i have a 73 sbc 400 from a caprice that has 3 freeze plugs. i have always been told that 400s had 2. is this a different sized engine or just something different? thanks
The 2 freeze plug block is the preferred block (supposed to be stronger...?) The 400 w/3 freeze plugs was more common... Both come as 400`s...
