420 Windsor
Has anyone here built the 351 W AND stroked it to the 420 would like to know what you think.

I am working on a 4.155" bore x 4.000" stroke windsor right now...

I personally do not like a over square (bore smaller then stroke) engine for best performance, so i bought a dart block for the build...

What is your application and target horse power???? Are you planning on running a stock block???

When using stock blocks, I personally like the 408 for street use, kind of gives the best of both worlds, anything above 408 I use for race only.
