How much power can these alum 5.3 blocks handle on the nnbs?

[George C]

the number 7 shit is bullshit. a motor fails cause it was mistreated or improperly handled. a 5.3 should easily make 800 rwhp without a hiccup if in the right hands and given proper support. Like cool IATs, cool ECT, good tune, smart driver, good tune.

also to get 500 hp i wouldnt consider 2 power adders for such a low hp level goal. 500 is roughly 9-11 psi. two power adders is just an excuse for the lack of another. Plus its more complications especially for such a goal as of 500.

i think ducky has been unhurt for several years at 500ish with his 5.3, trevor1 has well over 600 on a 5.3 for many years now, im sure theres others but those are just to name a few

was waiting for you to chime in....how's the camaro doing?

[TvsQuez]

I just don't feel I need to do a swap when I feel my motor is a perfectly good motor still. That's all i'm putting to it is 9-11psi, and i'm good. I just wanted to add on meth, new heads, and maybe a shot. I keep being told to just do a 6.0 swap, and i'm just not buying it for some reason. I keep hearing the 5.3 is a strong motor, and to stick with it too because there's more potential in it. Thanks for the help everyone. Are there any suggestions at all? like bottom end?

i know quik did arp rod bolts...think lambo did the same. Probably a good place to start

[TvsQuez]

I was thinking of doing that. Been looking online for something.

I have an brand new forged lq9 with 317's machined blue printed waiting for me if I want it. Originally what I was going to do was put that in. I just don't know if using the money for that motor, and using it to install all of this would be the right choice. If i did the motor swap, i'd come outta pocket. If I didn't, i'd get all the upgrades i'm talking about. meth, nos, heads...opinions on this? thanks guys.

I guess we don't know how to handle the power...is that what you're saying? Seems like an awful lot of people have had the same problem...must be a f**kin conspiracy.......

[rutroe]

Nevermind...I don't have the patience for whatever answer you have...disregard....

[sprayedenali]

youre gona swap heads, add a meth kit and nitrous kit but you dont wana put on a different pulley cause you have to re-key it or whatever? ok...

[TvsQuez]

I have the roush kit. Nothing is for sure with this kit. Even if I try re-keying it, it's not definite. Only one person so far has done it, and there's really no feed back on that. That's why re-keying it is kinda up in the air. I never said I wouldn't, i'm asking for opinions from everyone on the board. I'm just throwing my thoughts out there, and want to hear what you guys have to say.

[sprayedenali]

ahh, ok. makes more sense now. one way or another i bet more boost would be your best bet, and easiest way to get some more powerssssssssss
