Come on guys I'm tearing my hair out reading all these cam threads and visiting supplier websites.

Comp cams software says 216/220 114 is my best fit
Lunati told me 217/223 113 is best
Patrick G in a current thread wrote 217/221 112 is best for mid rpm torque (OK maybe I'm seeing a trend here)

How many variables can there be for a full bolt-on DD cam only mod?!? ('02 Z28 M6 4.11 241 heads, LTs, 10.1 compression etc etc...)

When I say DD, I mean I shift around 3000-3500 rpm 90% of the time, not 6500. So low to mid-band is where I want my throttle response & torque.

I really don't know how to make this decision. Most everyone swears by their cam, yet their specs are all over the board for the same bolt-ons.

The light has definately NOT come on yet!

Thanks for letting a non-mechanic vent!

There are as many variables as you want their to be. Any of the cams you mentioned will work. Try all three and then you will know for sure. ha ha. I just built a an ls2 with ls3 heads and intake. It is in a 4,000 lb pickup. I had a 224/224 cam laying around that I bought here on the forum. The truck has about 50 hp more than I expected and idles and drives great. My point is "their is not an exact cam for your engine" It is someones educated estimate and everyone has a slightly different opinion. You have to pick someone you trust and go with their "estimate".

To tell you the truth man those cams aren't all that different. There's no point in stressing over it. I highly doubt you would be able to even notice a difference between those 3 cams. You'll be happy with the power gained with any of those cam swaps and since you're not out to set any records, just choose one and never look back.

Until you want more power that is lol which you probably eventually when choosing a cam that small.

Add these EPS cams to your list.

ASA cam comes into mind when you want a good low end torque to mid.

Here is one w/ .525 lift 226 degree intake/ 236 exht.

Thanks guys for your feedback
I'll take a look at the other cams you mentioned. But, at this point I think I'll just shift focus to who has the best package deal (springs pushrods etc).

Thanks

The 224r from Texas-speed is great if you want a good mid range .

Like Chuck said, the differences in those cams is very minimal. Unless those are the only cams you are looking at I would recommend a 224/228. This cam is a proven DD cam that still has the potential to make very good power.

i would go with the 230/224 cam from thunder racing over that 224/230. its a good solid street cam that performs and lopes very sick. If you go with the 224/230 you will want to go bigger.

yeahh driveability will be there too more so than the standard split cam. Stock heads, reverse split. Aftermarket heads or ported, standard split

garygnu

get the EPS cams,or a tr224 .

i was running a tr220 cam before i put in my new one. Had great low end and midrange. Plus had no driveability issues.. been considering selling it..

Paul 1953

I told my wife it was all settled. I finally decided. Based on all the testimonies, I was going to get SDPD LS1 Hot Cam package. $475.

Mean lopey sound, drivability, easy on the springs, though modest power gains.

Then... I started thinking about the magical, elusive 400 rwhp... and I was back to the beginning all over again dazed n confused.

Heck, so what if the power peaks up where I don't use it at 6K? It always peaks up there. But so long as the torque curve is flat from 2500. That's what I'm after. (plus bragging rights for the 400hp)

So, as so many keep saying. I will call Geoff at EPS in the morning.

A cam that breaks 400-410whp isn't going to have max spring life, drivability, and low rpm torque.

A 228/232 113 should daily drive very well with a reputable tuner and still have real good low end torque but also be very close to that 400rwhp mark. You're going to have to raise that 6000rpm redline though to about 6500rpm

If you want to stay with the stock 6000rpm redline consider the tr224 112lsa but with the 112lsa will make for a rough idle if you think that isn't acceptable for a DD. I would just get the cam at the top PatG recommended on a 113lsa and it should be everything you want besides able to break 400rwhp, might be around 370rwhp.

If you want a DD and over 400rwhp like I wanted you could just pick up a mild cam and some heads.

You are smart to just call Geoff....Let us know what he specs...

Paul 1953

So yes...thanks everyone.
Just to close out this thread. I had a great informative talk with Geoff.

Hahahaha First question he asked was "How old are you?"
Turns out there are different cams for 20 yr olds and 57 yr olds like me ;-)

He gave me a nice package deal with his recommended 222/226 113 (+beehive springs, 7.425 p-rods, timing chain & gaskets).

Between that and the MGW shifter arriving any day, it should feel like a new car!

I'll post results later on.

iTrader: (16)

LOL. That's what I have. I put it in with a set of stock 243 heads though.

SOMbitch

iTrader: (8)

yeah your cam has -2* overlap at .050. The 20 year olds get a prescription for + overlap haha...

Paul 1953

I forgot to say, that Geoff's best guess, based on a '98 vette (LS1 + LS6 intake) with this cam and same boltons would net me about 50ft/lbs gain across the band and around 380rwhp with a good tune.
We'll see. We are still waiting for Bene's numbers.

Dyno numbers are in however the way the tuner set up his dyno dynamics dyno machine, it's pretty screwed up numbers. He also tuned my car rich from mid range to 6K rpm. AFR was 12 to 11.7 all the way to the top end.

I'm getting it retuned though.

The car pulls pretty hard and idles great.

You are probably in better position as you will have many choices to who to tune your car and many dyno shop to find out your numbers. Me, well I probably have only this tuner.
