Roadkill Garage gets the Crop Duster in the 10's!

I must have missed some episodes somewhere. What is the current engine and build configuration? I thought they had a 440, then swapped it for a 383; but no ideas what they did build wise, to the engine. I saw the episode where it looked like they finished it, then did burnouts all the way down the road. Does anyone know the current engine details?

It's the 383 block that was in DF's Superbee when he first got it. He said he has owned that block for 30 years or something. Stroked to 440 with the same same Edelbrock heads and cam that were on the original motor when they first BB'ed it.
