Flag Motorsports

An amazing shop that is overqualified and did an amazing job on my LS3 short block rebuild. I drove 9 hours to drop my block off at the shop and am very pleased with the work and price. Above all, the communication while it was in the shop was great which is very hard to find. Thank you Flag!!!

Ever heard of no replacement for displacement? Flag can prove it. I am no new comer to fast cars and powerful engines but my new motor blew me away. It was beyond any and all expectations I had (and I had a lot). They have built me a 427 LS3 that makes 604WHP on 93 pump gas. Did I mention its reliable? Did I mention the powerband might as well start at 1k? Thats how it feels. This however does not actually explain or cover what is so magical about Flag Motorsports. From the moment we were in contact, they worked extremely closely with me to get me exactly what I needed for what I can afford. Every step of the way, every detail, every question, they made sure we were on the same page. You would think that after I received the motor and they received payment, the transaction was complete. That couldn't be further from the truth. They followed up with me multiple times to make sure everything was good. I had multiple questions about best practices and they were so fast to answer. Even if they were unsure, they found the answer. The bottomline is, great parts are great parts. Great quality is great quality. Results are results. However, caring, compassion, integrity, and dedication are far more rare than everything else. Do business with them and you will get to first hand experience all of those. It was a breath of fresh air compared to the typical experience.

I was looking for a high quality LS engine for my classic car project and contacted Flag Motorsports. I've always liked the thicker sleeves that an LS2 block has, so we settled on a fully forged rotating assembly in an LS2 with high quality valve train and shaft rocker arms for strength and durability. I wanted a totally blacked out engine package, but with some silver accents as my car is silver. Flag worked with me to select a Holley accessory drive with an atomic intake and their really nice billet valve covers. They also got me set up with a brand new T-56 magnum transmission. I am really happy with how the engine looks and how well the accessories and everything came together and I can't wait to get the rest of my car finished to drive this! Big thanks to the team at Flag Motorsports for my killer engine!!

I shipped my car to California to have the TCI frame installed and a ls3 and Tremec 6 speed. Through this process I met Nicole and Evan with Flag Motorsports. I have one of their builds in my 71 Camaro nicknamed “Cracker”. It took me 10 months after getting the car back to make it what I wanted and all this time I was in communication with Nicole and Evan. My first time on track was in Cracker at the Apex hpde at MSR Cresson, in Cresson TX. From the very first corner drivingit in anger I knew I had something special. The power and smoothness, and to be honest the feeling that my motor is indestructible, is badass. Nicole has been so calm for a caveman like me, I once called them from an O’reillys because they didn’t have the right engine oil, Evan helped me get the right oil and the next day I was again driving Cracker in anger. I’d def buy another engine from these two, they are forthcoming with data and were a solid foundation to build my dream car on. Thanks again You’All.

I had the pleasure of working with Flag Motorsports after my GM crate motor failed in my E46 competition drift car. Despite only having made it through 11 events, the engine spun a rod bearing, and I was in need of a reliable rebuild. I sent them a short video of the engine's symptoms, and they quickly diagnosed the issue, pinpointing the spun rod bearing with incredible precision. Their expertise was immediately evident. Flag Motorsports not only rebuilt my LS3 engine but also transformed it into a stroker engine, significantly increasing its performance. The team was meticulous in their work, paying close attention to every detail during the rebuild process. The final product is an absolute beast—smooth, responsive, and ready to handle the extreme demands of competition drifting. The engine now runs like a dream, delivering more power and torque than ever before. It’s clear that Flag Motorsports takes pride in their work, and their ability to diagnose and rebuild engines with such skill is a testament to their expertise. I couldn’t be happier with the outcome, and I highly recommend Flag Motorsports to anyone looking for top-notch LS engine builds or rebuilds.
