Sounds you are on the right track. thats basically what I have. right now i am running stock 317 heads.

 

and damn is it torquey. drives great.

 

are the times in your sig with that setup and if so what did you wiegh when you ran those numbers and how much were you spraying.

 

Those times were with the 6.0, the very mild 408 is running in the mid 13s n/a weighing around 5500 give or take a few hundred pounds.

 

if you've ever driven a 6.0L with a radix that's well dialed in, that's about how his drives. outstanding power at all rpm.

 

Is his cam bigger then the biggest one i listed? and what will i need for injectors

 

the cam he has that is going to go in there is bigger. for break in he put the same cam in that he had in the 6.0L which is much milder. it idles like a stock truck even if you set the idle to 500. there is no lope. the new cam should allow for power beyond 6000rpm.
