72 duster 360 NA to 390 Turbo

I’d love to hear how your combo does with an s480.

As for that Wh1c, it would be a good turbo for a 4 cylinder. Don’t buy it.

It's overpriced anyways at $300 cdn.

But I am pretty curious how to go about a turbo big block set up. Nothing crazy , say no more than 8 lb boost. 500 hp on the motor
