Due to a miraculous occurance that has left me in possesion of a mountain motor for my IROC I am getting ready to pull out my mild 355 and get a little nuts. Going in is a Bowtie block with 400CI, AFR 210 heads and 500 N/A hp + the bottle. How much power loss do you guys think I would have to endure if I used the Hooker 2055s and hooked them up to my brand new Hooker cat back instead of buying 2210s and putting on a 4" mufflex? Will the 2055s bolt to the AFRs? I am sure it will cost some HP but not sure its going to matter to me since there will be more than enough to start with. Any input appreciated.

im unsure if theyll bolt up or not, but they should. Maybe someone else can chime in.

As for power loss.... way more than I want to think about.

hehe, your 500hp just turned into about 400hp.
