Cam question
I am gonna put together a 383 for my '85. I am going to put on my ported and polished heads with 2.02" intake valves. Stock exhaust. Will probably remove the MAF screens and eventually put in a K&N filter with a cut lid. I have a cam that I would like to put in but was curious what others thought about this cam. It is just a hydraulic cam
This is an Eginetech ES1014R cam
__________INT.__EXH.
.050 Dur___204___214
SAE Dur____276___288
Val lift_____420___443
I have to pass Ca. emissions with this car. Any thoughts on how this setup would work out or hp estimates?

My opinion:
It's not much different than a stock 350 cam. So for a 383 it'll be too short in duration. Defintely not enough cam for a 383.
You can choose a better cam, with more duration and lift and still pass emissions testing.
There are several that will do the job, including the ZZ9, two of LPE's offerings, the 211 and the 219, etc. Keep the .050 duration under 220 @ .050 and the lobe separation angle at 112 or higher

What about -
__________Int____Exh
Dur________270___290
050 Dur____214___224
Val lift_____440___460
Lobe seperation___112
I have no clue about selecting the proper cam. I have to depend on others for this so I thought I would poll the experts. This is an over-the-counter cam from Schneider Racing Cams.

Well, is this the last modification for this engine, and will you be sticking with the TPI-style intake or switching to a Superram or Miniram later?

A modded TPI with 1.6 rockers and a 211 or zz9 cam should make a great street motorthat easily passes CA smog.
TPI cars like cams in the 208-220ish range unless you go SR.

I don't plan on any other mods other then possibly changing the mufflers. I am only doing these because I have these parts. I am gonna stay with the stock TPI and will get a chip burned for this setup. I am currently running the Ford/Bosch 19# yellow top injectors in the car.

And, its basically the same cam as Schneider Racing cams from the specs above. Heck I didn't notice either, guess I am spending too much time bent over a fender these days
I would find the biggest cam that will pass emissions for a 350. Considering you are building a next step up bigger motor that big cam for a 350 won't be so big in a 383.

Iam with tjwong and jake highly experienced members,
i just did lot of upgradation for my 85 vert and bought
Tpis 700-135 flat tappet cam 224/224 and .495/.495 lift
very happy with it little lopey but i like that little rough idle
But if i were u i will buy retro fit lifters, shorter pushrods,
and right springs and convert it to a roller block and either
go for ZZ9 cam or Lpe 74211 inorder to stay with TPI setup
and still be able pass emmsision.
Probably 74211 is best as it cost less than ZZ9 cam.
Also if u want to convert to roller than
Lpe offers Retro fit lifters for $499.00 but
Tpis offers for $299.00 u decide other parts not that expensive
unless u want to go comp cam roller rockers $269.00 for 16.
sami.

This will actually be a hydraulic lifter engine. I have a shortblock from an 87 Vette with a roller cam but I didn't want to spend the money to stroke that motor since I have the 383 allready built. It is an externally balanced two piece seal motor.

I am running TPIS cam on my 350 engine and it seems to run great. I dont have emissions to worry about though.
its 224/224 @ .050 - .52-.52 lift (with 1.6 roller rockers).
Though I imagine it'll like the eventual Superram more, it responds well as is.
This is a flat tappet cam which is what the 85's come with. I dont think Roller cams were installed until 87.

Admittedly, I'm biased on this particular point, but in choosing a cam company, I only consider CompCams, period. There are a lot of reasons, like their cutting edge technology, quality control, etc.
I'm not trying to bad mouth other cam companies, but why not go with the best cam maufacturer in the industry, CompCams. He**, even Harvey Crane says CompCams is. I definitely respect a man who's that honest about a competitor's products.
