Default Engine Swap Ideas?

What engine should I put into my 1996 Chevy Blazer instead of the stock 4.3 Vortec? Iím not sure if I wanna go with a SBC or something else. And if I were to make a performance build, how much power could I put through the transmission without breaking it? I think the transmission is a NV3500, but not sure.. Can anyone help?

Only truly nice swap is a LS Chevy motor complete with factory fuel injection, but you will want to do an automatic trans and will need a donor vehicle for computer/wiring/accessories like a pre-2006 Silverado or Avalanche and will obviously need custom programming. These engine swaps are not cheap, nor are they for the faint of heart or the inexperienced. Getting the second generation vehicle systems to be compatible with the PCM used is a concern. Lots of S10/Blazer swaps get started and never finished. Don't be one of them. there is a member that did one and posted in the builds - ou should read that. His started as a manual trans 2WD.

Are you sure that 200 hp isn't good enough?

Iíd like to get more power because eventually Iíll be using it as a mud toy and want to work on all of it to begin with.. and I was wrong, the transmission is a 4L60E with Overdrive... Iíve thought about getting a Small Block 350 but donít know what all Iíll need or whether or not I wanna do some performance upgrades to my current 4.3 V6

I've been researching the vortec 350 swaps, those seem like they'd be the easiest

I thought about that for my build but decided against it. I would no longer be able to close the hood.
