i will check the linkage, but i no that i have plenty of pedal left even when im pushing 2200-2400 rpms and it feels like its had all it wants. the pedal still has some left, but the motor seems like its had all it can take. i will still check the linkage however. i think what i really need to do is check the fuel pressure and do a valve job, and see what that buys me in the top end of things. thanks for the advice fellas. anymore is greatly appreciated.
