Default blazer swap thoughts t67 vs sbc

So as many of you know I have a 93 s10 blazer that has been a thorn in my side for a while now but the whole camaro thing got me thinking and bad things happen when that happens lol. The 4.3 that is in it is tired and old and at the moment wont run and so this led me to a v8 swap site but the same complaint always came up... tight space and crappy access to the important parts. This I saw a thread that had someone asking about a l67 in the blazer and it got shot down by all the v8 lovers but it got me thinking and digging. If I will have the intake off the camaro then that would make for a killer turbo start point for the blazer. then think about the 4l60e that came in the v6 birds could be swapped to a 4x4 trans at a trans shop where it would be beefed up to handle a turbo 6 power plant so this would leave an issue of the oil pan and the mounts. the v6 fbody mounts would get me into the ball park then mock up an adapter plate out of thick gauge steel and the oil pan would prolly need minimal trimming to clear the front diff.

here is where the T67 starts to shine according to a site online the dry weight of the l36 is 375 lbs which is 50 lbs less then the 4.3 stock let alone the common sbc swap that weighs in at a whopping 600 lbs so roughly that is 225 lbs off the nose with the l36/l67 in there then if you add a turbo and an FMIC you are close to the stock weight of the stock motor.

so let say for kicks and giggles you run a l26 bottom and blended and smoothed heads with a xp or turbo cam with a t72 turbo and 80# injectors and e85 you should have a 400 hp motor in a truck that would would prolly net a 13 in the 1/4 mile and yet still be able to do some light to medium wheeling or light hauling like jet skis.

I know the sbc swap is a proven swap but lets be honest why add weight to add power. After seeing Kevin'* results it has got me thinking. Also this has throwbacks to the cyclone and typhoon but only modernized.

What are thoughts on this and I have also considered a Lsx swap but you are still and 100-150+ lbs over stock and I have heard to get them to fit the fire wall needs some massaging for it to work in the 4x4 configuration.
