[347]

i am trying to eliminate a flat spot under 3000rpm
i have 50 idle jets
i had 150 mains,175 air correctors,f11 emulsion tubes
i changed to 145 mains and left the others which slightly decreased the flat spot
tonight i changed the air correctors to 200's which made it better again but still not perfect
do i need to try something else or does the overlap of my cam cause this rough patch?
cam specs......solid flat 560lift 248@.050 110 lobes 294adv

i have 44mm idf webers,engine in a 347

thanks
