Hello to everyone here, you guys have alot of good information. I want to convert to a 5.3/4l60 for my 72 2wd blazer, I have the engine and tranny available to me for $600 from my uncle, he was going to put it on his 75 shorty but his friend talked him out of it, told him it was going to be to complicated to do the conversion. The bad thing is that I don't know how to do any of the things you guys talk about here, I change the oil and pluggs on my cars thats about it. The engine-tranny is out of a 2005 silverado, can I use this one?
