i went back and didnt see a Fast on the list. I just saw mention of the ported stocker which gained 1hp. Then saw the 8hp gain from the heads. The interesting part of this is the fact that 1hp gained with the ported intake gives you a window into how much air the head is moving. You could probably reverse engineer some flow #'s of a stock intake flowed on a stock or ported stock 823 head and look at where the .550-.600#'s are and guesstimate that is actually how much is getting used when the valve is open. Maybe
You can see in the pictures and dyno video that he had the FAST intake on.
Post #9 has great comparable flow details of a rod modded LS3 intake.
You'll want a ~5500-6000 stall converter for the big boy there haha. It'll be fine on the dyno obviously just to learn what it does.
I'd actually think you're going to want to keep the long runner intake for the big cam that IVC is pretty late for a short stroke engine.
With a victor jr single plane a 239/251 on 110+2 cam did amazing in a SBE ls3. Similar overlap as your big cam, but way different valve events. Peaked at ~7400. Chassis dyno number isn't amazing, but that's through a 10 bolt, 6000 stall converter and powerglide on slicks. It did work on track we went a best of 10.13 at 131-ish at a slow track in our '80 malibu station wagon. That was such a fun engine. One of the flycut pistons let go at 750 runs.
2nd pull with the stage 4 cam today . 11.8 afr and only like 23* . Had a catastrophic failure on decel after this pull. Well go into details tomorrow ! Big cam and e85 really woke it up.. there was ALOT left lol

Sorry to hear that, hope you can get it back in action soon. What happened, rod let go? There is a complete L92 in the classified that just got listed if you need a core.

In the previous post it was REV solid stainless steel valves and if it dropped a valve.
They werent Rev intake Valves. I just got back from dropping the heads off to Hooper. He used a different brand. Hes currently recalling the sets he used these valves on . I'll be getting another set of heads in a week or 2
Ordered them exactly how he sells them. With the rev valves

Exactly why I asked this, although your saying he didn’t put REV in yours. After the dust settles, I’d be interested in knowing what valve he used in yours.
F$ck that sucks. Sorry, man. If you need help finding a block LMK. I have a couple sources. Honestly, if it's in the budget, I would get a Dart Alum or sleeve a stock block. If you are building, then build all the way.

I thought he put rev valves in it. But I was mistaken
