10s for 10k can i do it?

When I finished my duster it went 11.50's at 120mph. It 60ft'd bad...street converter, street suspension, etc....
Changed all that and it started going 11.00's. Kept plugging away at it (I only race a few times a year it seems) and now it runs 10.50's with 560HP W2 360.
Total cost from everything including price of car, paint, dana 60, trans, interior (all redone) and all safety equip., and me doing the engine I'd say roughly 25K!
But I didn't need alot of the expensive stuff I have...I did it so that I could race anytime I wanted, not have to work on the car much (almost never touch it aside from washing it) and peace of mind that I overbuilt area's that take abuse.
