Hi Jay
It's a 427 Smeding Cobra dart block Dynod at ~585hp at the crank. I don't think there is anything broken in the side pipe but if there was say a broken weld in there, would removing the side pipe and shaking it reveal anything?
Thx
PS
Sorry for the multiple IDs, I couldn't log on with this ID for some reason so I had to create a new one. Now it seems to be working again
