Making my Stock Ford tach work with an LS1... I have a 1988 Merkur XR4ti. I'm planning on installing a LS1 into it.
Its has the typical Ford 4 cylinder tachometer that just uses a green wire ran to the coil to give signal. I've heard you can use Ford 4 cylinder tachs with LS1 electronics.
Is this true? If so please point me in the right direction...

Say it ain't so!!! ^^^ 
My scan tool and HPT both report about 150 - 200 RPM difference than the tach in my Thunderbird which seems to also react slower than the engine across the RPM range. If I want accurate I'll go aftermarket, but I wanted stealth and low budget.
I got the impression from the OP's first comment an aftermarket or non-factory tach was not on the menu unless it had to be.

Also I plan on having a shift light with the digital tach in it concealed somewhere. Havent decided yet.
