Should be the same. The standard for speedos, is like 1000 rpm's of the input (or I would imagine pulses from the vss would be the same) would be 60 MPH. I'm not sure on that, and I know GMTech knows, that's where I got it from!
Is this some sort of rare stock piece, or aftermarket?

Autometer has had the 160 and 200 mph electro speedos for years.
IMHO the 140 stock speedo is plenty. If you looking at a speedo at 140+ mph.....
WTF are you doing????? The is NO time to be checking the speedo. Maybe the oil temp, oil pres, water temp, then you wanna check your speed????
Better be in the Silver State Classic. Even John Lingenfelter will tell you there is NOT enough time to check all vitals at TRC at 200+ mph.
