65 365 car

I'm currently looking to buy a 65 365hp car, went and spent a half a day going over the car and I'm very pleased, ready to make an offer.

I could literally fire the car up and sit behind it and just listen to the exhaust, with that lumpy cam for hours.....It sounds that good!

One thing that bothers me is when the engine is revved up, the RPM's don't drop off immediately.. like I remember a solid lifter high revving V8 I had in the 1960's ( 289 K code 271 Ford)

I know with this motor the power comes in from 3500-6500 RPM But shouldn't it drop off faster when revved instead of ramping back slowly to idle?
Any thoughts and comments would be appreciated

That doesn't sound right to me. My 365 snaps back pretty quickly.

I'd check the throttle linkage for binding. With the engine off, just pull the arm all the way back and let it go. Sometimes it's a weak spring. Sometimes the ground strap screwed onto the arm is binding it up. I've also seen the carpet be a problem if it's jammed around the arm.

As to the flywheel, they were the same for all the small blocks in 1965 AFAIK. About 30 pounds.

Post a video clip so that we have something to reference against. Standard flywheels were used for all engines in all sizes and horsepower ratings. 33 pound nodular iron. The exceptions were the full race L88s of '67 - '69, which used light, 15 pound iron flywheels.

If the revs are hanging, then check for a binding throttle linkage or sticky distributor flyweights.
