Where did you get the info or how did you come up with 550 rwhp safe? Shouldn't it be based on motor hp vs. rwhp because a manual setup is going to put down more than an automatic setup. The best way to determine this would be by checking duty cycle, but how is this done?

 

I think I got it by removing the "rw" from "rwhp"

I tried to draw attention to that fact by using bold for the "rw" in the "rwhp" that follows.

Here's an HPTuners screenshot (pulled from their site). Duty cycle is just a line on the graph.

 

This is a big concern of mine. If the injectors end up not being enough, then I already have a back up plan as to how I'm going to make a set of SVO 42s work. I wanted to know an esitmate on how much the LS7 injectors would support. In my opinion it should be based on motor hp rather than rwhp, because an automatic will show less hp on the dyno than a manual, especially how radical an automatic is setup. So to me, the best way to know whether or not they're "good" enough would be to verify duty cycle. My car is tuned with LS1Edit, so I don't know if duty cycle will be displayed or something that will have to be calculated based on other numbers. I just wanted to get a estimate as to much they'll support to have a good idea if they're going to be enough or not.

 

I feel like I'm answering the same question over and over and over again.

 

I know nothing about tuning. You posted a pic of HP Tuners showing duty cycle. I have no idea if its setup the same as LS1 Edit or not. If not, then how do I obtain duty cycle on LS1 Edit?

 

the L76 intake will bolt up to which heads? L92 heads?

 

You gota lot of catching up to do. Several threads in this section you need to read. This has been covered long ago. But the answer to your question is yes.

 

Does the L76 intake flow as well as the LS7? The LS7 is only 60 bucks more, but I'm sure that there is some reason for your choosing the L76, just curious as to why. Any thoughts?

 

Also, will LS1/LS6 casting lifters, rockers, springs, retainers, and whatnot fit on the L92 casting?

 

This has been covered. Yes, except for the intake rockers which are L92 specific because they are offset.

I'm not sure, but if I took a guess, the LS7 flows better. If you opt for the LS7, then you'll need to use LS7 heads because they have their own unique port (location/type).

Now I just need to find someone who sells ported L92 for a decent price. I'm so glad that I didn't take the plunge and go with the FAST setup. I think I may give that new Holley throttle body a shot as well.

 

L92 heads + Patriot golds + valve job would probably do the trick. That'd be pretty cheap.

 

I think in a couple of months this set up (L92-L76) will be tried and true. I just wonder how speed shops, tuners, vendors will price this combo; let the PRICE WARS BEGIN!!!!!!!!!!

 

I am doing this swap on my 2000 ta 408 lme motor l96 heads l76 intake I was wandering if anybody done this and if all the acceries and wiring will hook up ---iron block 408 I would like some help please im waiting on my motor and would like to have everthing ready when it gets her in 2 weeks ----thanks for any input --old man spray!!

 

1500.00 will get you the set up only the the intake comes with drive by wire if you have cable you will need a fast or holley throttle body---new intake has 4 bolts 90 mil

 

since the ls3 is a 6.2 how different is it from the l92 truck engine?

cause the intake is suppose to be "higher" flowing\

curious if it'll fit on l92 heads
