Cruise RPM and Transmission Selection
Posted: April 11th, 2013, 5:49 am
My conundrum:
As an avid offroading enthusiast im fighting the constant battle of crawl ratio and highway cruise RPM. My current setup is a 4.7, ax15, atlas 4.3, 5.38 gears and tires that measure 38" at street pressure. It is a large beast but my goal is to drive it, beat it, and return with no trailer. Currently my crawl ratio is an acceptable 90:1ish but 1st isn't where I want it. My cruise RPM @ 65 is 2300 in OD. I have a built to the hilt 727 sitting under my work bench. Having a converter would effectively add 50% to my crawl but make my cruise RPM 3000ish. Also, once the converter is at "stall" speed (highway rpm) its pretty close to 1:1. I feel like this should be ok considering fuel economy isn't a concern, but does anyone have experience with a stroker at these RPMs for extended periods of time, say 3+hrs? I don't have cooling issues. This also puts my engine at the top of its torque curve. Is this acceptable? Who has a stroker and stock 3 speed? Discuss....
