I stand corrected. Anyhow, IMHO, I would opt to look for a Windsor engine because there are more aftermarket parts available.
You'll spend less money to make more power with a windsor than you would a "modified" engine. That's just me though.

The only way I know to tell them apart is if you take the engine apart. The 400m has a longer stroke(4 inches) and the 351m has a 3.50 stroke. The pistons in the 400 also have a higher compression height.
Unless somebody on here can decipher the rest of the codes.......
