44cc Small block Hottie V8 engine This is my second engine directly from CISON. My first was the V2 15.7cc Harley Davidson Engine and now the Chevy small block V8. Both, I am very pleased with because both came directly from the manufacturer in China and the price compared to buying them in the U.S. is much cheaper directly from China. Customer service is absolutely great! I hope you are lucky enough to speak with Lucas! You can usually get a response very quickly. My experience has been within 24 hours! I first contacted CISON about a Hall sensor that went bad on my V2 engine. I had the sensor in my hand about 10 days later straight from China. My second experience was for instructions to assemble the V8 in English. I was immediately sent assembly instructions in Chinese that Lucas said would be converted to English and sent to me later. I actually converted the instructions to English and sent them back to CISON before they could do it! I simply used adobe to convert the document to word format in Chinese and then converted Chinese to English! They were very appreciative to me beating them to the punch. I am still in the process of assembling the V8 and will post videos to YouTube immediately when finished. These model engines are a real work of art and very mind blowing! Today I demonstrated the Harley Davidson engine to automotive students at my school and they were totally blown away that it actually runs..... myself and the instructor showed the partially assembled V8 engine to the students and they can't believe something that small and realistic actually work and runs! They wanted to hold the block! The price you pay for these engines is small compared to the WoW!!! you get from future automotive technicians. My plans are to purchase another one and donate it to the school. These things are great conversation pieces, fun to work on and even great to just look at! I love my purchases from CISON because they're trustworthy, reliable and better to purchase from than local. Stay tuned for my first videos on YouTube that will demonstrate problems, fixes and downloadable instructions in English. My first video will show what's in the box? Assembly and then running! Stay tuned...... I'll be back!

Just go ahead and pull the trigger! The ordering process was easy, tracking info was timely, and engine was packed carefully. I incorrectly thought a component was missing and contacted customer service. They quickly responded with directions to find the part in my kit. i am so happy with Engine DIY tgat I bought ANOTHER product from them!

Pleasure to do buisnes… I have had the pleasure to do buisnes with ENGINEDIY several times, never had any problems, very nice products and great service.

Great product-excellent fit and finish - superb service I was pleasantly surprised by the excellent fit and finish on this mini drill press. Very well made product. Was looking for a small tool to do some very tiny work on the deck of the boats I make and yet take up little space on the workbench. And this does it well. Well worth the price and love EngineDIY free shipping and fairly fast delivery to Canada - hassle free for sure. Had an issue with the power supply not included but the Customer Service came through and solved my problems immediately - Good Job!
