276 stroker from 35 years of parts

[Bored&Stroked]

If that block sealer is a water-glass, ceramic type sealer - then maybe use it. If not, don't use it - just order the Moroso stuff and put it in at a later date. Some of the block sealer products gum up radiators and make a mess of things. I've never used the KW stuff - so I'm always a bit wary!

Best of luck tomorrow - it will be like Christmas for sure! There is nothing more fun than starting a new engine!

Take care,
