Having owned an airgap. It takes 30 minutes of driving before the intake gets warm enough to drive without off idle engine hesitation. When it comes to carbs, cool fuel is not a good thing, as the fuel tends to change from vapor back to fluid then puddles up. Anything less than 50F or even 60F makes for a long warm up period. I removed that airgap as soon as a could and went back to the regular rpm. I hope you have better results with the airgap than I did.

The carb is too small. Get a 750. Install the vortec heads with a .015" shim head gasket to get the cr up.
Nice nitrous cam that will run good N/A too. Crane F280-2 280-288 244-252 .518-.536 112LSA.
10" high stall. The Air Gap manifold is just right.
You can run up to 180hp shot on good pump gas. ( i"ve hit it harder)
200+ use 110+octane unleaded race gas. The under hood fuel cell is a great idea. I use it too.
The bigger shots really favour a mechanical lifter cam like the crane F280-2 as the motor will rpm.
These are very street easy mechanical lifter cams .
Get a ignition retard box and a RPM window switch to control nitrous engagement/launch rpm on launch.
When combined with the right torque converter stal speed this avoids over-torqing the motor on launch.
(bent connecting rods). You don't want to hit a 350 with 350hp shot at low rpm.
The rpm window switch wired to the WOT switch allows a hard hit right off the line.
@or near converter flash stall speed or slight time delay, as required.
The nitrous would come on a say 4000 rpm (converter stall speed)
This is how you hit a 350 hard with a big shot and go fast.

born and raised..... currently serving in the airborne infantry on ft bragg NC tho... i grad greece olympia in 04
i bet that you didnt see that one coming lol

454c10- i actually already have all the parts... i went with the air gap for the the cooler intake temp and also the longer runners. with the longer runners the velocity is increased and thats the main "feature" of the vortec heads. Thats also the reason for the poly carb spacer...
as for the extra fuel cell, i was thinking something very similar to doing that. but i was curious just a electric fuel pump in there? and it only turns on when you arm the system?

when i got it... it ran a 13.8....id like mid- high 12's...later today im putting the new top end on....
gary on a side note, when was the last time you had a garbage plate from nicks?

If you haven't purchased the air gap already, then don't. Get a regular RPM intake instead, as it will have much better street manors, especially in the cooler months.
Same for the carb. Get a holley 3310 750 instead if you haven't purchased the 670 yet.
Plus the 3310 and the regular rpm will be much cheaper.
100 shot should not be a problem. Retard the timing a few degrees and make sure the n02 system has a separate fuel pump. Setup the activation switch for full throttle.
On my n02 setup, I used a 1 gallon fuel cell mounted in front of the radiator and ran racing fuel for the n02 fuel enrichment. Just an idea.
Your 383 should make 400hp and close to 500 ftlbs of torque.

|vinniekq2||like OB said,the ring end gap needs to be increased. The 100 hp NO2 shot will increase your torque by closer to 200 pounds.If you have 450 pounds of torque now, then think what 650 pounds of torque will do?|
