all I can say is that what I am hearing is not sounding too comforting, although I still dont have a ballpark idea of how much they can take 
Why don't you spray it and tell us? None of the guys above have said they are on the juice so their stories only partly help, your clutch may or may not, I'll eer on the side of not, handle the hit of spray so the trans will hold up just fine I would think ...
Buy a couple of spare transmissions and clutches and take them to the track with you . 
Car runs 11.80's now, is sooo close to breakin into the .70's when I get the chassis completely sorted out...I want to hit it atleast with a 100 shot, and work up to a 175-200 hit- Thats what im worried about with the 23 spline, is the hits on the spray
Im too poor to be a guinea pig lol...I'd rather be able to get rid of both transmission while they are still in working condition and worth something to upgrade to whatever else I choose then sell them with broken parts

There ya have a fine thought. Ive often thought of pulling my set up, which is basically like new, all rebuilt trnny, newer clutch, blowproof bell, billet flywheel, HD rods, and sell it for a good amount down on a 5 speed set up. BUT like ya said being low on coin and having to sell stuff for the parts sucks really bad.

When I called Liberty, a set of cryo'd Korean 18 spline gears was around $1100.00, if I had the extra coin, I would have them.
Haven't heard much good about those gears in the past...what did Liberty have to say about them???

hi, I ran the 23 spline slick shifted with synthetic gear oil for years. only problem was 3 rd gear, broke 2 of them. I ran it from 1977 to 2009, replaced it with a jerico. the car is a NHRA stocker 340 duster. jerico will save you money and time. they will bolt up to your bellhousing.
How fast was the car running? And at what weight? Did it have an adjustable clutch?
I always thought a Jerico would require a bellhousing swap, not to mention they are some serious coin even used

That serious coin depends on how you look at it. I wasted some serious coin by paying Liberty to go though my tranny and slick shift as well. I got 9 passes out of that investment, some pretty expensive trips down the track. That money would have paid for about half of my Jerico, money much better spent.
You don't need to do a bellhousing swap if you already have a Lakewood, you just need to re-drill it for the Jerico

Matt, be aware that if you remove the 4 speed you will be required to pm me your address so I can send a couple skirts your way...  I went through 2 of the Korean gear sets in my 18 splines, both kryo'd and mikronited. Both broke, 3rd, at about 35-36 passes in a 3300lb a body running 10.40's. That was with an adjustable clutch. The clutch change helped prolong stuff until the trans upgrade. I'm on year 6 of the adjustable clutch and still no racepak or anything. Am I leaving something on the table? Probably but I don't run class stuff so if I was that concerned with a couple hundreths I'd put myself on a diet. Good luck.

I just might have to pm you then lol...I have been looking since early summer for a used Jerico/G-Force for a good deal, but nothing that I have been able to swing the cash for. Its strictly coming down to a cash game for me right now. Im going to still look into the winter, but if nothing, an auto will probably be finding its way into the car 
Good to know though that those Korean gearsets aren't the bees knees. Ditto on the racepak, I think I could get away without one as well if I go the adjustable route
