dyno flo is advertising brodix, dart and merlin z aluminum b
 

whats the differences in them and pros and cons of each.

I suggest before you do them you might try Tim Allen at Allen Motorsports in Dallas Texas. I think his ebay is 1350 hp not sure I will check if you are interested.

Phone # 214-391-7562

That is where I buy my Dart Blocks and the other stuff you named at some very good pricing but I will attest to his honesty and his customer service. Highly recommended by me.
