I HAVE AN 87 S-10 BLAZER WITH A 2.8. HOW HARD WOULD IT BE TO PUT A 4.3 IN THERE? WHAT EXZACTLY WOULD I HAVE TO SWAP OUT TO MAKE THE 4.3 WORK. I KNOW AS MUCH THAT A 4.3 WOULD NOT WORK WITH THE 2.8 TRANNY BUT WHAT ELSE WOULD I HAVE TO SWAP OUT? THANKS FOR THE FEED BACK.

ECM
Motor mounts
Yes, 4.3 w/ 4.3 tranny
4.3 Y pipe

oh yeah......... EASY... worst part is motor mounts... you have to drop the lower control arms to get to the nuts....... unless someone has a better way.... which i highly doubt

i dont know..i think i heard the transfer cases were the same...... i know the 700r4s are primarily the same from the end of the bellhousing back....... so im going to guess they are the same..... i know the 2wd trannies are the same except for the bell housing (length, output shaft) all that good stuff.... so yeah should work.
