Well after reading a thread in tech about a guy who was looking at a potentially ::real:: boss block, i started wondering what exactly ARE the differences between the two.

from what i understand:

1) 4-bolt main
2) screw in freeze plugs
3) high rise intake

thinking:

4) assuming a hi-po cam?
5) stroke difference?

my question is:

what exactly are the SPECS. for the boss block? ie. intake runner size, cam duration and lift, compression ratio...etc...and how they stack up to the standard 302 block.

I was just thinking it would be kinda fun to add some things to my block....
