Im guessing this list is just for current setups as I know LG / Cartek / and a couple of others that dropped 500+ with 346`s many times several years ago. Im sure a quick search would fill in a bunch of those boxes if ya wanted

Wheel hp is hard to messure through a big stalled auto.. Besides some of the engines in question were built for peak #'s but may not run the #'s. Just saying..

If you have a link that still works with set up information. I can post those. Certainly applies here.

Do you mean at the engine? Power at the wheels is power at the wheels. The glides just keep it in the best Rpm range at all times. (advantage over frictional loss through trans) Is the power at the wheels different at the track than at the dyno? (more load sort of thing?) I'm truly asking to learn, not being sarcastic.

Some big numbers. This is what I was looking forward to. More than I thought so soon though. I will correct / add some numbers on the first page tonight. I might have to go to the top 15 (instead of 10) to let some mostly street guys play too.

No we didnt make any threads. I rarely make threads about builds any more... Dont have much time.

We made:
~718rwhp(dynojet est.) with a 388ci motor thru 4.10 gears and a manual.
~530rwhp(dynojet est.) with a 346ci motor thru 4.10 gears and a manual.

I'm down for some dyno racing. Mine made 714 on the engine dyno at 416ci (1.71 hp/ci). The build thread and dyno sheets are linked in my signature.


I've got a bit more in this car when I can finally get some fuel in it (see 14-15:1afr) and work on the 60ft times. Running down the track seems to take far more work than the dyno!

I would love for you to quantify this statement. Please tell us how a 2 speed trans helps to keep the motor in it's best RPM range at all times, vs a 4 speed auto or even 6 speed auto.



I also think that for the auto stuff, the trans type and locked/unlocked should be mentioned. Some guys only dyno their 4L60's/4L80's unlocked and some only dyno them locked. TH350's/400's/glides can't be locked.

In the US, we measure power by mph at the track

That Hp/liter is too foreign to us and soo

I apologize. I admit to not being an expert in these transmissions and don't mean to offend. I'm sure theres some heavy debate or argument for either somewhere on here that I could learn more?

I will mention it in the list if it is in their description. But, why would someone not lock their trans when on the dyno?

Yep. I knew this comment was coming. I pretty much made an American version of HP/Liter. Difference is, in this set up, if you can make that much HP/liter with a smaller cubic inch, it should work out to the same or better with the larger. - Same architecture, bigger valves allows bigger flow, etc.

MPH at the the track measures WAY more than just an engines capabilities. E.T. of course is the major player in set up and driver. But E.T's give way to how much tire stick, how well you shift if in a manual, etc. The purpose here is to keep it as engine only as possible. Which is also impossible because of friction losses in the transmissions and what accessories are attached, and of what style, and the endless combinations in between. BUT. You have to start somewhere.

I made 573/530rw SAE at 5 on a DJ out of a DD 416 in my C5 Z. The stat's, graphs, and track vids are on here if you search my name.

Not my car. One of about a dozen aggressive C6 Z06's around here from a local shop. If I ever see him at a gathering I'll ask for a dyno sheet or have him post up about it.

Unfair comparisons. It's impossible to factor in the differences between transmissions, rears, rotating assembly weight and other rotating mass.

Some fear that the converter can't hold the power under lock-up.

Others feel that numbers locked are inflated as most people don't lock the verter but the top of third. In other words, you are not using all the power.


My little 347ci motor I built made 449rwhp through an 80e locked up. No doubt in my mind it would have shown more power through a 60e locked.

My current 418ci motor made 521rwhp through the same 80e locked up.

Both were on running 91 octane.

LOL at the *notes.... Then the autos ******* dominate.

There was a black camaro 346 (similar to what DMmizzel has) auto that put down like 44X? or so. No idea where to find it now.

Please post a dyno sheet and a link to the build. I will post.


Uh Huh.. The guys with the autos are making more total power at the engine. The reason there are so many autos that are kicking *** is that is where full on drag race motors reside. Put a standard on those engines that can handle that power and watch the power numbers grow larger than what the auto numbers are showing. That was the nature of the *note. - on the flip side, some might not look so sweet at the very low end of the revs, but there is no need for power down there with the drag racing dedicated autos.

None the less. You can still learn much. If you see a big power motor that STARTS it's dyno @6K rpm and goes to 9500, there is no need to compare your weekend warrior six speed to it. Trust me, you're most likely not going to pull up next to it at a stop light. (it happens though)

then... unlocked is all they have to show and that's all that can be told. The only "fair" answer I have for them is that I will post locked or unlocked if it is mentioned.

I'm not sure what you're trying to say here. But in general I think I know what you are saying. Thank you for the reply.

I guess I could put that up. Good to know whats out there. It's funny how high the rpms are when the dyno STARTS. Does any one individual own it?

Here are two like the first one. Now that I'm reading these, I'm not sure this is really what I had in mind for this list. I'll think it over. Maybe hear some opinions? Full Vendor builds? I think they deserve their own lists. This list is more for a private party sort of thing.

I can do the search, but if everyone said,"just search my name" I wouldn't. I just did a search for you and the damn search froze. Not kidding. tried 3xs. Please post a link and I will post.


I am trying to cover this statement. You're about the 3rd to say it so far. - he who only read the first few posts and then posted the above..... Please read the other posts and you will find a few others already covered this and my reply.

There will never be a perfect comparison. Please just make the best of it.
