With MM depending on how we set the car up I leave between 4400 RPM to 6000 RPM off of the trans brake. 
Way back when it was a stick I used to pop or side step the clutch between 7000 and 7500 RPM.  But that was nothing.........  Way back when I had my 68 351C powered coupe we thought that all 351C's had to be run like Pro Stocks.
Backed up by a 48 lb flywheel and a DNE 3.25 low gear 5 speed I used to launch that roller cammed, tunnel rammed bad *** Cleveland at 9500 RPM by side stepping the clutch. (double lol)
After several consecutive weeks of lost bearings and valve springs it finaly expired going through the lights one day at Oswego Dragstrip. 
That's when I decided to build the 404 inch Cleveland with the G&R heads, but that's another story. So....what's the highest you have launched your stuff? ------------------

When I was running a top loader and a hydralic cammed cleveland, I was launching at 6000rpm. I only broke one drive shaft. It was a blast! ------------------

That 68 of mine was a Lakewood "Pro/Stock" style "J" bolt hopper bar car with 5.67 gears and 10.5 x 28.5 M&H 330 compound tires.
It had Carrera shocks on the front and Monroe Drag Levelers on the rear. (anyone remember those?)
We used to do 4 or 5 "dry hops" in those days after the wet burnout and it would jerk the front end up about 3 feet on the last one. Boy that used to be fun racing. ------------------

I once made it too 2000rpm. 
Ok now you can all make fun of me.9500RPM what feeling that would have been. "Boy that used to be fun racing" and it still should be fun.  SCOOP ------------------

The engine gets shifted at 6800 rpm...Off the bottle, it gets launched at 7000 rpm WFO off the 2-step. Launching with the bottle ON it gets toned down a bit by launching at only 6000 rpm. The trans is a STOCK small input, wide ratio (2.78 first gear) toploader... running to a 4.33 'N' case detroit locker and 31 spline axles spinning 28x9 Hoosier slicks.With a good track, it can 60ft as well as 1.43 seconds on the bottle. It bogs off the bottle to mid 1.6 60fts about every time. The car is MAJOR fun to drive. I launch it WFO regardless of track condition.... cause I can, and it's more fun that way! There were quite a few parts broken finding the weakest links, but all is good now. Nothing has broken for a long time. Good Luck! ------------------

My old C/SM 66 Modified Production car with a Boss 294 Destroker did not even leave as high as the 351C. With one 750 DP carb it did not rev as freely to 9500 as the tunnel ram combo.I would leave and shift that car at 9000 RPM with a Liberty 2.88 low Top Loader. ------------------

Lessons learned...You can beat the CRAP out of a car with radials, but you won't really test the driveline until a sticky set of slicks is bolted on and the car is taken to a sticky dragstrip! Don't make too many back to back runs with an organic clutch launching WFO. They get too hot and the facing comes off. Been there, done that. (without a rev limiter) Bent all eight exhaust valves as the engine hit a bazillion rpm. After the repair was made, I bought a (then new to the market) MSD 6AL with rev limiter. A 2-step came later, and made launching the stick shift WFO HUGE fun! 2-pinion trac-locs will NOT hold up to WFO launches with slicks. 28 spline axles will NOT hold up to WFO launches with slicks. Standard 9" center section housings will NOT hold up to WFO launches with slicks.
The rear caps (while remaining bolted in place) get their centers blown out and the ring gear puts a series of dents into the back of the housing. Aftermarket unit is HIGHLY recommended. Daytona pinion supports are also a smart way to spend a $100 bill. Do NOT use homemade 31 spline axles. You can make them for a 66 mustang by cutting and resplining one side. (works okay, but the splines were twisting) ...and machining the HUB side of the other side. The hub will break off, and the whole wheel will become detached! Luckily I was using a spool, and launching WFO on the bottle, so the car spun around when the wheel came off on the starting line and the quarter panel did not land on the tire. But the car ran over the timing components and a downpour of rain immedietly started. Factory 28 spline slipyokes will NOT hold up to WFO launches on slicks. The splines will twist, and they will become stuck on the the mainshaft and vibrate like h*ll. You've got to get some speed up... let the engine idle with the clutch in, then sidestep it to pop the slipyoke loose. After ruining several, I finally found out Mark Williams Engineering makes a NICE aftermarket unit that will hold up to about anything. It cost around $170 at the time and uses a #1350 1-ton truck u-joint, (new driveshaft needed made) but it solved all problems! Do NOT use a bronze faced paddle clutch! These things are VERY aggressive and are either ON or OFF. They are like a d*mn coupler. There is ZERO slip with these and they BREAK PARTS! Sintered iron (slipper) racing units are WAY easier on the driveline... and more streetable to boot! Do NOT run tubes on the street with a spool. They will get pinched and leak... and cause you to spend your time figuring a way to get your car home. Well, that should be enough for now... Good Luck!

