I've been reading a lot of threads on these forums for a while now.
Has been very interesting to see the hp/tq gains from various applications
and the perspectives in relation to aspirated and F/I potentials. Check
out this link from Comp Cams website. I'm pretty convinced per all
I've read that the right naturally aspirated setup offers a ton in hp/tq
gains. These Hemi's are pretty amazing. A streetable 550-570+ hp from
our 6.1's seems very possible. (like seen on HHP's stage2 website link)

For those considering power adders..I'd be careful with your selections
and whether F/I is really necessary..unless of course your pushing
for the 800+hp territory like Bill :) Then you'd better budget for the
whole drive train.

ATI F1 or Novi 2200 should do it for you, along with a forged bottom end anyway. :D

Forged Bottom End, Custom Twin Turbo, 18-22psi.... Already Negotiating with shop >:)

Fitment of twins is going to be tight as hell. Best of luck!
