How much power do i have here?

[DarKnight]

hi guys

just wanted to get an idea about how much power i have on my cuurent motor.

stock L48 350 4-barrel, Q-jet, performer intake, mallory HEI with race module, K&N air filter, hedman headers elite, flowmaster 2.5" with h-pipe and delta 40's.

this is a 72 monte carlo from California, but i stripped the smog pump and a/c.
it runs with a performance build 700r4 to the stock 12-bolt 2.73 dead-leg.

if anyone has any ideas, let me know please.
