Injectors? I am gettin some bigger injectors for my 355, and i need to know if lt1's are high or low impendience, and the car seems like it falls off on top end like in 3 and 4th gear abour 4k rpm, is it possible it is running out of fuel?

Why do you think you need bigger injectors? maybe yours are dirty and need servicing or same size replacement. You can go for bigger injectors but that will require a retune.
If you're sure the injecters are clean and the fuel pump is fine, find out what's the duty cycle and if it's higher than 90%, get bigger injectors.

its a 355, 11.1 compression forged pistons, LT4hotcam (the whole kit), fully balanced internals, stock heads ported and polished, 3 angle valve job, port matched intake manifold, long tube headers, 3inch true duals, MSD pro billet distributer, intake elbow, and the PCMforless tune! BUT the things that are killin me is i am running the stock throttle body, intake, and injectors! but i will def. check fuel pressure and the motor only has 1500 miles on it and the injectors looked good when i put them in! Thanks for the info guys!

The motor is a N/A LT1, .060 over, stock lift, and even has stock stamped rockers! Sorry, but no BS here.
