They changed valves on a head for me and the new valves were too long i do not recommend also emailed them and got no response

Had my 5.7 hemi bored heads redone and bottom half assembled. I bent three valves on break in I sent joe an email he immediately called me asked what happened. I tore engine down took head back. He redone the head bought me another head gasket and did not charge another dime . Joe stands behind his work 100 percent. Engine has 2500 miles on and running strong. Thank you joe for your service !

Ive had Joe and his crew build me several motors . Both Automotive and Marine. They always perform better than expected and the turn around time was very quick

Great work, reasonable price and turn around time.

Joe and Chris are very knowledgeable and detail oriented machinists and engine builders. Joe will discuss your build in great detail and either use your parts or highly recommend a better quality part. Had a blower manifold milled and ported by them, beautiful work. Honest humble, knowledgeable and really build some super fast engines.

Awesome little place full of treasures. Walk through like a kid in a candy store

Amazing work and out of 20 years of supplying motors to the shop we never had one go bad.

Nice guys. Joe is easy to deal with and got my engine done quickly.

Joe built an iron block 408 for my c6 corvette in 2013, and in 2019 he built my 496 big block chevy for my chevelle. Hes a first class builder, and he keeps great communication. First class!

Theyve been been in business a long time. knowledgeable and honest

Finally a trust worthy shop in the automotive performance industry with integrity. Top notch race engine builder, or any engine platform at that. Import and domestic. Why use them for my LS7? Because Racecar!!!4 - digit hp builds regularly.Fixed LME’s junk

Experience, customer service, communication and the needs of the customer thats what you get with G&G.

Highly recommend... Joe and his team are top notch... No false promises or misleading information... Straight forward and honest about what will work and what doesnt!

Needed quick turnaround on a cylinder head valve job. These fellas ordered the valves I needed sight unseen over the phone and got the head rebuilt in 7 hours. Highly recommend.

Very knowledgeable business

These guys are the foremost best engine machinists in Houston. They handle all types of engine machining including sleeving.

Had a new z28 motor built by these jokers. Had issues the moment it was installed. Followed the owners advice and ended up pulling the motor out at with 3500 soft miles on the motor. Had a trusted motor builder tear it apart and we found that the new sleeves put in werent a matched set (different lengths). We pressure tested them and found 1/2 of them leaking. We paid for upgraded head gaskets, we found stock ones installed. I notified the owner and was basically blown off. STAY AWAY FROM THIS MOTOR BUILDER

Good work got my forged built block done here

Great on anything but coyote motors

Had a 396 ci small block all roller and ported 3 years ago wheel standing power no problems ever. getting ford motor built now

Fast, knowledgeable, and good prices!!! Vroom vroom!!

Great service
