You guys running 383's, what sort of head/cam combo's are you running? Specs? I would like to make safely over 450RWHP on my A4 and I dont think it will be too diff with the right setup. If anyone wants to chime in on what all is done to the motor it would be greatly appreciated! ...as far as crank, rods, pistons, what heads, what cam, springs (single or dual), all the way down to what head gaskets you are running. Just want to see what people are using a learn from it so I can make the right choices while selecting which parts to put in the motor..

I am going forged bc I will be spraying probably 200 shot max. F2 kit maybe?
Eagle or Lunati?

Thanks

Cannot beat Eagle for the money, and they are very durable to boot.

do a search a you can find out everything else including dyno graph.
Im sure 11:1 with LS6 heads would have put me way over 500rwhp...but it was not in the budget.
