What cam did you use? Did you reuse the ZZ4 timing chain? If so, any problems afterward?

It was big, but I used a com cams LT1 cam. The 306. It's 230/244 and .510 .544 on a 112 LSA. I liked the wide spread for the nitrous I'm using. I did reuse my timing chaing, but there were very low miles on it.

If you do change out the chain, be careful. The ZZ4 timing chain cover might hit some aftermarket double roller chains. I had to get one from the auto parts store that was a little deeper. No big deal.

Looks like you have a nice ride. I'm running a 355 w/ the HSR and commander 950 unit.
