Help Me Pick a Cam

[VendettaV8]

Alright so I searched and I found a Bunch of Cam threads.....

But it doesnt help me pick a cam....

--------------------

Im looking for something this that is near streetable..... with a 2800 stall, and 3.42's in an A4..... Longtube headers with 3" exhaust...... and would have the computer tuned by Mail...... Possibly buy heads later this year.....

I Was make as much Hp as possible without sacrificing Torque. Id like a good Low end/Mid Range Camshaft.... I Dont want to Spin the Engine high because its got over 100k without a rebuild. So around 6200 or so is the highest id prefer.....
-----------------------------

Referring to Ls1tech's Cam Selection guide I was reading what they had to say about each cam and the following cams I was wondering if anyone had any experience with..... I wanna know more about the amount of power made and what times people have made with them.....

-----------------------
XFI 466: (218/224 .570/.565 113lsa) w/ 1.6RR's
A newer grind from Comp Cams. It utilizes their very aggressive XFI (Xtreme Fuel Injection) lobes that are good for increased power over older technology lobes like Magnum etc. Along with excellent drivability it exhibits a very strong mid-range with a good low-end and moderately strong top-end. Essentially a beefed up LT4 “Hot Cam” and cc502. With its 113lsa it takes a more trained ear to know that it’s there making it a decent “sleeper” cam. Note: Due to its very aggressive lobe design, requires the use of “Beehive” valve springs.
Pass Emissions?: Yes
Shift Point for Maximum Performance: 6100-6200rpm
Idle Characteristics: Smooth Idle
M6; Require Gears?: No
A4; Require Stall?: 2500+ Stall Speed

Crane 227: (210/224 .511/.553 112lsa) w/1.6RR's
Good proven performer on stock heads. Stock LT1 heads have restrictive exhaust ports relative to the intake ports and the 227's wide split in duration helps balance that out. The 227's low-end power starts low and is consistent through the entire mid-range making it a popular choice among guys with heavy B-Bodies. Will have stock like drivability and is known to be a torque monster. Lope is not very noticeable making it a nice “sleeper” cam.
Pass Emissions?: Yes
Shift Point for Maximum Performance: 6000-6200rpm
Idle Characteristics: Smooth Idle with a Slight Lope
M6; Require Gears?: No
A4; Require Stall?: 2500+ Stall Speed

LPE 211/219: (211/219 .530/.560 112lsa) w/ 1.6RR's
Has stock-like drivability and known to have instant torque in the low rpm's. Very comparable to the Crane 227 with its low rpm power that comes in early and is consistent throughout the mid-range. Lope is not very noticeable making it a nice “sleeper” cam.
Pass Emissions?: Yes
Shift Point for Maximum Performance: 6000-6100rpm
Idle Characteristics: Smooth Idle
M6; Require Gears?: No
A4; Require Stall?: 2600+ Stall Speed

The Crane Sounds like my Best Bet.....

Mods to come with this cam install would be 1.6RR's, Ls7 Lifters, Crane Dual Spring Kit 10308-1, Stock Length Hardened Comp Pushrods, New GM Timing Chain.

The Crane looks like it will get you what you are looking for though it's smaller than a hot cam.

Most people around here (I have no personal experience with it) seem to love the CC503 as a good middle of the powerband cam. The Hot Cam would be another good choice that can be purchased relatively cheap.

Just my $.02.

I guess im not 100% sure, I wont want to spend money on something that isnt going to show any improvement either.....

would you guys upgrade to any of these cams?

I want the low end torque still... but I know I cant rev too high kuz of the stock bottom, stock heads and high mileage.....

im actually lookin at gettin a hotcam amd my engine has 145xxx on it..

[thumpinglt1]

you need to go with the cc503, i love mine good power everywhere. if you went with that crane or the hotcam you will always want a little more. if i could go back i would go one size bigger

Why not go with a custom grind? That way the cam will be spec'd to your mods, motor, and goals.

I have the LPE cam listed above and its def. a improvement from stock, lots of torque down low, no surge or anything you can cruise at idle rpm etc. It pulls above 6k, i usually shift at 6k.

It has some lope, its not much but you can tell its a cam in there.

Fun little street cam!

You'll probably get a lot of differing responses to your question, so here's mine. A lot has to due with the cubic inch displacement of the engine and it's intended use.

Since my son's is a stock CID (350) and is a daily driver, those features govern my selection process.

I'm in the parts buying stage for upgrading my son's 96 Vette LT1. FedEx delivered the new heads yesterday and for the past couple of weeks I've been researching cams.

As a background, I'm 64 years old and have been screwing on these suckas since I was in my 20's. I use to build BB quarter mile engines for several racing teams that ran mid-8s are around 150 mph with ONLY ONE CARB, 20 years or so ago. I've changed so many cams in my own personal cars that I can almost do it blind-folded.

I said all that to say this: I've tried a LOT of different cam profiles, always searching for that "little bit more". What I learned was that, at first, I - like many others - over-cammed the engine. Too much duration and wrong Lobe Seaparation Angle.

I found that I was ALWAYS happier with a cam that was, perhaps, a little too small (short on duration) than one that was a little too big. Most guys still cling to the BIGGER IS BETTER train of thought, but I've found my car was MUCH MORE enjoyable to drive with I resisted that temptation and stayed on the short side in choosing duration.

So, since I'm doing a head and cam change on the 96 LT1, Monday I'm ordering a custom grind from CompCams. I'm going with their CRC lobe profiles, which you only find in the back of their catalogs.

I'm considering two grainds: Going with 218/224@ .050 using lobe numbers 3313-3314. With Scorpion 1.7 RRs I'll have .561/.570 valve lift OR 214/224 using 3190-3314; with the same rockers I'll have .600/.570 valve lift. Between now and Monday I'll make up my mind on which one.

I'm going to keep the grind on 113 LSA to maintain a nice idle with no surging, which is common when the cam is too long in duration or has too tight a LSA.

These is just what I'm going to do.

Hope it helps.
