    Schumacher bolt through 727 rear transmission mount, anyone using?

    I was just looking at the Schumacher bolt through rear transmission mount for my 727, the factory one is already shot in only a few thousand miles. This one looks pretty solid, a bit expensive, but worth it if it doesnt fall apart like the factory style one. Anyone using one of these?

    Vibration damper bolt torque spec, 100 or 135 foot pounds

    Interesting dilemma for the torque specification for my vibration damper bolt! My 73 service manual states 135 foot pounds in the install instructions but the specification sheet in the manual for the 340 states 100 foot pounds. I also looked in my old Chilton's, and it says 135 except for 71...

    Anyone change small block timing chain cover gasket with out dropping oil pan?

    I am curious, I have read a couple of threads, but it was clear if anyone has changed a small block timing chain cover gasket without removing the oil pan. I really don't want to go through the process of pulling the motor to change the oil pan gasket while I am doing the timing cover gasket...

    727 Shifting from 2nd to 3rd is sloppy, what could it be?

    So, the more I drive my car since its been restored, only 600 miles on rebuilt trans, but I have noticed the shift between 2nd and 3rd is hesitant, almost feels like its trying to go into 3rd before 2nd is disengaged or maybe even getting a bit neutral before the shift to 3rd. This happens when...

    Timing chain cover gasket leaks coolant when water pump bolts removed? What to do?

    So, I removed my water pump, was going to replace the gasket and use some thread sealant on the bolts, and was blowing air into the bolt holes that go through the timing chain cover, and noticed there was air coming out around the timing chain cover where the gasket goes. So, should I change...

    Reverse Ligts only work with Neutral saftey switch is out of the tranny

    A bit puzzled as my reverse lights only work when I remove the neutral safety switch from my 727 transmission. I tested with two new switches and same result. When its installed in the car and hooked up, the neutral safety part works, but no reverse lights. I'm beginning to wonder if the...

    Single snorkel air cleaner. Does it really allow enough air flow????

    I was just thinking the other day while working on my thermoquad and how much it really growls when opened up and now that I am running higher compression and bigger cam, will the stock single snorkel air cleaner allow enough air flow for the motor or would it be better to open up the flow. I...

    A bit puzzled with my timing, mechanical only on my 340, who can help me?

    So, long story short, my builder stated I should set my timing at 17 degrees BTDC, and the distributor is only using the mechanical advance with the 272 cam installed on my 340. So I have been running like that for a while, and it runs good, but since I started tuning the carb, I noticed when...

    Thin blue smoke on fresh rebuild, normal or not normal, that is the question?

    So, I fired up my 340, just rebuilt, most likely only a couple of hours on her, the builder did the cam break in, told me to change out the break in oil when I get her running, and I did that, refilled with Brad Penn 10w 40, oil pressure looks good, middle of the dash gage, but there is a bit of...

    Spark plug cross reference Autolite to Champion?

    Anyone know where I can find a cross reference for Autolite to Champion spark plugs? Just curious, as my motor used to run Champion rn12yc's back in the day, but the builder put in Autolite 66 plugs, guessing these are a bit hotter, because of higher compression and bigger cam. Just want...

    727 cooler lines running with, you guessed it, TTI headers?

    So, anyone with small block able to run the stock 727 trans cooler lines? Or did you have to do something custom? I didn't see any application notes for this issue from TTI. Guess I will call them again, but if you have run lines, let me know how you did it!!!!

    Zinc Oil and Zinc Oil Additives, for flat tappet setups, recommendations?

    Just wondering what everyone is doing for either zinc oil or zinc oil additives, as my 340 will require the use of zinc oil. My builder mentioned some brand name they user, forgot it at the moment, but would like to know what everyone else is using whether its zinc oil or regular oil with zinc...

    Drive shaft orientation?

    I sent out my drive shaft to get checked for balance and true, and they called me today saying that the yoke on one end needed replaced because the u-joints don't seat properly. anyway the end he mentioned was the wide end of the drive shaft and he stated that is the end that goes to the...

    Where to get 727 tranny tail shaft mount insert?

    Does anyone just make just the insert for the 727 tail shaft mount? I have seen plenty of complete mounts, but mine is good and just needs a new insert, similar to what was done with the engine mounts? If you know where to get let me know, cant seem to find, maybe i am not searching correctly.

    Pinion flange seal, anything special about replacing it?

    So my newly rebuilt carrier has a leak, and hasn't been driven yet. The seal on the front of the carrier where the pinion flange goes in has a slow drip. A mechanic buddy of mine indicated that special tools are required to change this seal, and I should just pull the carrier and take it back...

    Anyone know the CFM of thermoquads?

    I looked at the Thermoquad Guide sticky, but did not see any CFM information. My question, would a TQ-6322 be over kill for my 340 with just a slight bump in compression and a taller cam? Originally the car had a 6319, which i believe is 561CFM? Looking for something in the 700cfm range.
