MSD makes a tach adapter that will work with this tach. 

Congratulations DrDave. 

That is my 1965 421 that I had Butler Performance bore and stroke to 453

It’s going into my 1965 GTO

I nominate my 65 GTO as car of the month.  I bought it last October and have upgraded to disc brakes and replaced all suspension front and rear.  Added all new steering components and new tires and rims. I then had new posi and 3:90 gears installed in rear.  I bought new m22 4-speed and hurst shifter. Then I installed a Butler built 421 tripower motor that produced just under 500HP with 544 torque.

Love the 1065 GTO

I like the 67 GTO

Awesome GTO
