Ported FAST or 4.10's
Having cam (.236/.238 .601/.605 LSA12) springs, rods, UD pulley & ported fast being professionally installed in 2 weeks.
I started thinking that maybe I should go for the 4.10's instead of the ported FAST, they are within $200 in price installed.
I am already putting 390 down (see sig)
Which would benefit the most at track or just daily driving?

I have 4.10s in my MN6 '05 coupe and I love them. I now have a 6th gear that is usable on the highway and from 45mph up; I used to have to be in 5th gear at 45mph to keep from lugging the engine.
I lost ~2.5 mpg but cruising at 75mph in 6th gear is still a respectable 28.5-29 mpg with the engine turning at 1950 rpm.
With all of your other mods, I would opt for the gears and get the ported FAST on your next round of mods.
JMHO but HTH...good luck.

410's are awesome, you will absolutely love them, they make a HUGE difference!! I enjoyed the 410's sotp almost as much as the supercharger sotp when I had them installed.

Go for the gears. You will NOT be disappointed. Best mod out there for Vettes.
Best way I can describe it is that if feels like your car lost 500 lbs - it reacts so much quicker to every throttle imput.

4.10's for sure huge Sotp feel. I installed the fast 90 one month ago, also an amazing mod, you will feel the difference, but not like the 4.10's, read my profile on mods..The fast 90 should be a definite mod to compliment the cam regardless which mod you go with.
