So I am supposed to put a higher chip in and take a chance of over-reving the motor and breaking it????

First no race motor has an EXACT redline, just where it stops making power. Yes if you are hitting the chip it is illegal. Now there is no way for NHRA to police and / or prove that you are doing it for that far down track. I have raced a few people that do hit the high chip. (being faster car) You are making up no ground between each other, then you make a huge move late. Kinda screws you up. But YES illegal

Chris: I realize there is no "SET" RPM limit on any motor, however when using FORD's you really dont want to push them much over 7500 for long unless you have a killer bottom end.... Unlike the Chevy, they just cant take the RRR's...

Like I also posted I dont know even if this will be an issue as I have not run the car on the stop yet, and will need to in order to run either S/G or S/ST..
