WANTED 727 flexplate bolt

[Maindrian Pace]

In preparing to bolt the 727 to the 440, I found that I'm missing one of the six bolts that hold the flexplate to the crank. Looked everywhere, pretty specific bolt and I'm stuck until I find one. Anyone have one in the Phoenix AZ/east valley area?

I probably have one in one of my buckets of misc bolts...I tend to keep every nut, bolt, clip, washer when I part out a car, motor etc, but I'm up in Northern Canada. I'll take a look an see if I can find one, if you need it you pay for the ride and Ill send it your way.

I have one or two....

Thanks for the replies fellas, I found one from a local Mopar guy, but now I have bigger problems. I just right now got done mating the trans to the engine, admired the assembly, and the fourth small flexplate bolt, plate to torque converter - stripped. Not the bolt, the pad. New TC supplied by the trans builder - 6 years ago. Not sure what to do now.

Heli-coil it.

Seriously, that is a good repair that done correctly, will be stronger than the original thread.

I did all my road wheel center mounting holes after stripping a couple out. This will give you an idea of the process. Road Wheel Thread Repair with Heli-Coils

Yup - I got some too! This is just some of mine. I just don't like to reuse the old ones especiallty when you can buy new fairly cheap.

As far as stripped threads in converter, I just helicoiled one in my race car. I have no concerns and it is 3500 lbs and makes 1060 hp. You will be fine too! LOL!

I do however use ARP 200-2902 bolts that are longer than stock (0.680"), use red loctite and torque to 50 lb-ft.

Thanks guys, I just got the heli coil kit and the 21/64" drill bit, we'll see how it all works out tomorrow.

Helicoil kit worked very nicely, all back together now and ready to drop into the Monaco.

Good job!

Do I see a washer under the bolt head? Do not use a washer anywhere on the flexplate hardware!!!!!

 

[Maindrian Pace]

That washer was there only to test torque the bolt in the pad, it simulated the flexplate. All bolts were installed with blue Locktite, no washers.
