These videos are so awesome! Good job 👍🏼 Enjoyed every second of it! Definitely deserves more views!!

Hey, thanks a lot! We've been talking about making more when we get the time free.

@@rearwheelperformance torque converters and stall speed is one thing I feel that a lot of people including myself don't understand to the fullest. I mean i understand the basics but I'm sure there is a lot to learn. Thanks for taking the time and effort on making these videos.

@@MartinAguilar213 Yeah, automatics and torque converter stall dial-ins are definitely magical creatures that can be hard to master. Having tech discussions with auto trans builders and racers can get pretty in-depth.

I have a 1974 lincoln mark VI with 2.75 gears, 9" rear. I'm planning on putting 4.86 gears in it.

[@rearwheelperformance]

If it's running a C6 and a big block it will be nice off the line, but hard to imagine 4k+ rpm highway. A ton of torque, sounds interesting!

I have a question got a 2011 cvpi looking to swap gears it got a 327 it's my daily driver I do alot of city and interstate driving whats a good gear to go with 373,390 I know 410s is too high for interstate

[@timjasmin80]

Did you run into any abs issues or cruise control/ traction control issues?

I have a 1987 chevy silverado short bed. 305 5.0 tbi and a 373 ratio on the diferential. I want to change it to a 410 would it give better mpg?

[@rearwheelperformance]

It may, depending on the transmission, tire diameter, how and where you drive the most often, and if it puts the engine in a more optimal/efficient rpm range. If it feels like a dog driving now, then more gear will usually help.

I have a 2002 3500 Chevy cargo van w/ the duramax diesel. Will a different gear in the rear help with mpg plus torque? What would you recommend

[@rearwheelperformance]

Re-gearing may be able to help. Diesels have such a narrow and sensitive rpm range, it is even more critical to work through the numbers. We would recommend looking for forums and/or Reddit to see if you can find other truck/van owners, with you same engine/trans & similar diameter tires, to see what ratios are working for them. Obtaining better highway mileage is usually achieved when the engine is operating within its most efficient and optimal rpm band.

Great video guys

[@rearwheelperformance]

Real cool, thanks!

[@timjasmin80]

So, with 18% gear difference.. if you are reading mpg in the dash without correcting the speedometer odometer, your mpgs and odometer will also be off by 18%
