I think you are headed down the wrong path.

Even the s10 swaps I don't care for, but that's just me, well, and some others too I am sure.

Please don't ruin a good 3800, if it won't fit in your garage you either have the wrong garage or the wrong truck.
My 52 3800 could use some company if you decide you have the wrong truck....

What ever you do, be sure you are doing it for the right reasons, and do it well.

Good luck,
Grigg
