Installation of the transgo tf-2 kit was pretty straight forward. Since I have a later model 727 it seems that I had less drilling to do then if I had an older model.

Here's the valve body pre-transgo

Couple mods that need to be done in the kit.

Drilled out separator plate holes. No you can't tell from this pic but here it is anyway.

Last post for the night here.

Here's a couple pics of the smaller shift shaft seal that is on the actual arm itself. The other seal is seated into the 727 casing.

The po had put this particular seal (small shift shaft seal) in upside down when it was redone at some point. Maybe why it was leaking so badly. I could see this seal being very easy to replace once the kickdown linkage is removed. Most likely both seals would be leaking though.

Here it is no seal.

Here's a couple pics of the pan with the new fangled mopar gasket installed. Love the fact this pan has a drain plug. Why anyone would ever make anything full of fluid without a drain plug is beyond me.

Still have one more fitting to replace on the radiator/trans cooler line. It leaked a little when the trans had some fluid so I'm erring on the side of caution and solving the issue before I fill the trans again. Fingers crossed everything was done right. Would love to drive her for a mile or so tomorrow.

Oh yeah almost forgot that I picked up a nice little piece from IH Parts America. Love this new air cleaner nut. Thing looks awesome.

Good work. This might be a little late in the process, but I'm noticing the grooves worn into your shift shaft which is typical of a high miles unit. Those grooves can present sealing issues even with a new seal in place. Sop is to sand the shaft down with some emory cloth until your fingernail doesn't catch on any ridges. Hopefully yours won't leak from the seal any time soon, but if it does, you'll know why.

I should have done that. I was afraid it would take off too much material though. It was all smooth except for those grooves which I suspect will be the cause of an early leak. I've run it the last couple days and shifted through the gears and no leakage yet. We'll see when the linkage is properly adjusted and I can drive it again. Fingers crossed.

Got the linkage all set on the transmission. Took quite a bit of time but now r is reverse and d is drive and so on.

Holley 20457s brand new carb with spacer.

Idle is at 1100 in park and drops to 6-700 in gear then tails off. No binding in linkage. Idle set screw a all the way out. Truck is dying after about 5-10 seconds of being in gear with the brakes applied. It reacts fine when I initially put it in gear then stumbles. Reacted the same when mixture screws were 1 1/2 turns out also. Seems like too much fuel to me. I have set timing to 8deg. Mixture screws are 2 turns out. Pretty much everything in the system, ignition and engine, is new.

Tomorrow I plan on:

hooking up vac gauge to get 20+ vac reading
checking for vacuum leaks
adjusting mixture screws

anything else I'm missing?

After truck dies in gear it is difficult to start. Starts great when sitting overnight.

Cool deal hope to see it rolling around town soon. 1100 rpm in park seems a little steep though.

Got the truck idling solid at 900 and 600 in gear at 18hg vacuum and 10* advance. Doesn't die in gear.

Had some cooling issues that I started a thread on the bp to help find the issues.

black sludge in radiator - binder planet forums

Seems like I've been able to clean out all the rust and crud from the cooling system. It's only had water to this date and there was probably a bit of rust that needed to be cleaned out. I borrowed a combustion gas tester just in case and I will be running the test tomorrow.

I ran the truck tonight and it sounded great.

Fingers crossed.

I can't keep the truck cool with the engine mounted fan without a shroud. What a surprise. So instead of buying an aftermarket/used fan shroud and trimming it to work with my body lift I decided to go with an electric fan. I started with getting a taurus fan but the depth of the overall fan turned out to be too much. I just couldn't make it fit without major modification which I decided wasn't worth it. So I then switched gears to dual fans. I went this direction because I wanted a high and low fan setting and they were just as good as a larger, dual speed fan. Picked up two flex a lite curved blade fans that I installed on an aluminum shroud that I cut to make them fit. Love that the fans say "made in the usa" right on them. They claim about 900cfm apiece and I feel that will be plenty to cool the truck.

Here's a couple pics of the fans mounted to the shroud. I will be using a jegs dual fan controller to run the fans.

They're not the best cut circles but who cares when they're covered with fans.

Fans are all dialed in and working great. Truck stayed right at 185 while running at 3k rpm for 20 min. Excited to be able to start tuning and working out the kinks since I can run the engine longer then 15 min. Pics of fan install coming soon. Lighting was no good tonight.

Garage is just to dark to get a decent fan pic for the time being.

I have been able to spend the last two days tuning the engine since I can run it as long as I want finally. I think I've got it dialed in but would love some advice/feedback on the numbers. Yes I know it May change under load/drive.

"crate" long block 345 engine, balanced, comp rv cam, new pertronix in a prestolite, mallory hyfire, matching coil, new plugs, wires, cap, new Holley 4160, dual to single to dual exhaust, smog pump attached and hooked up, all vacuum plugged, aluminum radiator, dual electric fans(stays at 180), and maybe something else I forgot.

Numbers:
17 hg vacuum at 700-800 idle in park
10 btdc
idle mix screws right about 2.5 turns out.
No stumbles off idle or anywhere up to 4k with no load
brakes applied and put in gear idle drops to 500ish. Seems like it's hurting but never loses its gusto or dies.

It really seems like after all the reading and studying I May have tuned it pretty well. The exhaust smell alone is much less pungent.

I will get it under load at some point this weekend to really get a feel but have a couple questions.

Should I increase idle for better vacuum? Say 900. At 900 I'm at about 19.
Does my rv cam mean I should expect less than 20hg vacuum?
Do you see anything I might be overlooking?

Thx

That is right about what I'm seeing with a comp 252 and 390cfm 4160. Same hunting issues too.

Thx chappie. I'm running a 260 comp with a 600cfm Holley 4bbl. I raised the park idle to just under 1000 and it now idles in gear really well at about 550-600.

I can't get quite Rich enough which is the reason for the slight surge. Manual trans here 550-600 idle rpm.
