Need guess's
 

so basically my new setup is,
texas speed headers with y pipe
qtp cutout
custom comp cam 230 230 112+2
243 ported heads
3.73 ratio

what would be the whp ? and aprox what would be my drag timing

my previous setup,
gt11 cam
same bolt ons

378whp 362

384/368

im thinking 400rwhp :hail:

Mid 390s

How did u like the gt11?

it was a very powerful cam for zero race's only needed a good tire for grip, power range is from 1600ish rpm changed to a bigger cam... il update this when i dyno my car soon enough

What are zero races? From a dig Im guessing?

390/369

Were your previous #'s made with the ported 243 heads?

auto or m6 ?

should clear 400 rw fairly easy if the heads flow decent.with a ls6 intake i'm assuming and m6 i'd say 410-420 rw and 385-390 rwtq. just a blind guess but fwiw i made 436 rw with a 228 cam with ported 5.3s and a fast 90.

without knowing anything about the port work on the heads, no way to know...could be worse than before if whoever did it hogged them out

if they are decent, around 400rwhp

if they are professional, closer to 425+ rwhp

I solute you and your 1st grade reading and comprehension level. ;)
