So I recently have started my build with a 6.0 thats stroked to a 408. But my issue now is the stupid 8mm Allen bolts that are on the 4l60e. I have the ls1 out and the trans is still attached but the problem ia the dozen or so 8mm Allen I used none of then fit there too big so I tried a 7 and 6mm ans they were to small. I also tried standard Allen as well thinking they may have not been metric and non of them work. I am really at a loss what can I do to remove them non of the Allen's work. As anyone else had this issue?

 

Post a picture

 

I'm home now the car is at the garage but I can get one tomorrow afternoon.

 

You talking the bolts

 

the 3 bolts that hold the flywheel to the converter.

 

You need to heat them first then hit with an impact. They are standard allen head, nothing special.

 

that's the thing no matter what allen I put in none of them fit either to big or small no in between so Idk if some one did it before and screwed them up idk

 

I think he meant try SAE allen sockets. Sounds like you need 5/16 or 1/4. It’s been a long time since I have done it

 

I tried those as well and nope nothing

 

just did a converter swap this past weekend it's an 8mm

 

hope this works haven't post any pic's the photebucket bust

 

and then I replace those crappy 8mm bolts with ARPs....best 13 $ you will ever spend
