drop in? I really doubt it.

Putting a stock LS motor in a C3 has fitment issues, with the paxton on the front, I think your problems would be multiplied.... as the saying goes, "with time and money anything is possible"

still, that's a decent price for what you're getting - that said, I've yet to see grandma buy that stuff, so 40k miles could be 40k very hard, racing miles.

Lots of LS C3s. I would not spend too much on one with a centrifugal supercharger, might be an expensive experiment. I'm also guessing interference issues with the crossmember, A arms maybe, radiator clearance. I I've seen a SBC C3 with a centrifugal SC, but I'm not sure if it was a custom mount.
There are several low profile valley mounted superchargers (Magnacharger) that would be an easier fit in a C3 LS1.

what r u thinking its better :

go with 4 bolt 350 engine stroke to 383 ( Forged Stroker Kit ) 10.5 c\r , zz4 cam, 4150 carb , with tko 500

or used LS 2/3 engine with m\t

The only fitment issues with a LS are the heater hose connections on the water pump and maybe the trans cross member - depending on trans used. Both are easily fixed. The LS would however, need other systems changed - fuel delivery, electrical, gauges, ect. It would be more involved than just a small block swap. That said; I like the LS. I am over having a big cam small block, and like the style of the C3 with modern power. The double overdrive six speed, fuel economy, and smooth power fit the way I drive now.

Yes that ls1 will fit in your C3, but you would have to replumb the turbo and deal with the LS swap fitment issues which can be found in many build threads here on the forum. Doing a Gen 1 replacement motor would be the simplest swap, but that LS1 turbo swap would be nice as well with a little work and fabrication.
I'm running a ls2 (402) rebuilt stroker motor in my car and love it, the sound is awesome and the performance is fantastic.

Vortec is a belt-driven blower.... there are a finite number of places it can go; and on a C3, there are limited places things can be put... I won't say it can't be done (because some bastard will come along and show me with pictures they did it) but it would be a lot of work... a LS1 motor, without the centrifugal blower would fit relatively easily

Super, Sorry youre right, I was in a hurry when i posted and thought what I seen was a turbo, not a super charger. However, I think I could run one on my setup on the passenger side since I'm not running AC. I would have to build a one off bracket for it, but it would not fit under a stock hood.

Sorry for not looking at all the details, I need to slow down and look a little closer before posting.

To get it on the road ASAP, SBC all the way.
For good milage, drivability, reliability, LSx definitely. One aspect on reliability is that you'll update your fuel system, electrical, many upgrade AC, power steering, cooling etc too. So you get the reliability of the engine itself as well as all the peripheral stuff. The SBC may itself be reliable, but using with a mix of decades old parts can still leave you stranded.

my LS fit right in

and my Procharged SBC no fitment issues other than hood clearance
