if you want to break 400 do the UDP ,or consider a electric water pump.or index the spark plugs,or use all synthetic fliuds.

what? Like regapping or plugs or using a synthetic oil will help hp??? Or are you being a smartass cause its a hp?

temperature of the day wouldn't matter at all, dyno shops use SAE correction factors to make sure variances in power are minimal if not zero. Unless its a pride thing where you just want to say 400 horses then you can look at the uncorrected power readings.

To me mods that you can actually feel a difference (Long tubes, cam, ls6 int, ect) are worth it. Stuff like ported tb's, pulleys, e. water pump are nice to have but id rather save the money and spend it on something better. On my previous cars I did all the little mods and had regrets later on when I felt no difference.

I just installed my underdrive pulley and I love it, you can definitely tell the car revs up quicker just driving, WOT throttle felt the same as before of course though

all the little things do add up. my only side effect was a slight shudder feedback to the steering wheel when turning it when the vehicle was completely stopped - something you would basically never do. it's a good mod

800 rpm idle got mine good to go with everthing on
lights,a\c,wipers,rear defrost, etc.

I believe it is a matter of taking off a belt, one bolt and possibly using a puller. You could do that while the kids are rotating for bath time.
