As mentioned before unsprung mass has a large effect on torque needed to turn the rear wheels, so if your new wheels are heavier than the stock c5 rims that is one area to consider. You also need to consider how the height of your new wheels and tires have effected your final drive ratio. Is your new rim and tire combination the same overall height as your old wheels? Not just in rim size, but actual tire height. Here's a better explanation of why that matters:

Thank you for the link. I get the idea now, but didn’t do the math. I obviously didn't realize that switching out the tires and wheels would have this effect;

It did turn it into a dog. I bought the C6 wheels and tires because they were an excellent deal and looked much better than my chrome plated wagon wheels. I had to basically give those wagons away, NOBODY WANTED THEM. The fun factor of smoking the tires is gone so I'm going to switch back to 18" wheels, although not wagons.
I'm going to take all of the factors and fit them into the outcome for the proper ones.
Again, thanks for the help.

 

I don't know what your budget is, but there are tons of ways bump your power output. The sky is limit with this platform....or at least your wallet. A full exhaust system (header, X pipe, catback) and a tune would put you ahead on power and sound. For that matter if your exhaust is stock, just a catcback system might improve your driving enjoyment enough to forget about the slight power loss. Or if you want a massive bump in power, start looking into a cam swap. Another option would be to swap your rear axle gear for a different ratio unit to suit your needs better like the article mentions. There are multiple ways around the issue. If I was really attached to the new wheels I would look into another solution.

 

When I was a kid I had a Charger 500/426 HEMI 456 rear end, not a high top speed (we actually knew what a HEMI was) which in 69 they only made 500. Most were probably 440 MAGNUM. My Charger had headers/glass pack mufflers (remember those, if you are old enough) that was the exhaust. I didn’t have to worry about x pipes, or y pipes or any pipes, it had no pipes.

I had to keep moving because those exhaust outlets were a little close to the place where people needed to breathe.
That’s all I knew about cars.
Cables, real cables, pulled on things, they had roll up windows, adjust the mirrors manually moving them by hand, which was hard to do on the passenger side. Things you could see, a HEMI, spark plugs right through the top of the heads, dual quads. Not covered by plastic so you don't even know what the engine looks like.

Now, computers………… everything else that you can think of, and that’s a 98.
You don’t even need to drive a car now; the driver is just the back-up for everything else.
I have no idea what anything costs or even the expertise to change a belt. Maybe if I ran 70 PSI in the rear tires it may squeak when it hits 2nd gear.
So, what would a cam and installation cost?
Maybe I should put this thing in the crusher and wait until I’m 120 years old and get a C9.
I'll only drive that one 1K a year as well.

 

what is a rotflmao?

 

I'm apparently in your age group since I also remember and had a 426 Hemi, in addition to other cars, but I'll follow your Chrysler lead. I also remember glass packs with the Cherry Bomb probably being the most common.

While the old school part of me dislikes computers and prefers "the old days", you'll find your "computerized" 346ci, 345hp, 1998 Corvette gives up 80 cubic inches and 105hp to the 1969 Hemi but is the same or slightly faster both to 60mph and in the quarter mile than a commonly configured 1969 450hp Charger. With 4.56 gears you’re going to accelerate quicker, at the expense of top speed, and would max out about 20-25mph less than the Corvette. As much fun as it is going fast, stopping can often times be even more important. Comparing the two cars, the Vette will stop from 80mph about 70’ sooner than the Charger. To me, that’s a critical distance disparity. And gas mileage? Your Vette will be 2-3 times more efficient than the old Charger.

As I’m sure you remember, you could see the spark plugs in the top of the heads due to the hemispherical head which provided a more efficient combustion chamber because of the minimal heat loss in the head and the ability to use larger valves since they were opposite each other rather than side by side. Especially in its cross-ram carburetor setup, I believe the Hemi is still one of the most impressive appearing engines.

“So, what would a cam and installation cost?” There is a vendor here on the Forum who has a $2500 cam package. I can’t remember the business name (I’m sure one of our members will quickly provide this info). If I recall correctly the package included a choice of cams, replacement valve springs, timing chain, push rods, crank bolt, spark plugs, all the seals/gaskets needed to close the engine back up, as well as dyno tune. I believe there may have also been a new oil pump, but right now the business name has escaped my memory.

If you decide to put your Vette into a crusher, I'm sure you'll find many members here very willing to get the car out of your hair (myself included).

 

I'VE CHANGED MY MIND again, NO CRUSHER

Yea, I've seen TV shows about the old time MUSCLE CARS and they really aren't very impressive. MUSCLE sounds cool.
It sure was easy to change plugs on that HEMI. 426 HEMI, just sounds cool.

The carbs were one in front of the other on the 69 Charger 500.
I've seen the set-up you’re talking about but not the way this one was. The intake manifold and carb configuration were not modified. They were just like new, except the car had the **** beat out of it and wasn’t like new. HMM, I wonder why?
I was a kid, maybe 17, got my license about 16 back in the olden days, I think. When I got in and pushed the pedal to the floor in the Charger, it sure did seem fast.
After listening and thinking about the explanations (and thank you guys for the ideas) after further thought I think the gear ratio with the taller wheels is the issue. Maybe that's what it is all about? I may have been told that already but I didn't go back and read everything, I’m in ill health (that’s what I tell everybody). So the real way to get back to the lost acceleration, if I keep there 19" wheels, is to change the gears from its present 315.
My wife "NOW YOU WANT TO SPEND HOW MUCH FOR WHAT?" I need to consider the “WIFE FACTOR” here. What do ya think?

In addition, I would like to mention;

I survived the WIDOWMAKER a few weeks ago. They went in , stuck a wire in my heart, all better now, but you should all feel sorry for me.

I believe that everybody should put the $ together to pay for my car. , it would be the right thing to do.

 

This was the configuration of the
426 hemi in my 69 Charger 500,
carbs, 1 in front of the other
Completely stock 100% rebuilt= 491hp on a dyno
