Default 153 tooth 80e Flexplate

I have a LT1 mated to an 80e with an FTI converter in between.

From FTI it has a 6 bolt hookup with a 11.5 and 10.75 diameter patterns. I would really like to use all six bolts but can't seem to find a flexplate that covers both.

Needs to be SFI cert and externally balanced.

3 bolts holds a ton of power, way more than an LT1 is gonna make

I am not sure if the bigger 11.5" bolt circle will fit on the smaller 153 tooth flexplate. I think it will hit the ring gear. You might need to convert to a bigger flexplate and you can find those in a dual bolt pattern. But like Forcd mentioned, 3 bolts holds a lot of power.

Def. I mean, LT1s can't make any power right?

Ouch... I bet that hurt. We have our 3 bolt setup in 1000+ HP setups, maybe just some weak bolts. Do you know what grade the bolts were? And upgrading to 6 would definitely help, just not sure you will get there on a 153 Tooth flexplate.

They were the supplied bolts with the torque converter, ordered ARP stuff for the new flexplate.
