I am building a 383 stroker for my 96' Z28. My question is what cam should I do with? I want to good NA power, but it will be sparyed at the track some. I was thinking of going with a CC306 cam with 1.6 rr's. Is there anything out there bigger and able to produce more NA power for a 383 stroker? I haven't looked into to many yet and was just wondering what some of your alls experinces are.

Thanks

 

CC306 should do you pretty well....

There is a step up from that...a custom grind I believe from Comp Cam...I don't remember the #'s...

 

306 will be pretty tame in a 383 IMO.

 

you can go as big as you want.

cams dont really have levels- just different specs (opening & closing points centerline, LSA, lift, durration, overlap ect)

A lot of guys like big durratoin cams, especailly if your heads dont flow so well. Many guys are going big lift. I just did both

disclaimer-
with cams, especailly cams- as its been pointed out on 3,513,556,513 times and counting- bigger isn't better. For starters try choosing a realistic goal, a powerband, and how much "tameness" you are willing to sacrifice. Then pic a cam.

Blindly picking a cam off the shelf due to populatiry is just stupid. I can train a monkey to go pick a cam up off a shelf. Does that make him an engine builder. More importantly does that make me the head engine builder and mechanic or a teacher?

 

Very good point Trey.

ALSO... When choosing a Cam, u should also keep ur Valvetrain very close in mind.

I personally would never just do a cam swap without changing setups in valve-springs, and possibly Lifters, Rockers, Pushrods, etc. When u decide which cam to use, then it's time to structure out what components ur gonna need in ur valvetrain in order to maintain specific lift.

Another factor to consider is Heads. If ur doing a new Cam setup, and u want to maximize horsepower and efficiency, your going to want your heads to flow accordingly along with proper Valve sizes.

This all goes along with Trey's idea of being an engine builder and not just choosing parts with high numbers

 

Current setup:

LT4 Hot Cam kit
LT1 p/p heads - don't know the flow #'s
58 MM TB
Other bolt on goodies.
12 bolt

Current state without the nitrous it dynoed 374rwhp/356rwtq, which people tell me is good for a HotCam.

Going to a 383 stroker with using the LT1 p/p heads and other bolt on stuff I already have.

Eventually I will be p/ping a set of LT1 Impala Cast Iron heads with upgraded valvetrain. Just don't have the money to do the heads and the 383 right now.

Should I wait until I get my heads p/ped and then look for a cam to go with it or get the cam now with the 383 and p/p my heads to match the cam?

Also I don't want a cam that is going to be too tame for the 383, but I don't want too much of a radical one either.

TreyZ28 what are the specs on your cam if you don't mind sharing?

Thanks

 

236*/242* with .608''/.613'' lift after rockers.

Keeping a valvetrain together will cost you. My springs were over $250 and my lifters/pushrods were around $320 together- or so- i dont know i forgot. I'll remember damn quick when the bill comes.

To use the words of a wide old man-

with cams, everything is a trade off. there are no freebies. The only trade off for lift is valvetrain stress. if your valvetrain can take it- lift away

Bauer guys seem to agree. Lift is your friend so long as your valvetrain can support it

 

Cool thanks man. Valvetrain is going to be upgraded with the cast iron heads so I think I will wait on my cam until the heads/valvetrain are ready to go on.

 

Is that comps XE grinds or something else?

I though the XE 236 was .556 with 1.6 rockers
and the 242 was approx .575 with 1.6s

Are your lift figures with 1.7 rockers?

Sorry, if I'm missing somthing. But, I'll be running a similar XE came soon, and was just wondering about the lift.

 

maybe its the HL or some other series?

www.cmotorsports.com

look under thier cam packages, you'll see it

 

i think the XE 236/242 would be great for a 383 IMO.

why on Gods earth would you want cast iron heads??? if you made 374 rwhp with a hotcam... i see no reason those heads cant go on a 383! FYI stock heads and hotcam is lucky to see 330 rwhp.

 

iron heads on a z28 is a downgrade, not upgrade.

im gonna run the 230/236/112 in my 383

 

Was going to go cast iron because they can be ported more then aluminum heads. I might just open up the aluminum heads some more with bigger valves. I am still running stock valvetrain with the aluminum heads. They are heavier, but they will/were going to be opened up more then the aluminums.

 

XE 230/236/112 in a 383? Why not a bigger cam like a CC306...?

 

I poked around on the site a little and didnt find the cam (but I dint try that hard either. )

I did order a double roller timing chain from them yesterday though. First time to do business with them - seem like nice folks who know what they're talkin about...
