VF500f motor ?

Should fit OK but be down on power as it used different cams, carbs and port sizes if it's anything like most Honda 'customs' (they get tuned for torque)
 
This is what else I've found while looking a round alittle. Actually says They're the same for the most part... This is good news. Think I might be piecing a fun bike together for cheap...

The Honda VF500 is one of Honda's second generation V4 motorcycle engines produced in a series of motorcycles designated with VF and VFR initials. For 1984-1986, Honda produced the 498 cc, V4 DOHC VF500 for the VF500C Magna V30 and its sister bike, the VF500F. This engine is an evolution of Honda's original domestic market 400 cc engine, originally deemed too small and underpowered for certain markets - notably the United States and Europe. Focusing on adding power and versatility to its motorcycle offerings, Honda bored the original 400 cc motor and improved its power and performance. The engine is almost entirely identical to the version in the Interceptor VF500F sport bike, and while Honda sold the VF500C Magna in the United States, it advertised it as the "most powerful midsize custom in the world".[8]
This standard motorcycle was introduced as a balanced bike that was just as enjoyable yet easier to ride in town than its larger Magna siblings, with good power and a broad torque band. Thanks to its V4 design, power in the 500 engine is not peaky and ample torque can be found throughout the rev band, and the six speed transmission ratio was unique to this bike versus the ratio on the VF500F.[9] The engine produced between 64-68 horsepower, and combined with its low weight and low center of gravity, the bike was lauded by critics as an easy to ride and entertaining motorcycle.[9]
The Magna had no shaft drive like its larger siblings, but a traditional chain drive.[9]
Specifications:
Standing-start quarter mile - 12.9 sec at 103 mph
0-60 in 3.9 seconds


The tranny gearing should be easy to swap since if this deal happens I'll have 2 motors. 1 stock 100% complete VF500F interceptor motor (seized) and 1 good magna motor.
 
Good luck with it.
Generally I hate the V-4 Honda's but the 400/500 gave less problems than the bigger motors, were lighter and handled pretty good so I'm sorta OK with them ;)
 
Thanks for your responses PJ. The hp rating that I keep finding is a little higher than the above Iposted last night. I am finding info alot closer and around 70 hp..? Is that correct ya think? Factory dry weight is 402lbs... I figure one could get rid of 20-30lbs of that... And if they are indeed 70 hp that would equal plenty of fun IMO. I know the 80's repli racer is popular right now, and I think one of these would make a great one! The performance reviews on these machines was pretty positive.
 
I think it was only the VF500R that claimed 70bhp?
Probably closer to 55 at wheel though, the Japanese used pit ponies instead of horses back then ;)
