Default Head cam intake 98 z28 looking for educated guesses

Hi everybody, I'm almost done stocking up parts for my h/c/i swap on my 98z and was curious what everyone thought it will/should put down so here is the run down
Sbe 160k
228/232 cam
Prc stage 2.5 243s 64cc
Fast 92
.040 head gasket
1 3/4 longtubes
Td dumped at axle
Gtp injectors
Racetronixs pump

Going threw a six speed and 10 bolt (4:10) will be dyno tuned locally maybe in June

Was definitely looking for people who have ran a setup close to this. Its a fairly "simple" build

I think anything over 450 is unlikely but this is my first v8 so we will see

Well it's been a while but the build is finally happening a couple of changes though, car will now be an auto with a 3500 stall and 3:42s also I decided to refresh the bottom end. block is at the machine shop now. If it goes good should have #s in a month or so. had some issues with getting a rebuild kit for the automatic in a timely manner so thats gonna drag this out a little longer.

Alright, the build is still alive. I've had a few more delays I bought a house and had a baby + working out of town. The car is almost completely back together I'm sending my pcm to lsx power tuning Monday and all I'll need to do is wire up the auto shifter and fire her up and see what I messed up.

[BUMP] car is running pretty good. I've been ironing out the little kinks and she is hitting the dyno Wed the 24th. It will be on a mustang dyno here in Tucson and Evan Smith of ES TUNED will be doing the tuning.

That torque is peaking way to soon. What's up with that?

I'm no expert so just a guess but possibly torque spike due to unlocked converter on the dyno.
Once it evened out I wound think around 360 -370 tq @ around 55 - 5800 rpms

Makes sense. I've seen stalled autos dyno all over the place. I know one guy with just a basic HCI make like 480 hp and 380 tq lol. His car runs good but its more like an honest 440-450 in reality
