Think i might be able to squeeze out 450-500rwhp?

 

On the juice I think you'd meet within your target goal.

Looks similar to what Siver-mod-o is planning on building.

 

you could go with a 6.0 and probably save a little $ from the machine work you will have to do on a 5.3

 

but that would require me to buy a 6.0L long block just to start off with not knowing whats actually wrong with it until i tear it apart....

with the 5.3L short block i have already in my storage facility including the 243 heads i recently attained i could pretty much build a mildly modified Ls6 motor with ease of mind

If i'm not mistaken the Lq9 has 345hp/380trq stock

the ls6 motor which is almost the same as the ls1 besides ls6 intake manifold, ls6 cam, and heads produced 405hp/400trq

So that leads me thinking that if i go with a better cam, p&p ls6 heads, 75-200 shot of nitrous, tune and all the other mods i have that will interchange over

I'll have close to 500rwhp spraying 150 shot... From what i've been reading the stock crank will handle a 200 shot fine with proper tuning and adjustments with the forged pistons and rods i could be seeing 550+

I got to say........5.7L FTMFW!!!

 

Check with turbogibbs i think he still has some forged stuff for a 5.3 for sale.

 

LMAO! Git some, brother, GIT SOME!!!
