Seriously!!!

If they bought you a 318 balancer for a 360, they don't know what they are doing.

Unless you told them to get it, no engine I've ever built did I buy a flexplate for unless it was agreed upon before hand.

They likely aren't shelling out $80 because they need to get it balanced. I wouldn't!

Don't weld weights to the converter... Keep it neutral balance and use the correct flexplate.

I believe I have a 10236 plate for a 360/727 around here. If you want to buy it let me know. That's the easy way to fix this.Be
