I have been thinking of selling my car for a while due to the fact I hardly drive it so after sitting for a few months I started it and heard a whistle coming from the engine. My guess is one of the roller lifters is going away. Engine had steady 75psi oil pressure at cold idle and would increase to 80 with just slight rpm increase. I removed all belts and sounds still there. So unhooked battery down until repairs are made.

The decision is what I want to do now? In years past it would already be out but now after getting older and having a shoulder replacement I don't have that much desire to work on cars. Some people would just check the lash and replace lifters but I know me and I would probably end up stroking it and replacing a perfectly good rotating assembly. And then not drive it very much. Many options this is a factory 383 4 speed cuda,sell motor and replace? This is a stock bore hemi mega water block like the one on ebay that's up to $8100. Gen3? Easiest is to just do a refresh on a low mile engine.

Or do I discount it as is and then let someone else fix it the way they want? Some might want stock others a stroker? Just looking for impute.

Here's a couple of recent photo's.

Thanks Mike

If it were mine I would make the necessary repairs and then make my decision. I think you’re better off leaving it a hemi Cuda and if you don’t have time to enjoy the car right now maybe you will later.

Bad lifters whistle?

I'd be looking for a vacuum leak.

One way or the other, I'd try to fix it & drive it as much as possible.

iagree

I would start with a vacuum leak also.

Beautiful 'cuda. drool IMHO, a 383 just doesn't have the star power of a Hemi. I would have to fix it and drive it as is. boogie

But..... in the end, it is YOUR car. Do what makes you happy. up

I can't imagine having a Beast like that and not driving it.

I agree,
I would look closely at the vacuum plugs on the carbs. I have had multiple failures of these over the years. they will look just fine, but will leak.

mechanical roller lifters. Bearing in roller might be going bad. Sounds like bearing in alternator,or low power steering and carb leak. seems to becoming from center of engine. Started first looking for vacuum leak but even putting hand over both airhorns didn't change sound. Removing all vacuum and blocking them didn't help. Not much left to check unless the cam is eating fuel pump rod or cam button trying to eat through cover.

That's one pretty car.
My Street Hemi had a carb whistle years ago, it was kind of transient (basically at idle), went away after my guru pulled & re-jetted and re-rodded the carbs to work better with the low-vacuum cam in the motor.
Not saying the 2 were necessarily related, though.
To my ears, a carb/vacuum whistle is a decidedly different sound than an alternator or other bearing.
Grab a stethoscope or even a long socket extension and poke around.
I've never heard a roller lifter, solid or hydraulic, go away so I have no input on that, sorry.

Don't let it tip you over, just find it & fix it. Trust me on that, I get carried away and build monuments and make my life much harder than it needs to be.

I would at least define the problem BEFORE I made any decisions. It would be a shame to either heavily discount the car or do a major tear down over a vacuum leak or bad alternator bearing. That doesn't mean that you have to fix it, just that you really need to know the true extent of the problem.

And for cars that sit a lot, an Accusump or similar pre-luber can be a real engine saver.

Why stroke it? You've already got everything you need there for a streetable 9-10 second engine, stock stroke. If you need 500cid to make a 70 Cuda with a gen 2 Hemi move then you have no place around muscle cars. Its not a 440...

I've had all kinds ov weird, undiagnosable [censored] coming from my cars over the decades, i just drove 'em and they always sorted themselves out (not talking rod knocks here). In your case though... if it is bad, well... again, its not a 440...


By the way... absolutely wicked car man.

" I removed all belts and sounds still there. "

that takes the alternator out of the equation

I checked my records and should add that I had the oil pickup break in August 2017. I saw it loose pressure and shut it off. So I had the pan off and no metal in pan or filter. Everything looked good no noise. So in May of 2018 I drove it to a friends garage for storage while I finished my garage. Everything still good. Then in September 18 I picked it up drove home and only then did it start the noise.This was less than 3 miles. Thought it was vacuum leak so put it away for winter since I was in the middle of remodeling the house. I just got back to it thanks to all the rain and winter. There is very small glitter in oil now not magnetic after less than 30 miles since the pan was off. Either a lifter went away or a bearing got hurt by the broken pickup. Nothing on magnetic drain plug. One might not have anything to do with the other no way to ever know. For me anything less than pulling it and refreshing it would be a band aid. Others might disagree and that's ok I'd rather be safe. The good news is it's not destroyed or in need of anything much other than labor.

My records also show I bought the car in 12/09 put new zeroed dash in 8/11 and shows I've only driven it 2500 miles since. So maybe 3000 miles since I bought it! The reason I haven't taken it apart further is I know if I keep it it has to come out plus if I sell it it could be driven on trailer.

Just have to decide what to do.

Mike

Hey Mike,

Some would say, this is a good problem to have. That car is hot.

It's worth investigating for sure, but really smart to sit it in the corner and do a little soul searching
before making any kind of a move. If you're not physically feeling up to it anymore, and don't want someone else
doing it...then the answer is clear.

At the same time I'll say....the guys I know who keep going through various ailments and injuries, usually do it in small bites.
An hour or slightly more, here and there, only when the mood strikes.

The glitter may very well be from the bronze intermediate shaft gear. It's visible when I change my oil.

Good luck no matter your decision.

Rich

FIX IT then beat the snot out of it. drive

Nothing against building a stroker, but it wouldn't be that expensive to just freshen up the bottom end you already have, go through the heads, then get Dwayne to spec a good cam for the combo. Obviously I'd buy new lifters, springs, etc.

It'll always be worth more w/ the hemi in it. I think you'd get mad when guys start beating you up on the price if you try selling w/ it hurt...then you'd say to hell w/ it and fix it anyway.

Thanks for all the impute. Good points made by all. Rich a little at a time is good advise and Chip this is the first time ever you were worried about spending my money! Lol I would probably be replacing the rods another $2,000 for a stroker ain't no problem. Poor pictures but I can still see the crosshatch in the bores. I would just build what would be a fun lower maintenance hemi for this 3800# pig. As far as getting beat up on the price you ever try to buy something from a guy that doesn't need the money?

Complete waste ov money. Spend it on a (real) custom roller cam, or fuel injection, or an OD 5-speed or 6-speed. You'll be way ahead.

Amen to that! Have found taking it slow and easy still gets a lot done. P.S. keep the car - it's killer looking. wave

Maybe retorque the intake? Plenty of vacuum leaks possible there. Power brake booster, hose and valve. Troubleshoot the easy stuff before you start worrying. What a beautiful car!
