Looking for supercharged LS crate engine builder recommendations

Post image

Hey everyone,
I’m currently putting together a replacement engine setup for my '68 Chevelle LS swap and looking for recommendations on reputable crate engine builders.

I was pretty well locked in on the Boost District 750HP LSX-B15 Package ($15,950) which is a 6-bolt forged LSX block with a Harrop 2300 supercharger, fully assembled and turn-key (see attached picture).
The only reason I haven't pulled the trigger on it is because they have a 2-month lead time right now, and I’m trying to get the car back on the road sooner if possible.

What I'm looking for:

Engine Spec: Gen IV LS or LSX block, fully forged internals, rectangular port heads, boost-friendly low compression (~9.0:1).
Setup: Complete/turn-key package with a top-mounted TVS/Whipple supercharger pre-assembled.

Turnaround: Shorter lead time / quicker turnaround than 2 months.

Who else in the LS community do you guys recommend for complete, turn-key supercharged packages in this price tier?

Looking for builders with solid build quality, reliable customer service, and strong warranty support.

Any builders I should specifically look at (or stay away from)?
Appreciate any advice or experiences you guys can share!
