helllo, i'm pretty new to building motors and i don't know what to look at as far as cams go but i was wondering what you guys thought about these specs for a cam.

.510 INTAKE LIFT / DUR.@.050 .230 DEGREES

.520 EXHAUST LIFT / DUR. @.050 .236 DEGREES

LOBE SEPERATION IS II0 DEGREES 112 LOBE SEPERATION AVAILABLE UPON REQUEST


my motor is a 94 lt1 and im doing the vented opti conversion. the motor is bored over 40 and the heads are stock p&p w/ 918 beehive springs.
this isn't a daily driver but it will be driven in town. i want as much power w/ descent drivability as i can get... any suggestions?

 

my favorite off the shelf cam is the cc503, makes great power with stock heads and performs even better with ported ones. I'd say away from the old magnum lobe comp cams such as cc305 and cc306. GM847 seems to be a love/hate cam imo. but for the best results you'll want to go custom, prepare your flow sheets for heads and engine specs to get best results.

comp cams I believe has a program that helps you decide on a cam on their website I believe

either way you decide to go I'd recommend ditching that 2100 stall and stepping up to atleast a 3200

 

I don't think the cc503 would be best for him because he already has p&p heads, and most people who use the cc503 use them for "cam only" or stock heads. Im no cam expert so I can't say much about the one you chose. Hopefully someone else can chime in

 

If you don't want a custom cam then get a cc306 used from the for sale section. Proven cam and will give good results. It's pretty tame too considering.

 

I wouldn't recommend that cc306 honestly, people have gotten better results from smaller cams with better driveability. the cc306 is one of comps first grinds for the lt1 and is actually just a gen 1 carry over

 

I never said it was the best all out choice but as far as common off the shelf grinds it's probably one of the best.

considering the variances in "ported heads" I've seen over the years I'd rather put in a cam that performs awesome with stock heads on car with simply "ported heads" than a cam that REQUIRES porting/extensive porting to perform. that is unless he has some flow #'s from the porter than I'd be all for going bigger. it's better to have a cam that is too small for your heads than too big

 

www.advancedinduction.com they have great custom cam profiles to suit your needs

 

I have a 3800 stall i can switch 2. i found that cam on ebay for a descent price. thats why i threw up those specs. i was considering the cc503 from reading. i didn't know how that cam compared to it. i have an lt4 hot cam already purchased but i know i want to go bigger having the p&p heads. and i don't have a flow sheet for the heads. i can tell you that the bowls weren't polished j/ the ports. and a 5 angle valve job.. thanx for all of the replies

 

how does that cam i first posted the specs for compare to the cc503 it has a lil more lift. i dunno if thats necessarily good or not... what about the duration... if somebody wanted to give me a little cams 101 class thatd be cool 2

 

Go with an AI custom.

 

I looked at the advanced induction page. and i'm not sure i know enough about my motor to get a custom cam. i don't have flow sheets . i dunno what all is needed. there page is pretty impressive. i'm lookin at either custom or the cc503

 

I have the 503 and love it. Stock heads and runs like a champ. Unfortunately I don't have any numbers yet to back up any claims. Personally if I had the money, hence the 503, I would go with an AI package. Contact them, tell them what your goals are and what you have now and I'm sure they can get something you'll be happy with. I have seen/read nothing but glowing reports regarding them. Just my $.02.

 

get the 226/234. Plenty of cam. or the one smaller than it.

If you call in and talk to them they will tell you exactly what will your fit you needs, likes, etc.

If you want a shelf cam the 503 is going to be hard to beat. Get it on 112, 114 if you really want driveability and emissions testing.

 

actually the 112lsa cc503 is a proven smog passer with a good tune

my car made 325rwhp through an unlocked stalled auto, with midlength headers, dead of summer, on a 135k+ mile motor.

what are the specs on the 226/234 cam?

from what you say about the heads it sounds like you have gasket matching and a little valve work.

There's your cam guide. Its based on LS1 cams as far as when they mention the name of a cam and how it performs but a cam is a cam. The cam you originally mentioned is a decent amount bigger then the cc503. It has more lift and more duration. Thats going to make the powerband be a little later in the rpm range so it all depends on where you want the power to be and how high you want to spin it.
