97 Blazer Vin W and Vin V swap - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a 97 blazer with a bad motor. I picked up a 97 motor out of a S10 pickup. The problem is that mine is Vin W I think it is called SPI ? (I dont have my book in front of me) and the S 10 is Vin V TBI. Can I just swap the intake and put it in or are there any other differences. Plan is to put them side by side and swap what needs to be swaped?

Im not coming up with a "V" vin code for a 4.3? 96 & up '"W" & "X" will swap no problem. "Z" & "B" are TBI motors and heads are different. 95 and down "W" engines use a different style intakes that are all aluminum VS the plastic upper on the 96 & up and are speed density systems (no mass air flow sensor)

Taking a picture whould help
