Funny this came up today. i just switched my Duster over to an 850 alcohol carb and was going to go to our local tracks test n tune but I never finished it up till 2pm so if the rain holds off I may hit tomorrows race at PRP to see what she does.

Edelbrock headed 408
5.984@112.52
422 Indy headed small block
5.982@112.56 mph
