Need help choosing a cam
First off, why is a rolling cam better than a regular one? Here are specs on the ZZ9 cam:
ZZ-9 Hydraulic Roller
Intake Exhaust
Advertised duration 282 287
Duration at .050 212 226
Gross lift .483 .520
Lobe separation 112
I want the ZZ9 cam , but I am not dishing out $375 for it. I'm pretty sure Crane Cams makes it anyway. I was looking through summitt and jegs today and came across about 5 different cams for my application. Please tell me which ones would work (and which ones would be the best) on my 92 5.0L TPI 5speed. My mods are listed below thanks.
Should I go with any of the following..which would be the best:
CRANE CAMS 270110592= 284/290* (adv. duration), 480/494 (gross lift)
CRANE POWER MAX 270109831= 284/292* (adv duration), and 509/528 (gross lift)
CRANE CAMS crn109831 = 222/230*(duration @.050), with 509/528 gross lift
CRANE CAMS crn109831 222/230 (@.050) with 509/528 gross lift
CRANE CAMS crn109841 234/242 (@.050) with 539/558
Can I use my stock rockers with a new cam ?

A roller cam is far superior than a typical hydrolic cam. The roller feature allows a more rapid lift, and longer duration, plus less friction.
As for your other questions, sorry, I don't know which is best.

The ZZ9 cam is over priced, but so are all of the TPIS parts. The LT4 cam, the one I am buying, is a better cam and it sells for $180 from Salee Chevy

Can you tell me more about the LT4 cam? What are the specs on it (adv duration, duration at .050", lobe sep, and gross lift?)? Is it a rolling cam? Where can I get it?
thanks
