I had a 6-8psi pulley on my LT1. I’m basically just doing a sloppy build so keeping crank, pistons/rods original. Will stay in the 6k rpm range and boost level that gets me to my goal.

Plus not like any of those clapped outlaws are street cars anyways, nor are they anywhere near the fastest. I wish they didnt get approval, show is AIDS. Makes everyone with a modified car look like a podunk hillbilly fkn his cousin.

Just so I’m understanding you guys correctly. My 5.3 LM7 build won’t be anything for over 500rwhp-600rwhp that’s the plan. Now it’s not going to be a strip car either just a weekend warrior and think I will go the blower route again like my original LT1 had. This is a LS swap into my 1994z28. Just want some nice power out of it. Had Vortech in the past so might go with Procharger this time not sure yet but everyone has always said cranks must be pinned.. I only had maybe 200miles on my camaro but also didn’t beat on it. But the tuner screwed up the engine anyhow. My question is I don’t need to pin my crank? I don’t know how high I’m going to be rev the engine but you see my hp goal. Not trying to be off topic just asking if the crank pin is really needed or mainly just for a race car... Budget build so not wanting to spend what I won’t need. Thanks guys.
From what I've learned, you have no need for a crank pin kit at that power level.....but I'm still learning about this shiiiii---stuff......

I guess it wouldn’t hurt so it though for safety and if down the line I boost up... I read even some NA guys get it done.

Someone upthread mentioned a single twin scroll turbo with the dual V-band inlet to reduce packaging size. Those are neat. How much power can you get from one?
I didn't even know such a thing existed until this thread, and my first search showed me a GTX3584RS... which is a nice turbo for a daily driver, but not what the OP is looking for.

Definitely will and a ATI damper and bolt. Your engine looks nice and clean. Need to scrub mine down pretty soon. Also see your extra support for the engine stand what made you decide to do that?

GT55 turbo...supposed to support 1,900 HP.....it should fit my turbo kit with a little massaging, just slightly larger outer dimensions as the S400 chassis.
The S400 chassis now has a 91/104 stuffed inside it. that now has 92/104 internals. Supposed to support 1,300-1,400 HP.
What cubic inch would be best for the GT55....? No Lag......fast spool.

If whoever is doing your tune cant get a 390 or 427 to lightoff a GT55 quickly they shouldn't be tuning it. I have 5.3’s huffing 25psi in a second and a half and thats on a slow boost ramp to get it to hook.

Ya the 91 works but its pretty tapped out by 12-1300. I’d rather have an 88mm GT55 with its 112mm turbine on that cubic inch then a 91 S400 with the 104.

Top end is plenty, 160 isnt a problem, it should trap higher then that in the 1/4 on fairly low boost.
