It the time, I’m not sure if they made one for a BOP so I made my own at work out of 1/8” steel.

3/16 is the way to go. All the thin ones end up bent

Use chrome-moly plate.
Stronger plus lighter. (when using the thinner 1/8")

You can Use a Chevy plate, just make it fit installed backwards for starter. If using factory block, just weld a couple of tabs up top where trans bolts to block.

My converter was not made with a mid plate in mind so I can only put it mack so far. If its made out of high grade steel that would be great. I use Alston stuff. High quality. |

Called Alston and they do make a 10 gauge mid plate more designed for stock frames. A little wider side to side. But its like 180$ vs the 60 bucks for the .100 thick plate.

Called Frank, guy is great. What I have to do is put the converter up to the crank with flex plate on and set it back the 3/16 with washers. And make sure it is centered exactly. Some converters are different/tapered. Its all about being centered , not the tangs for the pump.
Also he makes a front plate for my frame too that has nothing to do with timing cover so its pretty easy. Even if I have to go with a .100 in the back this front plate is the way to go. Off with the elephant ears. They turned out really nice but put pressure on the head. One thing with iron heads but going to aluminum. |

How long does it take you ? I thought about it but if I can buy one for 60$ or 90$ that's more than worth the time and hassle.

The plate will need fitted around your headers and frame width more than likely. I have a few patterns I can use after I put the engine where it belongs and cut one out in a few hours. You have to make sure your snout on the converter is in the crank to. I run ati converters and can change the pilot out for a longer one. They sell correct shins for the ears to
