Harmonic balancer

I kind of thought that’s why it’s different. But will the flexplate from a cobra jet C6 tranny work on my FMX? I hope so because I already ordered one. And what’s the weight size? 28 ounce?

If this is a 351C, yes.

Call NPD and ask?

Yeah I’ll call them and let you guys know what they said

Gave them a call and it turn out I purchased the correct flex plat and he said it would fit on a FMX transmission
