If I were looking for an upgrade and had to stay V6 then I would look for a 4.3L Vortec from a truck or van. You can get carb intakes for fairly cheep and they make a bunch more power. They're also not very hard to find.
'79 Buick Regal 198ci to 231ci swap?

The 4.3L likely won't bolt to the BOP TH200.
Everything from the 3.8L should swap onto the 3.2L and vice-versa (except for pistons). I would put your current '79 heads on the 3.8 and depending on the mileage, the 3,8L might need a new cam/lifters anyway, so why not swap the heads, too.
Well at that point you may as well swap in the 700r4/4L60 with the 4.3, if you're doing a swap may as well go whole hog, no?
As hard as it might be, it might be easier to swap in a motor/trans out of a Diesel jeep cherokee than a blazer/S10 drive train, because I don't think those were ever sold in the EU.
Going whole hog is a little easier in the states than in the Netherlands.
It is a better trans, but there is an argument for keeping the TH200, as that motor shouldn't have enough torque to hurt that 200 if it is in good condition. Also, it is a lot lighter, has less rotating mass, and lower 1st and 2nd gears.
The worst part is that I never even intended on getting a TH200. I was doing a sight unseen deal on what I thought was a TH350, and I should have paid closer attention to the number of pan bolts...
