Damn that thing is nasty, don't get mad when we run and I spray lol I thought you just put magnaflows on it, changed them again? Figured you would have already went speed density too.

I never had a doubt in my mind that your bottle would be on! Lol. I changed the mufflers because it was to quiet. I don't think any gains from the mufflers though. They both are straight through. The gains came from the pushrods (deflection) and the added vacuum. Maybe we can line them up later today! You game?

This thread is very interesting to me since we have a similar yet different combo ![Happy](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_stretch.gif)
Mine:
418
Prc 237's 115g valves
5/16 .080 push rods
254/260 .630/.625
1 3/4 stepped to 1 7/8
Super Vic with dominator TB
Loose verter backed by a glide
Last time on the dyno made 546/47x falling on its face at 6,650 due to float issues.
I am making the following changes:
Turned down ls3 valves
Powdered metal guides
Spring upgrade
1.85 roller rockers
Not sure if I will use a 5/16 .120 wall or a 3/8 .120 wall, what ever fits the heads
Moroso enhanced 4 vane vacuum pump
Porting the super Vic to line up with the heads, there is some core shift.
Being we were close before, it will be interesting to compare after results.

Man you have a pretty nasty combo, kind of max effort though. Just changing the pushrods to correct the float should surpass me. I could imagine yours with a 6speed would be very close to 600. Kinda hard to compare the two builds. I'm sure the victor would really shine on my build , I'm just not in to choping up my cowl and loosing street ability. Looking forward to seeing your results though! Could be very close to 600 thought an auto, good luck

Brennen,
I would say mine is a little more on the wilder side, but it is by no means extreme.
Your comment about the Super Vic, I was running it on my 347ci motor previously to the 418. I also had an 80e trans in it. Even if I short shifted 1-2 and locked the verter early, it still drove awesome. Switching from the ls6 to the super Vic, yes the dyno showed a loss of 10-15 till about 4,500, but I honestly did not feel it SOTP. Another thing, I had it idling fine with the ls6, but it is way easier to get a new combo to idle with the Super Vic. So the people that say drivability goes out the window, well, my guess is they haven't tried it!
Now with that said, I am not suggesting you chop up your car. We all build what we want to. I am just fortunate enough to have the room in my engine bay![Happy](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_stretch.gif)
I do think you would definately pick up power on the top end with a properly set up Super Vic.

Man I have to say its been very tempting to break out the metabo and start cutting away. I'm sure there would be substantial gains in the high rpm but I just can't make myself do it!
Lil SS you seem to have a really well working combo. It may even break 600 rwhp on the dyno once the changes are made. Either way I'm sure it hauls ***!! What vehicle is this in? Any times on it?
I'll be going speed density on the 16th. Geoff should be able to add the right amount of fuel after 6400. I don't really see me picking up any more Hrspwr although my map kpa was at 95 at wot. We will see. This should eliminate all restrictions. Hopefully everything goes well. Sadly I seem to be getting board with this setup. Do you see any area I change or improve apon without pulling heads? Btw nitrous will be next!!

So times are in my sig for the 546rwhp combo that was seeing valve train control issues.
This motor is in my pick up which is pictured in my avatar.

Ah I see, I use the mobile site 98% of the time.
I'm really digging your truck. Very nice times as well. What's it weigh in at? What size shot? Any plans on restoring it or plan to stay rat rodish?

So last time out it weighed 3,175 with me in it.
I have only used the first stage and it has a 52n jet in it, so around 100rwhp.
The plan is to rewire it do all the body work and do a wore out patina style paint job. Something similar to this:
