Vette(s): 1970 white/blue AC man, zz4

Hello Everybody,

I'm pretty new here (few minutes ...) so I hope I'm doing it right if not please be patient with me and point me to the right direction - Thanks in advance.
 
I just finished the instalation of a ZZ4 engine into my 70 Vette.
 
I was wondering if any one of you did something similar before since I have few technical questions.
 
Thanks,
 
Ron

Thanks Dave.
One of the problems I have is how to connect the RPM Gauge to the new distributor. I'm not sure if in 82 they still had the same system in place but in my Vette (70) it is a mechanical cable that I just don't have where to plug in the new distributor.
Any idea how to overcome this ?

There are still some companies that make a distributor with the cable drive setup, I believe MSD has one that will work. If you still have your old motor you could use the distributor out of it.
Other wise you would have to replace you tach with one from a newer Vette, I think they started in 75.

Ron, if you have to change the distributor, don't forget to insure you have the right drive gear for a roller cam, it's a different composition.

Forgive me if you're already aware of this, but it was worth mentioning. A billet cam, such as that in the ZZ4, requires a softer metal drive gear or it will chew up the cam. Comp cams makes a very nice after market gear, but they get about $110. for it. It wears much better than the bronz type. You should be able to use the gear off the distributor that came with the ZZ4 (just drive out the pin) it wouldn't work for the standard cast steel cam anyway.
