wtf!!! is wrong with my 408 iron block
cam is too small for one. you need a different intake. what size headers you running? and i havent seen too many autos over the 500 mark with a 408. james day is one of the only ones ive seen(535rwhp) good luck fixing it, get that thing to the track and see what it does. dont rely too much on dyno numbers
About every stage 2 head I have seen on our dyno made stage 2 power, even on the bigger engines.
You have a 346 cubic inch combination and your making 346 cubic inch power.
You need to buy a combination from someone, killer heads, Fast 90/90 and bigger cam. Just my $.02
