Jim Woods knows my engine well,probaly has my specs memorized LOL

The best way is take your car apart @ home,have head,intake etc. clean ready to go back together,I always set head,intake,bolts,pushrods rockers etc., all back in place @ home basically put all back together and just start bolts,that way you don't get to track putting back together and find out you left something @ home.
Show up on first day of pro am Friday of Sat. and Sun races,I always call the tech man and see when is good time to be there.
Since yours has'nt been apart this would really be good ideal, in case you have broken bolts or anything else that might need fixed. Measure head diameter of valves,they get bigger after miles,will flatten out 45 and make burr,best description around valve and cause head to measure big.
LT won't be too bad to put back,lot easier than LS,I know guys take heads off LS in the car,but I believe I would just as soon drop engine out bottom, I had to put water plug in pass head of my sons I left out ,I thought I was going to have to drop engine back out to get it in there, finally got it though.

Great advice rt there! Thanks! I was mainly afraid to pull it apart at IRR since I still have the stock exhaust manifolds on it. I just KNOW those will be a B!#$%. Headers to be installed soon. I ran it at Palm Beach last night. Got some decent rear shocks since the converter showed me how bad the 158k old ones were. Night and day! LOL! It actually pulls a baby wheelie and the shorties fell from 1.72 to a new best of 1.68. Now if I can just get it to shift waayyy sooner(next project).

Kenny:
Are you running ODB1 or ODB 2?
Have TunerCat for ODB1 on my Laptop,

Bryan Herter can get you a tune that is damn near perfect.
Who built your 4L60E?

Also installing a YankPT4200 Converter replacing my YankSS3800.
Hope to see a bit of improvement.

Hey Dan, I'm running OBD1 and its a completely stock 158k 4L60 (no E). Wish I had done some homework as a 4L60E and OBD2 car would have been much more desirable. I probably still would have bought my 93 just cause it was a good deal. I'm waiting still on headers, need to get a chip burnt, and mainly need to get the tranny to shift earlier and more consistently. Got a trans-pak kit that is supposed to make the valve body manual and I would like to tweak the governor a lil to be able to leave it in D for bracket racing. My converter is a 4k stall and with the LOW first gear and 4.10's I feel like a lil tighter might be better. How does the tuner cats deal work? Do you burn your own chips?

ODB1 you program the PCM.
Bit easier to program than ODB2
Is your converter a locking converter?
Amazing you have a 4k stall converter without the ODB1 1-2 Shift fix.

BTW Bullet Cams has the perfect Legal Pure Stock Blueprint Cam and Springs for your car.

I'll have to do some homework on the Tunercats deal. I will get a chip from someone after making the final major changes but it would be nice to be able to tweak it in the future. I called Greg at FTI about a converter. He has done several converters for me in the past. When I told him about this project I could almost see the gleam in his eye over the phone. Its a non-lockup (made the changes to the tranny) 4k street fighter series. Plus I COULD NOT beat the price. Less than I found most used converters. 60' went from 1.92 to 1.68!!!!! Please tell me about the 1-2 shift fix on a non-E tranny. I just got a B&M Trans Pak and hope that helps but if there is something else I would forever be in your debt! LOL!

PS. Bullet will be getting a phone call down the road.

Do you have a 93 or 95 LT1 Camaro?
The Manual Valve Body most likely by passed the 1-2 Shift Issue.

Using a Converter greater than 3000 Stall causes the Housing to twist a degree or two preventing the Reluctor to lose signal with the Pickup.
Happens with Slicks and grippy surface.
Under normal conditions and street tires you do not have that problem.

Not an issue with ODB2.

BTW 4200 Stall is about the limit on our engines.

He evidently has a '93 if it came with a 4L60 (not an E ), which has no shift issues with what guys call the "stall wall". That is only an issue with the '94/'95 LT1 PCMs. Had zero to do with the tail housing. It's a slip test issue in the '94/'95 PCM. I have a software hack for that. The OBD2 boxes happen to not have that. It has nothing to do with OBD1 or 2.
The '93 required a device programmer (aka "chip burner") and eraser if normal EPROMs are used. Also a couple of EPROMs and a piggy- back board, or spare factory MEMCALs with EPROMs which GM stopped selling in 2007. Some of the later MEMCALs came with OTP (One Time Programmable) proms. Saved GM about $.75 per unit.
Not sure where the 4200 stall limit story came from? Guys are running higher than that.

[KennyAnderson]

This is a 93 with OBD1 and a no E 4L60. The tranny has no electronic controls. It uses a governor like a TH350 etc. I'm hoping the manual VB feature of this shift kit fixes it. I like the idea of leaving it in drive but it seems to shift inconsistently and late. The reason I say this converter could be tighter is simply cause with the 3 sumptin low gear and 4.10's it really revs fast in 1st and goes thru the power band quick. I'm seat of the pants guessing but the power band seems to be around 4500-5500.

Got headers today too! Woohoo! Long story short, I'm whittling away at it and the car responded a ton to everything I've done. .5 under shouldnt be much trouble.

[Ed Wright]

If the rules allowed a different ratio trans it would be much more managble. That much low gear in a light car will keep you busy adjusting it. Mine was like a tractor. Spinning the tires or standing straight up. :-) The big RPM drops at shifts don't help anything.
Think tech would notice a metric 200? LOL

YUP.. had that problem when I went to a 3200 Stall Edge Converter.
Bryan Herter send me a 1-2 Shift Bin file to fix that problem.

Based on my Cam and Engine and Dyno Sheet.
The Stall limit for my car is 4200rpm.
