Things seem to be dead around here so here is something to throw in. What do you guys think? I have my own ideas but currious what the people think.
The L92 heads will be unported for the most part. They flow 328/214 cfm @.600" lift out of the box. For comparison Patriot stg3's and AFR's flow in the 320's/240's range but the L92's mid lift #'s are fairly strong. Here is the set-up:

-370 ci, .030" over 6.0L
-L92 heads unported 2.16/1.60 valves
-GM L92 carb intake with 90mm TB and LPE 100mm Mass air sensor
-60lb injectors (too big but I already have them)
-226/230 .585/.592 116 lsa comp XER lobe
-11.8:1 compression
-Pacesetter coated long tubes with ORY
-6 speed T56
-4.30 rear
-275/55-20's

 

420'ish.../450'ish...

 

knowing how things work with those heads and etc..depending on how they act to the cam i say around 470rwhp - 510rwhp

 

I'd like more but i'd be happy with 450rwhp. The cam will definately be the hold back. But i'm ok with that. I'm looking for a fun DD not something i'm willing to sacrifice drivabilty for power.

 

Hey turbo where will you be getting the 4.30 gears from? I've been searching for a set everywhere and havent been able to find them ANYWHERE.

 

where's the "not enough" option?

 

Summit

 

Hey, if I can get close to or exceede the 445rwhp my 4.8 put down with 13psi, radix, cam, headers, meth, upgraded heat exchanger, 31* timing etc. I'll be happy and won't be running around on the ragged edge. I know it won't put down the 489rwtq that the 4.8 did but it will still be fun and weigh ~100lbs less without the heavy *** charger on it.

 

430-450rwh

 

That's a good bit of compression for pump gas isn't it? Not saying you can't run it, but I'd imagine you're gonna have to give up some timing to avoid detonation. Are you talking Dynojet or Mustang Dyno? I'd be surprised if it made 425 on a Mustang Dyno. You might want to try to sell those injectors and get something in the 44lb. range
