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.

I would like a flathead version !
Will do a duel carb set up for the ohv make it an option and a blower set up
The overhead valve version is supposed to be a Rover engine. It looks like one, especially the distributor location and oil pan. However, the Rover engine is all aluminum, unpainted, so I would like to see an aluminum-colored overhead valve engine.
I prefer the Ford side valve version but depends on the price between the two
I like the overhead valve design. The gold color is very good. Black would be good too.
I definitely prefer the V8 OHV version in red or gold. I have the L4-175 and I love it. Hopefully the V8 will be as good if not better than the 4 cylinder. Ive been watching every video you have released and am excited to see the final version.
What price for flat head engine and price for hov engine vir generator and all
Both look amazing, but I’d probably go for the OHV engine. Please let us know what comes with the engine and what will cost extra. The Cison V8 looks like a work of art and I look forward to buying one.
I prefer the Orange OHV version. I would like a more complete kit with radiator, stand, exhaust manifold, spark-plugs etc.
Beautifull design! I would definitely choose the OHV version over the flathead. On color, I like the “pearlite” red as it makes the engine pop. Although the flat red is more in line with the old school muscle car V8’s. I like the intake manifold too. Any chance a high-rise Edelbrock type manifold is in the works? Maybe a root blower and scoop!
