Time For Different Set Up

[Coff 06]

If you don't optimize the compression for the cam you already have.
You'll never have any idea of the potential that's in there waiting to come out.
Change the whole setup and you could be right back here trying to get more out of it.

Tomorrow I will finally be able to do the compression test. I'll post what I find.

Whatever came of this? That said, the Tman 590s are a great combination of low end torque that runs runs out to redline. 127/126 in my 107 and that's with true duals. I just saw a dyno sheet someone sent me of 129/128 with a fatcat in a 107 .110ft.lbs. torque @ 2200 rpm.
Jason @ C&S Speedshop tuned a 110 doing  132HP/128Torque with the 590s with stock 110 heads.
Agree your heads are holding you back tho.

I haven't gotten to taking the test yet. Hopefully later today or tomorrow. I need to pick up a remote starter switch first.

Agreed on the heads. I'm favoring more and more to shave the heads that I have on down. Will cost me less.

[60Gunner]

Good place to start.  You want at least 200psi ccp.
My CCP is 212 and my heads flow 310+cfm @ .700 lift with an average in the 230s cfm. 305+ @ .600 lift.
What I like is the 590s do what they do @ .590 lift. Easy on the valve train. My spring seat pressure is 147. 347 open.

I'm going to keep the cam that I have for now. After this project gets done I will be at around 11.8:1 static.

I'm well aware of that. That's why I asked your current cam specs and compression. You can pull the heads and shave them to get the compression you need for you current cams assuming you don't run into any clearance issues.
Without knowing TDC lift of your cams and how much needs to come off...?

Or swap cams based on your current compression/configuration.
A 117 at 10.8 did 132hp/140 torque. 120+ torque at 2000rpm. 55mm throttle body and 4.9 injectors. A 124 even better. Couldn't find the dyno on the 124 at the moment. Both 590s. They can be run from 10.5 to 11.1.
I did find a turbo'd 124 with them doing 232/201. : )

Just throwing out the other alternative depending on current compression. Swapping  cams is way easier imo. Especially one known to do what you want with your current configuration.

Good luck.

The cam is less than .200 for TDC lift. The cam is a .585 lift I, .601 lift E, IVC is 56, Durations are 255/260, overlap 60°, LSA 109° As I have been saying, when this engine was built, it was intended for higher interstate speed travel. Currently I'm in the 9.4:1 corrected compression range. I want to buy this up to about 9.8-9.9 range. Before I make final decision, piston to valve clearance will be checked to see if I can do what I want.

[harpwrench]

Have you looked at cyclerama's 630i?
What pipe are you running?

Here's a link to a 124 that might be similar to yours, with the 630i and stage I 110 heads (I believe the tuner told me they still had stock intake valves)

I have considered it but I think the reason why I said no to it was I could never find the full cam specs. Mr Don has suggested this cam. If this cam is really close to their 630, I'm leary of the TDC lift because my pistons are proud of the deck.

[Ohio HD]

I don't think that CR has a 630 any longer, only the 630i. As far as specs, they're all over the internet, and also here.

As far as TDC lift, 0.210" isn't all that aggressive. Most aftermarket pistons have larger than OEM valve reliefs. Until you clay what you have now, or use the drop valve method, you can't make a decision as to what will work. Clay is a better method in my opinion.

Thanks. First time I have seen the complete specs. I forgot to mention that the cams specs I gave were measured from @ 0.50 not .053.

To be honest, if I were to change cams, I would prefer an lsa of 105-106.


Added: Also not seeing the 630I available for 99-06 gear drive.

[Ohio HD]

If you copied a Lunati cam that closes at 51° it would be one of these.

I agree.  Clay is the way to go.  Choose the cam because it has the right properties you are looking for (confirm on dyno sheets), Mock up the engine and use clay, measure all of the relevant clearances and if necessary have the valve pockets touched up.  As you can see the eyebrow and the depth are visible to the eye also. The eyebrow can be a concern with cut heads (for compression), thinner gaskets and larger valves when using some pistons.  Mocking up the engine before assembly doesn't take long and tends to increase your confidence and comfort when it goes back together for real.

If your pistons are actually out of the hole a few thousand consider a thicker base gasket that will remedy that.   Cometic will make them for you if they have the right stock.  There are a few ways to accomplish it.

Mr. Don is a fan of the Dave Mackie 598. I know of several 124s running them. Two or three in same thread on another forum. 143/144 with R&R billet heads.
You'll get better low end torque with the tman 590s tho I think.
DM598 comes gear drive too. 254/256 duration. 44° overlap. LSA 105.5

This is an interesting cam. 🤔

[tdrglide]

If you're looking at the Mackie 598,
Mackie shows the 598 needs 10.2+cr. He's being way conservative. It would be very soft on bottom at that cr.
I have ran it at 11 to 11.1. That is where it really shines. Also very quiet and no need for roller rockers. Excellent long distance touring with power

This cam is very interesting indeed. I know Mr. Don loves this cam. We talked about it when I did my my build. Actually right after. I might've done it myself had I not already had the 590s.
The Tman 590PS2 or this DM598  at 10.8 - 11.0 are 2 very good cams for what you want. The 590 will have a little more cranking compression at the same compression ratio. About 8-10psi more as I recall.
These would be my choices and hard to beat for cams with good low end torque that run out to 6000rpm for good top end too. And easy on the valve train!

205-210 ccp is good for me. Do you work for TMan? Pushing that 590 pretty hard. Lol No worries, it's all good. Gosh, I would think that at 10;1 Corrected that that plenty of squeeze.

Nope, I just know what they're capable of. So does Don. So does my tuner you all know here. He's already told you the same thing hasn't he? For some reason you don't seem to want to listen or care for them. Not sure which.
Either of these two cams are great for what you want. Yes in a 124. And they won't beat the snot out of your valvevtrain doing it. That's why I like them.

Look at the woods 888 once. Tell me what you see?

Who is Mr. Don?

Head Porter.

The CR630i is a good cam too if you have the clearance. Higher lift, require higher spring pressures probably and roller rockers?

Who is Mr. Don?

Dorfman, you guys are referring to him as Mr. Don? blahahahahha

I assume that's who he was referring to in a post a ways back. Just kind of stuck.  lol
