I ran a similar combo, but 460 inches, and big shot plat. went 8.78 so your goal is very achievable.

im kinda curious how the dove heads will react with the nitrous hope its not a wall and im limited ...prob will be .....

i was tossing the idea of i should of just bought p51 and did it n/a

doves work well with nos,and if their ported good all the better

If your trying to go mid 9s you will be more than fine.

any idea what kind of power this thing should make and .....what does this combo prob run on all motor before spray ? i have no idea i just wanna run in our 9.50 index class ..........my kit goes from 150-400 nitrous shots

I know of a stock suspension 508 D0VE headed deal that runs mid-high 9s NA and runs in the 8s on spray so you 521 SHOULD have no issues running similar.
