4.10 cruising speeds

How big of a hit does the 4.10 install do to the car's top end?

Approx. what rpm will the engine sit @ going 85mph in 5th gear?

RE: 4.10 cruising speeds

What size tires are you running? There's a spreadsheet that calculates that but requires gears AND tires plus manual or auto tranny. I'll assume you're a GT and not a V6

PM me with your e-mail and I'll send you the spreadsheet. I can't attach an excel file on the forum.

Post the answer to the question and any info you find out, as it will be helpful and will prevent a wasted thread.

Plus, I am interested in finding out the answers and any additional info as well.
