Assuming a race weight of 3850, 10.50 ETs need 657 hp. Lets say you settle on a figure of 680 hp as what you want so you have a little margin. You can do that with a stroked big block with a set of ported SR heads. Check out the dyno report on a 512 built by Maximuswedges. Very street friendly combo, not hard to build or maintain. To overcome the difference in compression for street, a bigger cam or street roller cam may be needed, but you will be there with a motor that is not high strung.