That's why they call them 'cleaning ladies' They'll clean out your entire drivetrain.

I used a rag Weber race disc clutch in the 351C and a 4 paddle sintered iron Ram in the Boss 294 de-stroker. The Boss deal had an aluminum flywheel. ------------------

Yep, they are still proud of them. They must be, I bought one this year and had to pay $182 for it. But it is a very nice piece.
Something I learned, stock driveshafts dont like low 1.30 60' times in a 2800 lb car either. I have one at my dad's that is now a multi-piece shaft.

5500 in the 68 Stang....
btw; I?m not a Chevy guy by any stretch of the imagination, but years ago there was a black Monza at our track that sounded like it was leaving at 12K+... never did see it make a full pass, couldn?t hold the drive shaft in long enough to make a full pass, lol. Sure did sound good though.

In the Midwest there is a group called the Ozark Mountain Super Shifters. Thet get appearance money and travel a circuit.These fellas are the kings of high RPM launches. One of them is a regular at Eddyville with a Camaro of late 70s vintage, I think. They all look alike to me This guy has toned it down a bit, but a few years ago he had a destroked smallblock. He claimed to be launching at 10,600 and shifting at 9800. I can tell you,it sounded like every bit of that. Soembody told me they were changing valve springs every week. Them stickshift guys are kinda like motorcycle racers. Got some crossed up wiring somewhere.

I am set up to leave at 5800 & do the rowing at 7400. Way back when I ran a small block it was pretty much matted when I dumped the clutch. Had one of those old cable tacks with a tell tail & it bumped 9800 on the gear changes. I shifted then when it felt like it was nosing over.

Partially true Mike: Like the Cintered Iron clutch they need to be adjusted down to where the clutch is on the verge of slipping an then tightened back up 1/4 turn at a time. Both will break parts if not adjusted correctly, I have the third member and trans gears to prove it. So far the only advantage to Cintered Iron is that if you slip the clutch too much you can tighten it up and it will come back; the bronze disk will need to be redone or replaced.

Damn rev limiters anyways.... they have kept me from launching any higher than 7000 in my Fairlane and 6000 in my stupid Ranger.Without a rev limiter (or a tow truck) i've launched my ramptruck at 5000 a few times poor thing.

Dick Weinly ( sorry if I misspelled your name Dick ) the owner of Edgewater Park raceway in Cin. found a rare Mopar/Weslake Indy motor from the early seventies and put it in a Challenger for M/P or gas class. At 277cu.in. it wanted to rev so he obliged. By the third amber it was WFO and howling like a banshee. Unfortunately it was broken more than it ran. Stone Woods and Cook showed up with a 65 Mustang AA/GS with the Chrysler Hemi and attempted a bonsai launch against Ohio George one night. They promptly dropped the bottom out of the motor all over the starting line. Souvenier seekers had most of the parts gone B4 the cleanup crew could assess the damage!
