All that said, 720 (Former numbers) to 740 RWHP is crazy for bolt ons...Never heard of that before and I've seen and read about hundreds of built LT4 engines. Usually you have to have a cam to get over 670ish RWHP. Don't be upset with your numbers, but I would recommend you grab a dual nozzle meth kit for your build if you want some more power.
I would agree with Ktt, his car is being pushed to the max (Supercharger RPM wise) and likely Matt tuned her pretty aggressively as well.

ah i didnt realize he had upper and lower! thats nuts! i enjoy where my car is at now making 653/664 and the car flys! i dont have any interest in doing a meth kit. its just a fun car and i want to leave it where it is. its reliable and fun to drive
