Single or twins with lsx 427 I've searched on here and i'm trying to figure out what's the best setup for a built lsx 427. The lsx build will consist of a drangon slayer crank, callies rods, diamond pistons with coated skirts set .300 down. The setup is going in a GMC Syclone and will be awd also with a built 4l80e behind it. So right now I have a brand new dbb 88mm turbo with a t4 housing. Is the 88 to big to small? I've tried to research and for the 427 what's better a single turbo kit or a twin turbo kit? The truck will be mainly a street car with the occasional pass down the track.
If a single turbo kits is good what size? Is the 88 to small?
If a twin kit is the best idea what size twins? 67? 35rs?

a T4 88mm turbo is too small for 427ci.
I would do a 98-106mm single with a T6 1.32 housing or 2 76-80mm with small T4 exh a/r

Shawn,
I'm probably going to run the trick flow gen x heads a far as an intake manifold I'm not sure yet. Rpm range an power wise I'm not sure. I want it to be a fun street truck. I know I want to atleats be in the 700-900 range I'm thinking that's pretty realistic. Correct?
A single setup would def be cheaper to build but will a twin setup be better for the street? Is a 91mm pro billet set a good choice for a single?

A 91mm single would be fine with the proper exhaust housing,most people like to over turbo motors for some reason.I would rather run a small turbo that make alot of low end power-i think the philosophy is instead of figuring out how to make the engine more efficient-just add more boost.

Verdad Gallardo twin's may be more "fun" on the street if getting loose is the game (gobs of instant torque). But if you want to win races, I'd recommend a single. The 427 will be plenty torquey on it's own all ready. a little lag and a good boost controller will make it more manageable on the street. Honestly though, you'll probably have big traction problems regardless with that many cubes and a turbo.
But here is the million dollar question, why 427 ci for a street truck?

for a single-a 91mm with a t6 1.0 ar turbine housing.This will make for quick spoolup while still making great top end power.The t4 flange is too small for that cubic inch

Why a 427? Bc for me it was the sane price to build a 427 as it was to build a 408 or 416. And I def wanted to run the lsx block over the lq9 bc for the piece of mind that no matter what setup I put in it I had enough bottom end to cover it.
So either one 91mm or twin 67s or 70s. Would that be the general opinion?
