I like those numbers as well!!!

I guess you probably did have a great time during the dyno session, hmmmm a fun thing to do.

Great numbers... and ditto on all what Robs says. Especially the muffler thing!

A few thoughts...

First off, those are really good numbers! Has anything been done to the engine? Any idea what cam?

That HP peak sounds about right for an LS-6 through manifolds. Mine peaked at 5400, and somewhere earlier in the thread I think someone posted that's about the neighborhood it's supposed to be in. An L-72 peaks about 300-500 higher due to it's shorter stroke, but doesn't make near the torque the LS-6 does.

As for mufflers, skip the Flowmasters and go with the Dynomax units. I've got the part number around here somewhere, but they make an AWESOME muffler for the A-bodies that will outflow that Flowmaster and will sound TONS better as well. It's what I've run on my L-78 and my LS-6, and is what the majority of the Pure Stock guys run. If I can find it, I've got an unbelievable exhaust test done by the Buick club that raves about this muffler...

You are correct in thinking all the little things (carb, valve job, etc.) will help, as it all adds up. Be careful and get the original type Pertronix unit and not the later model. Trust me, you don't want the newer style.

Again, AWESOME numbers, and I'd love to see what that thing would do on the track!

<font color="blue"> Rob,

Any info that you can send on the Dynomax mufflers would be great. I had Flowmasters on my '70 SS396 and was very happy with the results. If you have had BETTER results with the Dynomax, I am all for it. How loud is the resonation inside the car? I ask this because my LS6 is a 4.10 Posi M22 car, and at 60 it's plenty loud already. As for the Pertronix, I used the older style on the SS396 and was very happy with the results. I had heard the scuttlebut about the newer model. If you could dig out the info on that Buick test, that would be great. What size pipes did you run with the dynomax mufflers?

Thanks for the commentary and tips, I appreciate it. </font>

<font color="blue"> To my understanding, Cam, carb and heads are BASICALLY stock. The original owner messed around with valves back in 1971-1973, but he cannot recall what he ultimately did. Otherwise it's stock Chevrolet under the hood. If you look at the pics on my link below, you can see it's all original, except for new plugs, rotor, points, and plug wires. Even the valve covers (oxidation and all) appear original. </font>

Re: Running on the Dyno with my LS6 on Friday
 

Very good numbers. The Moroso power calculator says the car would run 12.50's with good 60 foot times. I'm assuming it weights 3900lbs with driver.

I think the DynoMax Ultra Flo SS would be the 17288's or the 17289's. I would tell you to go to the Pure Stock Drags so you could listen to them on the cars. It will save you money if you're really picky about how they sound.

Re: Running on the Dyno with my LS6 on Friday
 

What kind of advance curve and jetting seems to work best for you guys?

Rob,

I'm also interested in this info (Dynomax part numbers and Buick test) if you can find it. [img]/ubbthreads/images/graemlins/beers.gif[/img]

Re: Running on the Dyno with my LS6 on Friday
 

JLerum... Can you tell me what the Moroso Calculator says about my ZL1 Clone ? It made 828 rwhp and 823 Ft lbs...

Re: Running on the Dyno with my LS6 on Friday
 

Charley,

I need to know what your weight of the car is.

4000lbs-9.65@138
3900lbs-9.58@140
[email protected]
3700LBS-9.42@143
3600LBS-9.35@144
[email protected]

How does that sound to you????????

Re: Running on the Dyno with my LS6 on Friday
 

Hey Charley, do you still have that car?

Re: Running on the Dyno with my LS6 on Friday
 

I have no idea what it Weighs. It is a 69 RS SS Camaro with a Aluminum 540" Engine with a Procharger. It has a lighter Wayne Due Subframe. I would think it would be a little lighter than a RS SS 396 69 Camaro. Yes I still have it and yes it is still For Sale.

Charley,
Maybe TWA would be interested--Domestic flights of course. [img]/ubbthreads/images/graemlins/cool.gif[/img]

Dennis, is your car a turbo 400 or an M22?

Re: Running on the Dyno with my LS6 on Friday
 

Morris,
Glad to see/hear you are ringing her out. There is plenty more where that came form. A carb rework/tune, distributor recurve and some other small fixes and you'll be into the 400's. Very nice numbers. [img]/ubbthreads/images/graemlins/biggthumpup.gif[/img]

Re: Running on the Dyno with my LS6 on Friday
 

M-40 with 4:10's. Mr. 70 will tell you I'm too old to handle an M-22! [img]/ubbthreads/images/graemlins/no.gif[/img] [img]/ubbthreads/images/graemlins/3gears.gif[/img] [img]/ubbthreads/images/graemlins/3gears.gif[/img] [img]/ubbthreads/images/graemlins/3gears.gif[/img]

<font color="blue"> Thanks Rick, good to hear from you. Car did great, although there was a lot more I suspect. Even the dyno guy took a pull, and he said it felt super strong. It's amazing how flat the torque curve was on the graph. </font>

<font color="blue"> Dennis, I remember reading about you and your car in Chevy Rumble. I don't get it....you sprung for the M40 and power steering, but wouldn't get the Cowl Induction...what kind of drag racer are you??

A damned poor one; by any definition! Actually, I ordered the car without PS but "Sly Ol' Fox" threw it on the spec sheet for some reason. Still a thorn in my side, the belt likes to depart around 6K!

When I ordered this car I was working for the Highway Dept. for about $3/hr; living in a trailer in my In-law's back yard. A year and a half later we parked the Chevelle and bought a '68 427 Corvette. (It was a 4 speed, and Yes, we were still in the trailer! I had my priorities straight even back then.) I knew I wanted the LS-6 powerplant and since the $ were short, I was willing to give up all the bells and whistles to get it. No CI, no buckets, no gauge pkg, no clock, etc. Aside from the PS, I'd do the same thing again. The CY M-40 is a hell of a tranny but I might opt for the M-22 this time.

Re: Running on the Dyno with my LS6 on Friday
 

Guys, if I get a second tomorrow, uh, I mean "today", I'll see if I can dig up the article and the part #. No promises, as it's after 2am now, and we still have to finish buttoning up the L-72 in the Camaro, load, mount some tires....

But, if I don't get to it today, I'll do it first thing after the Reunion.

<font color="blue"> Again Dennis, cool story, just having some fun with you...glad to see you've hung onto the car all these years. How many years was the LS6 parked? BTW, the power steering may be a hinderance on the track, but it makes driving the car in and out of the garage a chore. Love the black, by the way. </font>
