I am looking to do a cam change on my 88 iroc, it has a 355 roller motor, all forged bottom end done right. But still need to do the top end as money allows, it still has the stock TPI but ported to the max, with 083 cast heads ported to the max as well and running 1.6 roller rockers with 10.63-1 compression. I am leaning towards the ZZ4 cam just to get a bit more power right now and heard it is a desent cam to upgrade too while still being on the mild side. Question is could i run that cam without it causing problems with my stock computer {it does have a ADS chip installed but thats it}. I have a AFPR which is set at 60 psi {seems to run the best there} and with a 150 shot of NOS seems to need it. The specs on the ZZ4 cam are 208/221 Dur @ 50, 474/510 lift with 1.5 rockers and 505/544 lift with 1.6s, 112 LSA. Any help would be great, Chad

 

Not a bad cam. I run a zz4 crate and it does not wreak havock on the ecm. IMHO I would go hotcam kit with 1:6 rollers. Want to buy my zz4 cam? got 20,000 on it. I stabbed in a hotcam

 

ZZ4 is a good cam for a daily driver mostly stock 350. It is pretty weak though. You might try something around a 212/218 cam. I think the LT4 is for a ported/siamesed aftermarket TPI set up really.

 

Irocdaddy, how much do you want for the ZZ4 cam? I found a company that does custom chips for 150.00, so i my go a bit larger but just incase. Thanks Guys Chad

 

Sorry for my lateness Chad-

I haven't fired up my car yet after the cam swap. If you go ZZ4; you can have my 20,000. mile cam for 100.00 I have paypal acct. as well.
