What is your top speed? Post your MPH and Setup! - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hey guys I just wanted to get an idea of how much power we have out there in the squarebody world.

WHAT IS YOUR TOP SPEED?

WHAT DRIVETRAIN AND UPGRADES ARE YOU RUNNING? (pictures are nice!)

(If you have quarter or eighth mile times post them too!)

thirdstreettito · 08-18-2010, 10:32 AM

The suburban in my sig. I hit 110, according to my calculations it will hit 128 before governor. I stop at 110 because the tires are rated at 112. Try explaining that to dad. She hits 110 real easy and rides and steers like a upper-class sedan.

Billetmaster · 08-18-2010, 01:04 PM

88 mph. And then...

piecesparts · 08-18-2010, 01:15 PM

With the eighties models, where the speedo stopped at 85 MPH, the fact that the speedo in in the OH WOW section means very little, but the guy with the Camaro running at 127 MPH, said I was pulling away from him.

team39763 · 08-18-2010, 02:06 PM

Mine has posted a best speed of 109 or 110mph in the 1/4mile. That was with my old setup...stock smallblock with a aftermarket cam, TH350 and a stock G80 posi. It's faster now with the new setup, but I haven't had the speed recorded.

Low87 · 08-18-2010, 02:25 PM

Well, this may not count but the truck did hit this speed. On the way between home & college there was a 1/2 mile or so stretch, straight as an arrow and about a 20 degree downslope the entire way.

I was running along side my friend's 280Z and we got to 135 on his speedo. I let off because my truck started to float. It was in a reasonably fresh 305, 700R4, and the tires were rated up around 160mph.

What Cam, Rear end Gears, Tire Size, are you running? long bed, or Short bed?

Restrorob · 08-18-2010, 05:48 PM

Any of mine only do 5 MPH over any posted speed limit.....

*78 Chevyrado* · 08-18-2010, 09:03 PM

hmmmmm ....well ive only had mine up to 65 so far . started driving it this week after bringing the 6.2 diesel back to life after a year asleep . wont be getting much more out of her until i either change the 4:10 gears or get an overdrive tranny . poor gal revs 3000 at about 60mph .

bucannon · 08-19-2010, 01:35 AM

i hit 90 with my 80,000 mile 305 with edelbrock 500cfm carb and a 700r4 with 2.73 gears and 33" mud terrain tires. it was scarry ha ha

von guido · 08-20-2010, 12:45 PM

at maxton i hit 122.8. That was with 3.08 gears a 30.2 inch tall tire and a mild 454/th350. Ya cant expect much top end out of something with the aerodynamics of a shoebox.
That being said, i am going back with a turbo'd 468 and a few aero mods and see what happens!

rblcori7 · 08-20-2010, 12:58 PM

I hit a whopping 75 mph today on the interstate lol truck in my sig

81ratrodc10 · 08-20-2010, 05:17 PM

Old, Tired, its only got 6/10th of a mile on it??

85burb · 08-20-2010, 06:21 PM

My poor old 85 burb with 4.10 and 700r4 had the needle strait down befor. Does not really notice hills at that speed. Was late...almost late for concert..

dropd80s · 08-20-2010, 06:39 PM

I have had my dually up to about 75 on the trailer behind my 02 cummins, lol. I have never even driven it

. Honestly, at the ripe old age of 25 I have lost a lot of interest in top speed. I usually drive about 1,500-2,000 miles a week and cant see throwing money away on a ticket. I'm normally 5 mph over the limit max.
