454 ideas?

[70nova]

I have a recently rebuilt 454 making 400hp/500tq
It came out of a truck i dont know the year exactly. Im on a pretty tight budget and was looking for opinions on what i could do to increase the power.

The heads are heavily reworked ported polished etc. stock heads
Edelbrock Air Gap manifold
Hooker ceramic headers
Hyd. cam
cam lift .296 .311
valve lift .503 .529
duration 292 Int. 302 Exh.

Holley Double Pumper - i dont know what size

Any suggestions on heads or cam or combinations of the two.



like i said i just had the engine rebuilt, and installed inthe car last year so would really like to do this with out pulling the engine again.

any suggestions would be really appreciated
