 hp. The swirl port heads and dish pistons really bring em down a ton. A set of vortec heads and a cheap cam/lifter set would really wake that motor up. LS are great too. I’ve got a 2013 Silverado with a cammed 5.3 and that thing rips lol I also have another one with a 6.0. Cost wise I’d just do top end on the tbi motor. I’m running a built 700r4. A 30 spline. Newer 90s style. My transmission guy said I’d blow a 27 spline to pieces. I had the trans built for this motor. They’re both fresh.

What do you figure a LS swap will cost you? About $1500?
