Dear Old Friend,
Are you curious about the exciting news we're about to unveil today? Well, hold onto your hats, because at the end of this month, we're launching not one, but two impressive V8 engine kits. You'll have your pick between the flathead and OHV versions.
I vividly recall the moment our team decided to venture into the world of engine model craftsmanship over a decade ago. Time has flown by since then. Throughout this journey, we've borne witness to the rapid evolution of the model engine industry. Collaborating with numerous esteemed engine engineers and contending with a growing field of competitors, we've steadily gained recognition among engine hobbyists, all thanks to our unwavering commitment to professionalism.
We've often pondered: what makes the perfect engine? Which engine model truly resonates with users? Fortunately, we've received invaluable advice from numerous professional engine enthusiasts. Their insights have propelled us to continually refine our engine production technology, and this dedication has led us to where we stand today. At the beginning of 2022, we released two Cison in-line four-cylinder engine kits, the CISON FL4-175 Flathead and OHV series. Fortunately, they were loved by everyone as soon as they were launched. This gives me confidence to add the v8 engine model into Cison engine lineup. Amidst the myriad engine series available, you may have encountered various V8 engines, in my opinion, each one possessing its own distinct allure just like every diamond.
CISON FL4-175 Flathead and OHV series
Our team has always aspired to craft a genuine V8 engine – one that elicits a beaming smile and prompts you to exclaim, "Yes, this is the engine I've been yearning for." Today marks the very first time we're revealing information about this exceptional creation. For the past year, we've kept it under wraps, focusing our efforts on meticulous research and development. The prototypes alone set us back nearly $100,000, a testament to our unwavering commitment to delivering the finest V8 engine model in our repertoire, both in terms of design fidelity and manufacturing excellence.
We dedicated a full year to designing a V8 engine inspired by the timeless American style small block series that has left an indelible mark on the history of American V8 engines. Our design philosophy centers on faithfully restoring the engine's authentic appearance to the greatest extent possible.
We hope you can truly sense the depth of sincerity embodied by our dedicated engineering team.
I will appreciate it very much if you can tell me what do you think of these engines. Something like color, design, and so on.

AWESOME!! this is what we have wanted all along. The Cison engines are well engineered and reliable please put my name on one to show the world on my YouTube channel
Make the small block one first that would be cool
I would love to see the flathead version first!
Looks fantastic!! Brings back memories of the 283 small block in my 63’ Chevy Belair!
Let me know when the OHV small block is ready for sale
Make the Flathead version first. That looks like a real winner. We made 40 of these engines in a larger size and sold them instantly. Email me when you get the first one done. Thanks Remy Haynes
