Default LE3 cammed guys come in.....

Those of you with the LE3 package OR LE3 cam and diff heads....

HOW much power are you making?

He says 410-430rwhp on his site.....wanted to know what the average combo is putting out.

I am planning on the LE3 cam with my MMS Aggressor heads upon a soon to be rebuild. They flow 290 cfm on the intake so I think they will work just fine.

Right now I am producing 388rwhp/381 rwtq on these heads and a CC306 cam.

I am wondering if a change to the LE3 cam can get me up over 400rwhp.

you're not going to be getting an LE3 cam from lloyd without purchasing LE3 heads.

if you want a custom cam, bret bauer does the cams for lloyd, talk to him.

I have the LE3 heads and cam package. I'll let you know how much power I'll make in a few weeks it'll be a all forged 355, I plan on 415-425rwhp on my set up which includes all the bolt on's Lloyd and Bret recomends.
Later.

Why not?

Have you asked him before?

The car is a 6 speed.

My heads are just as got or better than LE3 heads BTW.

SO, if anything, I should make at least as much power as the LE3 package.

What valves do you have?? My LE3's got 2.05 1.60, don't take it the wrong way but LE3's now are flowing better than 290cfms or at least mine are.

2.02/1.60

I would like to see flow charts that support this (not that I dont believe you). If that is the case, I may be interested in the complete package.

just browsing, noticed your numbers. There are guys with 503's making your numbers, i would expect more from the 306, are you sure your heads aren't the weak link there?

Here is a link to a guy that had my LE2 heads flowed at a place local to him . . .

http://web.camaross.com/forums/showt...ighlight=Lloyd

28" flow #'s are a VERY small part of a working port and overall port shape and measurement in key areas to keep the port stable at working conditions (MUCH higher depression, constantly changing depression, air and fuel moving in pulses as opposed to a flow test at a steady suction, etc, etc) are MUCH more important and the flow #'s are justy along for the ride.

The flow #'s just allow you to see a problem and make sure the #'s keep climbing at .550, .600 and even .650 lift REGARDLESS of cam lift used. This assures you that the port will stay stable at high depression when the engine is running.

You want the port shaped right to keep the air moving at teh speed you want it in the key areas at high depression, even if that loses CFM on a 28" flow test.

2 heads with the same or similar flow #'s @ 28" can be produce VERY different results.

You will see about 15 RWHP over the CC 306 if you have a mono blade, ported intake, 1 3/4 LT's, 3" true duals and good tuning on a 6500-6800 RPM 355 but the LE3 cam makes ALOT more low and mid range power also.

You might see a lil more HP with more RPM or cubes but not much more.

My cams are designed for my heads and that is one of the reason I only sell them with my heads.

You should be able to get 410-415 RWHP with the CC 306 if you are planning on making 425-430 RWHP with an LE3 cam. There are alot of ways to lose HP and that doesn't mean the heads are the hold up. CAI, MAF, TB, intake, valve adjustment, headers, exhaust and tuning are ALL other things that can kill HP.

I have been running Lloyds stuff for years. I have always been happy with the way they performed. I got my first set in 2001 and made 395RWHP(UN-locked through an A4 and 12bolt) with out tuning.

We went back through those heads in 2005 for the 2006 season and went a little wild to make sure they would support the 30 extra cubes. The engine is setup to run N/A part time but take advantage of juice. I still drive it on the street alot also so that was in mind. This really tells a story. N/A the engine only made 420RW(Un-locked A4 12bolt) Peak BUT made over 50RWHP more Average HP then it did before and alot more TQ. The car dropped an average of 6/10ths so far and we are still tuning.

On the bottle the car is an all out animal

Our second Shop car has a set of Lloyds heads also and it dropped 3-4/10ths over any one elses heads we had used. I mean this car has had them all!

Listen to Lloyd and Bret and it is hard to go wrong

Here are some dyno results of my LE1 H/C.

http://web.camaross.com/forums/showthread.php?t=498427

The cam has less duration than the CC 503 and very tame to dive. It is mild enough to work with stock gears and no stall but obviously gear and stall will make the car faster. I am sure it is a blast with a TQ curve that flat and that much low end power while making over 380 RWHP.

58 MM TB, ported intake and some 3" true duals would put him around 400 RWHP and 375 RWTQ. VERY good #'s from a small cam with a 6200 RPM shift point.

I think that I am getting some valve float now at over 6000 rpm. The motor used to produce peak power at about 6350rpm, now I am seeing my peak as soon as 5600 or so, and it falls off at 6k+.

The valve springs, and AFR hydra rev kit now have 60k miles on them, so I think they have seen better days.

I definately would not say the heads are the weak link here. 388rwhp/381rwtq is nothing to sneeze at.

Thanks for chiming in Lloyd. I will give you a quick run down of my combo starting from the CAI to the tail pipes:

RK sport Honker CAI
NO MAF (Accel DFI)
Trickflow Intake elbow
BBK 58mm TB
Ported LT4 Intake
COMP 1.6 Magnum rockers
MMS Aggressor series heads
AFR Hydra Rev kit
STOCK SHORT BLOCK(126k miles)
CC306 cam
MSD 6A ignition + coil
Alum. Radiator
Pacesetter 1 3/4 longtubes
No cats
Borla Catback
Fresh T56
3.73's

I HAVE NOT ADJUSTED THE VALVES since I've had the car (3.5 yrs) and doubt they were adjusted since the last tune in 2000.

Here is a link to a run down and comparison of my last dyno (MMS tune the way I bought it) and a recent dyno with a few upgrades and a tune by Harv St. Mary: https://ls1tech.com/forums/dynamometer-results-comparisons/643900-re-tuned-lt1-today.html

I think the car is producing great torque down low for a CC306, I just wish I could get some more peak hp out of it up top. I picked up 10rwhp at 5500rpm from the tune, but the car falls on its face at 6k+.

Let me know what you think.

My buddy just bought a 94Z28 yesterday, so I may just sell him my setup to buy your LE3 combo, we'll see.

Anyone want to host these scanned graphs for me? I can't attach them, they are too large, even when resized and saved at lowest quality.

Some one help me out please.
