    time to upgrade the 6.0 one last time

    i got a 99 6.0 with iron heads.. think i am gonna swap to a 243/799 head from what ive read on here. what size cam do you guys recomend going to?? i plan on buying a stall converter and did the 4l80e swap already. also heard alot about nnbs/tbss intake upgrade. what do you guys think i should run top end to give it some more get up and go. and what converter stall to match. i would like to hit 450 maybe 500 hp on the motor. and have a agressive idle.

    i got a good deal on a comp 550 ish lift cam and a monster trans converter but it just doesnt cut it. glad i dont have much invested!!

    let me know what you guys thing and any other things i should so as welll!

    As far as stock casting heads those have good flow. The nnbs intake swap is great with a 90 mm TB. Cam and stall choice go hand in hand. A good combo might be 231/236 with healthy lift and a 3600ish triple disk stall. You will get some big results.

    The NNBS intakes come stock on NNBS's. You can get them brand new from Rock Auto for $99+shipping. Cam in the low 230s.
