I recently bought an 86 Berlinetta w/ 305. I plan on dropping a 350 or a friends 385 Fastburn...but I need the digital dash recalibrated or whatever to display speeds above 85. Any speed above 85 makes the speedometer blink at 85. Does anyone know how to do this or of anywhere where I can find the info?

From what I know, the digital dash is controlled by the ECM. I suspect that the 85 is comming from a speed limiter. Check out www.thirdgen.org (http://www.thirdgen.org) They'll blow your mind with computer stuff.
