i drive alot on the highway at high speeds, i take alot fo 30 minute to an hour trips and the occastionaly day or so trip. i drive a NA thats been built up (see: http://www.supramania.com/forums/showthread.php?t=10934 for car specs) and if i do 85 im at about 3800rpms and 100 is about 4500rpm.......i know this is cause of the 4.10 gearing in the NA rear diff but is this bad for my engine to run at a constant between 3800rpm to 4500rpm i dont want to blow my motor or break anything else so am i gonna need to change out my rear end to get the abalitity for these higher constant speeds? i am planning on a 1jz swap but thats not for a few months before thats complete and im moving to florida before then so im gonna be doing ALOT of long distance driving.
