Whether you are a die-hard Evo fan or a loyal Twin Cam rider, this article will provide an informative and unbiased comparison between these iconic engines. Here, we will delve into Harley Evo vs Twin Cam, analyzing their design, performance, and overall impact on the Harley-Davidson legacy. The Evolution (Evo) engine, introduced in 1984, significantly improved over its predecessor, the Shovelhead engine. However, one debate that has sparked up among Harley enthusiasts is comparing the Evo and Twin Cam engines. With a rich history and a loyal following, Harley-Davidson has continuously evolved its engines to suit the changing demands of its riders. Producing strong low and mid range power.Harley-Davidson, the iconic American motorcycle brand, has produced legendary bikes for over a century. An Excellent compromise between the 525 and 574 achieving the best all around performance. Wicked power band for 103 and larger engines. ![]() Respondes well to head work and increased compression. Go to bolt in camshaft for 110 engines.įreight train pulling power. Works best with larger displacement engines and added compression. ![]() Will respond well to ported heads and open intake. Requires high lift valve springs.Įye blurring mid and top end power. Requires high lift valve springs.īolt in. We know that the lesser the cam, the higher the pushrod angle. Wide powerband throughout the entire RPM range when compared to stock. So Evo engines have higher pushrod angles because of having one cam. Will respond well with slip-on mufflers and a high flow air cleaner.īolt-in. Best all around camshaft, Feuling's go to especially in 4 3/8 stroke. Solid bottom end with substantial gains above 2,800 RPM when compared to stock. Responds well to increased bore and or compressionīolt-in. Great all around camshaft, Feuling's go to for 4 1/2 stroke 114" & 117" looking for a little more than our 465 grind. Responds very well to increased bore and or compression Great bottom end with substantial gains above 2,800 RPM when compared to stock. Shines in 114 + cubic inch engines with added compression. The 508 revs up faster than the 521 grind, sounds nastier and pulls harder out of the hole. Shines in 114 and larger engines with increased compression. Easier to tune, better street manners & revs up higher than the 508. Shines in 124 + cubic inch engines with added compression. "The Big Nasty" Get serious with bore size, ported cylinder heads & throttle body.Ĭylinder head & intake work + high flow throttle body & performance exhaust recommended. Aggressive camshaft requires performance pushrods, lifters, high flow air cleaner, stepped exhaust and high lift/high load valve springs (See #1207).īolt in for Evo engines. Just like SS, Andrews, SE, or whatever other camshafts are out there. Will respond well to increased compression and cylinder head work. Wood Cams are the best camshafts money can buy. The short duration, extremely high lift profile he runs is stupid powerful. Will respond well to increased compression and head work. I have always used ev27 cams as it seems like the best all around riding cam. Increased compression is required for bottom end performance. If your looking for more torque restrict the exhaust to add some back pressure. I suggest dropping the exhaust and adding some power cones instaed of muffling the sound of your pipes with baffles. This is a great all around camshaft for engines with increased compression ratio, produces solid low end performance and mind blowing mid and top end power. ![]() To Place Orders by Phone 7AM-5PM Central Call Toll-Free 1-80 Give Operator Referral 1230864 for fastest shipping If you have any questions please contact. Requires high lift valve springs, adjustable pushrods, increased compression, head work, perforamnce exhaust and intake. Recommend using with larger displacement.
