Top Speed Roughly??

[AustinDube]

What do you guys roughly think my top speed would be and i doubt it but it prob wont be able to make up highway speeds steady without raising the rpms through the roof. I got a 1976 Chevy K10 sm465 np205 12 bolt gm rear with 3.31:1 Rear ratio. 350 is a 4 bolt main with a edelbrock performer series fuel pump, and 1405 carburetor.

Don't know what your top speed may be but I will offer that my 85 has never seen over 80 with the BFG 33's.
Street tires would make a big difference.

Any gears, still need to know tire size. For instance, my 86 with 4.10's and 37" tires runs around a nice 2300 rpm at 60mph. my 71 (rwd) with 3.73's and 295/50/15's runs close to 3o00 at 60mph. Check out this neat little calculator.

What exactly are you asking? Your top speed? Or if you can cruise down the highway at a reasonable RPM?

I do 65-70 on the highway with mine. TH400 and 3.73's with 265's. Nothing the drivetrain can't handle easily.

if your looking for speed, it may sound dumb but you can download an app for that. my speedo doesn't work in my k10 so I use "ulysse speedometer" app on android

"Android Speedometer" is a good one too.

 

[AustinDube]

I believe I'd cruise pretty good too for highway speeds. I have new 29" michalen street tires for er

For the other side of the spectrum, my 74 does pretty well at 75 with a th350, np203, 4.11's and running 35's.

But she's always been happiest at 40-45 even before a lift and tires.
