[QUOTE="powerlifter405, post: 1504137, member: 2044"] I put 430's in my 7.3 6spd and in retrospect it did just fine what I did w/ 3.73s it and 35's. I found that 35's and 430s' wound it up a bit too much for hwy as I like to do 5-10 over. 80mph w/ 430s killed my mileage down to 15-16 IIRC. Before the swap I was getting 18-19 at the same speed. If you're pulling a trailer you might benefit but even w/ my current setup I pulled around 10k from S. TX up to NE and even stock tuned it ran fine. Using the tow tune was a really big leap. Just my experience but I'm trying to figure out why you want rpms for the hwy?? good luck [/QUOTE]
