Bought a 5.3 LS from Auto Store Studio. Got photos before shipping and the engine was exactly as described. Compression tested and runs perfectly. Could not be happier!

The 5.7 Hemi I ordered for my Ram 1500 arrived in 3 days. It was packaged extremely well and looked brand new inside. The 3-year warranty gave me peace of mind.

Carlos R.

Finding a clean 7.3 Powerstroke is tough. These guys had exactly what I needed, sent me photos within an hour, and it was at my shop in 4 days. Top notch service!

Dave W.
Ohio • 7.3 Powerstroke

Got a K24 for my Accord project. The engine had low miles and they sent a full compression test report. Dropped right in. Will buy from them again for sure.

Needed a 6.4 Hemi for my Challenger. The team was responsive and professional. Engine shipped fast and runs like new. Highly recommend Auto Store Studio.

Brandon S.
Georgia • 6.4 Hemi

The 5.0 Coyote I got was spotless. Real photos before purchase, honest communication, and fast delivery. Exactly what the automotive industry needs more of.
