Well this winter I plan on building my 305 5.0L TPI GTA. Some of you might think why not just put a new motor in there but my car only has 50k miles. So what im asking is what should I add or look into when i upgrade the car on suggestions or things im missing to make sure this process is a safe fly. Also let me know how you guys feel on the brand or what brands i should look into. Thanks

-Magnaflow 3'' Stainless steel dual rear exit catback-3.5''tips
-Pace Setter headers-1-5/8'' primary tubes, 3''collecter, mid-tube, painted finish
-Edlebrock Performer Intake Manifold, Polish finish, 4-bbl spread bore carb flange, Idle 5500rpm
-Sealed Power piston rings, oversize 0.030'', top ring 5/64'', second ring 5/64'', Oil ring 3/16''. Says 3.736'' Bore
-Jegs throttle body spacers
-Accell Performence Fuel Injectors 26lbs
-Edlebrock High performence In tank fuel pump.
-MSD Ignition 8.5mm Spark plug wires, Multi angle
-Accell Distributor
-Accell distributor cap & rotor
-Comp Cams its a Thumpr Hydraulic flat tappet cam nitrided Adv/Dur-295/313, RPM range 2500-6500, Intake/Exhaust lift: .500/.486

Also I was thinking of getting a lightweight flywheel but since all the power I'll be gaining is it safe to get a lighter flywheel because can it spin too fast?? I am getting all of this off of jegs.
How much of a gain do you think I would get off of all of this. Reason for the distributor and cap is because i want the best spark nothing cheap and I dont want anything to happen if im not getting a good spark.

 

TTT help please!
