funny seeing you here. galant replacement?

I would have to see the flywheel because I have no place for a working pilot bearing, if the flywheel has a center that can hold a pilot bearing it could be done , but it may be over load the coupler with the stress inputs brought in from the rear wheels back through the driveline that I didnt have to deal with in an auto trans set up

same user name from nyccdsm and gvr4.or. you might be able to use this flywheel with the adapter plate. the starion and dsm share the same bolt pattern for the flywheel. http://www.starquestclub.com/forum/inde ... opic=74767

just a thought.

Bill, according to Neal racing trans, the converter is supoosed to have .120" to .100" of play, so if you have this set at .125", we should be good as it can be shimmed slightly to take up the slack if need be. The extra .005" probably isn't a big deal for 95% of guys anyway.

this system will work with a 4g63 or is it 4g64 only??

would love to put it in '92 gsx...

I believe Bill will have both wide and narrow block versions available.

Bill Hincher · Post by **Bill Hincher** » Mon Nov 03, 2008 2:30 pm

yeah, that adaptor is built both ways, narrow and wide block, I just drill out the proper bolt pattern for what the owner wants

Bill, have you had any time to work on the adapter revisions?

77amc · Post by **77amc** » Sat Nov 15, 2008 1:09 pm

Bill, is it any more expensive to have both patterns drilled?
Or would that give any integrity issues? (not you, the plate)

Bill Hincher · Post by **Bill Hincher** » Sun Nov 16, 2008 8:50 pm

hello, I took a short break to get my outdoor work done before the winter storms come in, but, the adaptor plate will not accept both patterns drilled into it because the lower bolt holes are spaced too close to each other, it would have an oblong hole.
And yes I have started to remake the adpator plate , I used the time I have been away to aquire some new tooling to help me do a better job on the coupler......sooooooooooooo I am back on the GM adaptor, I will be posting pic's

89coltgt · Post by **89coltgt** » Sun Nov 30, 2008 10:30 am

Bill, are you making two seperate plates for the wide and narrow block now or just going with the narrow blocks?

Btw, anyone know what the difference is between the two piece and one piece rear main seal flexplates? I see some places sell just a 153 tooth flexplate and other have them seperated by the type of rear main seal.

Bill Hincher · Post by **Bill Hincher** » Tue Dec 02, 2008 10:15 am

the plate will share one design, the difference will be in how its drilled, I been bouncing around about the thickness, also i tried some new ideas on the starter location.
I finally settled on the starter location and thickness is still up to the coupler I want to use, the problem I am wrestling with is the crankshaft bolts.
the original M/T crankshaft bolts have a bigger head for more clamping force but they are designed to work with a flywheel 10mm thick, the auto trans bolts are designed to work with a flywheel 3mm thick, If I swap the auto trans bolts for the M/T bolts I will gain in strength but the fingers i used to locate the center of the torque converter will be much thinner, however the thicker coupler will force the trans to be mounted an extra 1/4 back with the adaptor plate
so i been bouncing back and forth

jeffball610 · Post by **jeffball610** » Tue Dec 02, 2008 5:25 pm

So by using the M/T flywheel bolts you gain both strength and will not need the extra 1/4" set back? Sounds like a win win to me. I see the need to have a thick mount for the torque converter, but where is the benefit in that? Will it be that much stronger? What has Buschur done with his mounting?

I think you're definitely on the right track. The only advice I have is to keep in mind that the people using this option will likely be running really high HP engines. So the parts should be able to handle that power. I know you've considered this, but I don't want you to forget. Sometimes I get close minded when working on projects and forget simple things like this.

Bill Hincher · Post by **Bill Hincher** » Tue Dec 02, 2008 5:48 pm

the gain in the M/T crank bolt is in the size of the head, it has a broader shouder and picks up more material to clamp against the flywheel, but using them will space the bellhousing back the extra 1/4

89coltgt · Post by **89coltgt** » Wed Dec 03, 2008 2:35 am

Will there be an issue ith the coupler being another 1/4" thicker Bill? I think the 3/4" adapter plate will be fine as long as everything is lined up and centered, plus the inside of the plate can be lightened up by milling out some of the extra material that is not necessary for strength. Also, with this thicker plate, you would have more thread depth to work with if you wanted to add some lower braces like the bellhousings have.

I am one of those guys that jeffball speaks of, or at least I am planning to make a good amount of power with a moderate stall/transbrake.

I guess my question would be, if you go with the 3/4" plate, will that allow you to use the manual bolts and give you a nice thickness for the converter "fingers"?

Bill Hincher · Post by **Bill Hincher** » Wed Dec 03, 2008 12:24 pm

I am just playing with ideas for the final pattern

this is all cut to 2% oversize for the shrink that will take place during casting

89coltgt · Post by **89coltgt** » Wed Dec 03, 2008 12:38 pm

Bill, are you going to integrate the extra mounting points into the adapter plate?

