I know you guys have probaly heard this a lot but i couldnt find anything with the similar setup as mine. Im gonna be running a 347 with a 645 lift solid cam 300 duration afr 205 cylindar heads with larger nitrous exhaust ports 1 3/4 headers about 10 1/2 to 1 compression and i was thinking about running 3 inch h pipe with 3 inch flowmaster 1 chambers to dumps is 3 inch too big for this setup possibly? Im pretty sure this setup is gonna make around 500hp mabye more but im not sure if 3 inch will be too much? thank you for your time.
