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.
