R90S tachometer ratio 2:1?
Posted: Thu Jun 18, 2020 1:53 pm
Can anyone confirm if the tachometer ratio is 2:1 or something else?
I have a R60/2 conversion with a 1975 R90S engine and would like to add a tachn. Blue Moon sells tach's for /2 that may work and come in either 2:1 or 4:1
Thank you for the help
