Was driving the truck 2 nights ago and saw some beautiful open road and it was about 45* so I punched it. passed 100 MPH and got the RPM's up to 5500 before I shut it down.
Got on to the web this morning and typed it in to a MPH calc, 5500RPM, Transmission: 1:1, Rear End: 3.73 Tire size: 31.6 and bam! it says i was doing 138MPH!
Was i really? or was it just lying lol

with the 3.90's and 29" tires 6000 is 135ish....so yeah that should be about right
it prob took a little while to get there i imagine...trucks are bricks lol
2006 silverado SS....Clifford Jr...turbo coming soon
1970 Chevelle ly6 swap....d1 coming soon
Probably close.
I've only taken my GMC to 115 and the Blazer still has the stock tune so it shuts off around 94.
it will do it, took mine to 7200 rpms in 3rd with 30" tires 4.10's 1.1 ratio put me at 152mph, fastest its gone is 162 with the 3.42's.

I am about 99% sure that calculator is only right if your converter is locked at WOT in 3rd gear. Which is not the case if you have a Nelson tune.
What about the time I took the '76 Delta 88 in "my garage" to 5400 RPM with a 29" tire, 3.42's, and a THM400....?
SCHWEET...!
