Oh yeah it's definately not a cake walk. The 2.8 ****** is a different bellhousing bolt pattern so it doesn't work. So I pulled a ****** from a 4.3 blazer 3 weekends ago. I am going to have that rebuilt to v8 specs. Lots of people use stock 4.3 ******'s behind v8s with no problems. I understand how much work/money it will be. That's why it's a slow project and only do what I can when I feel like it, hah. The motor going in will be pretty much stock. Hone the cylinders, new rings, new bearings, and stuff like that. It already has a different cam in it. The motor is going to be coming out of my dad's old 71 van. It still get's 2nd gear rubber with over 300K MILES on it and runs strong.
