David - hope to eventually get to headers, ported plenum, Haibeck chip, and maybe a set of 4:10's. It has a B&B exhaust on it already. I've ordered a few things from Jerry already.


If you are "in there", we typically change out PVC hoses and the valves. Very inexpensive and better than OEM. (Jerry's gaskets again)

The original PVC hose are old and usually very soft. Good idea to replace

Nice looking Z!!! Highly recommend 4:10's! One of the best upgrades!!

I'd also recommend a short throw shifter. (Hurst or bill Boudreau).

You will LOVE the addition of headers!!! Great sound and 20 rwhp!!
