I'm planning on replacing the coolant in my 96 LT-4. On my '73 I pull the drain plugs on the block. My question is do the C-4 LT engines have block drains? If so, any pitfalls to pulling them. In the old days I used to do the prestone flush 'n fill. However the first time I pulled block plugs on the '73, I was ASTONISHED how much coolant stayed in the block. So I figured that might be the way to go. I'm still not comfortable lifting this car, so would probably have the dealer do it. (4 post lift still a year or so away)
