ZZ383 cam advice needed

I just ordered the zz383 from Sallee Chevrolet. I was wondering if I should keep the cam it comes with, change to the hotcam, or go with the aftermarket comp cam. I read a few posts about the comp cam upgrade. What should I do?

Alot of choices out there. I'm using a Lunati roller in my zz4. Check out the voodoo rollers.

If you want some lope, stay away from the Hot Cam.

Re: ZZ383 cam advice needed

I think that would be a good choice in a 383. I would make sure I had compression of 10 to 1. Do a search on the GMPP crate motors on this site. Lots of info.

Not trying to pop your balloon, but you might want to take a look at this thread and read the last page or two pretty closely.

Re: ZZ383 cam advice needed

The zz383 is 9.7:1 compression I'm not familiar with the comp cam you listed , but that engine comes with a .509 lift intake & .528 lift on the exhaust.

Also 1FastZ is right they are behind on there motors. If you're not in a rush no problem, but if you're chewing at the bit it'll be a long wait. I had ordered a zz383 (not from salle) back in january & after waiting a month & having no idea when a may show up I started looking into building my own. I know everyones situation is different, but you can build a motor to make that much power or even more for less money. Remember also the zz383 only comes with hyper pistons & pm rods, but does come with a forged steel crank. It's a real nice motor don't get me wrong just not as good as a forged rotating assembly.

Just my opinion

and yes I canceled the order & will save approx $1500 building my own

Re: ZZ383 cam advice needed

I believe that cam in the ZZ383 is a Edelbrock roller. One of the same that Edelbrock puts in their crates. I'm not 100% though.

Re: ZZ383 cam advice needed

Compression is 9.7:1 with its gm stock hydraulic roller cam. Would this change if I went with the Comp cam? I'm willing to wait a few months if necessary because I have heard good things about this engine.

Re: ZZ383 cam advice needed

The cam is a gm unit

Changing the cam won't effect compression

Re: ZZ383 cam advice needed

Should I even change from the gm cam to the comp cam given the $250 price increase? I want the nice muscle car sound not a mild stock sound.

Re: ZZ383 cam advice needed

Find out the LSA and duration of each cam. This should help you make your selection.

Re: ZZ383 cam advice needed

I just called Comp cams today. They told me that there cam would work great. This is there Extreme Cam part number 08-432-8. I'm just confused about whether to go with this cam, or save some money by using the gm cam it comes with. If anyone out there has the zz383 can you let me know if there cam is good enough? or can it use an upgrade?

Re: ZZ383 cam advice needed

I ran the Hot cam in my 383 for awhile and was very pleased with it. The hot cam is very similar to the zz383 cam - it just gets its lift from 1.6 rockers . Personally, I'd run it as is. But if you absolutely have to have the rough idle, then swap it out before you install the motor.

Re: ZZ383 cam advice needed

will it effect performance? That is, going with a higher lift cam.

Re: ZZ383 cam advice needed

Yes, it will affect performance. Not sure what you are asking. The more duration you have the more lope in most cases. Duration can affect drivablilty. A 230 duration cam would be about right for your motor. Either the GM cam or the Comp cam will have some lope. I would go with the Comp myself. Do a search on hyd. rollers for a SBC.