Bill Hincher · Post by **Bill Hincher** » Wed Dec 03, 2008 1:19 pm

one step at a time, they are there to be used

Post by **DJpowerHaus** » Wed Dec 03, 2008 1:30 pm

how hard would it be to make a wide and narrow plate if you just clocked the bolt pattern rather than just overlaying them?

DJpowerHaus wrote:how hard would it be to make a wide and narrow plate if you just clocked the bolt pattern rather than just overlaying them?

I dont understand?

this is a pattern being built to be one piece, it will be about 1 1/8 inch total width, the original plates I built were 3/4 wide. I am extending the block mating surface so they can be cut either 1 inch or 3/4 but the plate will have to be drilled upon request to wide block or narrow block. the adavntage being , that I can get a very square , flat surface for engine to trans surface, as opposed to two plates back to back, that can be hard to get square
when I think of clocking the bolt pattern, I think of the angle position of the engine, as in rotating the engine one way or another

Post by **DJpowerHaus** » Thu Dec 04, 2008 10:29 pm

I'd see it as clocking the transmission rather than the engine since the transmission crossmember will need to be fabricated anyways.

89coltgt · Post by **89coltgt** » Fri Dec 05, 2008 2:21 am

On an automatic trans, the trans should be level, not tilted to one side.

Bill Hincher · Post by **Bill Hincher** » Fri Dec 05, 2008 2:21 pm

I can understand the need clock the right, to the original position, it would lower the under hood hiegth and move the engine away from the master cylinder
I have asked about it before but nobody seemed to want it

89coltgt · Post by **89coltgt** » Sat Dec 06, 2008 2:21 am

I myself, as well as many others would prefer a narrow block version that will position the engine/trans stright up and down. Bill, you will find that most of the guys looking to build a project using this adapter will be using the narrow block 4g63/4g64.

Bill Hincher · Post by **Bill Hincher** » Sun Dec 07, 2008 7:21 pm

it seems like most guys want it for rail jobs and drag cars, hood clearence doesnt seem to be a problem

77amc · Post by **77amc** » Thu Dec 18, 2008 5:10 pm

John, SO, how much does the engine stick up and why would it be at any angle?

I really liked the flipped exhaust mani but know that it would raise the turbo and if this raises even more, then I may have to stay with a stock turbo housing.

I think that more peeps would like the narrow version just because there are tons more fwd 4g's out there..

Hello. New to the forum. Glad to see I'm not the only one looking to put a chevy trans behind a mitsubishi. Your adapter looks great nice work. Was wondering what you currently charge for these? I'm lookin to put together a 300 or so hp 4G63 narrow block with a turbo350 behind it. Looking to buy an adapter setup round the middle of January. Thanks!

Bill Hincher · Post by **Bill Hincher** » Mon Dec 22, 2008 9:20 am

i been charging $275.00, I am kinda worried about the casting shop
The guy I work with does proto type work for GM and Ford, I am worried that he might have to raise his price because of the bailout problems with the big 3

Bill Hincher · Post by **Bill Hincher** » Tue Dec 23, 2008 5:29 pm

this is the problem I have been working on for the GM adaptors, the flywheel bolt on the right is an Auto trans flywheel bolt, its storter than the manual trans flywheel bolt and has a smaller shoulder surface under the bolt head

the original auto trans flex plate was 3 mm thick, my first couplers were 7 mm thick under the bolt head

I keep working out details in the new plate, I want it strong but light

This is my new coupler , it has 10 mm thick flywheel bolt landings and uses the Manual trans bolts

The flywheel fits okay but the starter depth will need adjustment

My first plate were 3/4 inch thick, the new plate will be closer to 1 inch

I will have the new adaptors in the casting shop this weekend ( just after Christmas ) then I gotta finish the t 56

Bill, did you get to snap some pics of the finished adapters?

noooooooo I didn't >;O) it went straight to casting i worked and worked and worked on it and finally took it down to casting , I just got tired of it ! >;o)

the casting shop went from 14 guys to 3 guys in two months! because of the GM, Chrysler bail out problems, I hope he stays in business

I went to the steel treatment plant today ( they do all of Hydromatic's stuff here) and got a cost on the harding proscess he figures about $20.00 per copy
they said I could have this material ( 4140) hardened to any 'brill' number required

I have to rethink the coupler to allow for .003 thousands shrinkage, so all the spec's have to be changed

they thought about ' 50 brill'

it would have been a 'horrible' thing if we lost Herbie

the company cammander said it would be an ' horrible thing' to loose herbie

true story

Hey that's my name. Use to go by Herbie when I was younger. No relation to the story though.

Bill, are these adapters for sale or are they still under production. I haven't picked up a powerglide yet but I plan on using one of these when I get to that point. Nice work by the way.

yeah, they are done, pm me when your ready let me know , wide block or narrow and give me a couple days to cut it and box it up

I should do a couple now but I want to close the deal on this T 56
