Did anybody else notice that MMR now produces a MMR800 shortblock for the 4.6? Used to only be 600 and 900...just thought that was interesting!

Nope but thanks for the info!

 

I kinda doubt that theyre is actually much difference, i think the webiste is kinda vague in many respects, the type of the matierials used from option to option to dont seem to warrant the claimed increases and decreases, my bet... the 600 in a real world app will probly hold just as much as the 900, but id love to see some research and facts on this
