What he said!

Everyone's different, I got spoiled to a 6 speed manual Cobra mustang with a Kenne Bell intercooled supercharger that would float down the highway at 1900 RPM's. Had nothing to do with a neutered family sedan lol. I like to enjoy new technology, just can't afford an overdrive right now. My eventual goal will be to drive down the highway at a comfortable level, run a 10.90 and drive home, I already have the horsepower. High RPM on the highway is annoying to me, but not to everybody, and I've had some 9 sec cars.

I don't think anything's wrong with my 9.5, I'm just being picky, I've talked to Dynamic, it's setup as tight as they can make it going by the serial number and it is not slipping excessively, I just know that it would be more enjoyable for me to drive if the RPM's were lower.

I'll try the 3.23's first, if that's not quite enough I'll stick a tight converter in it.
Thanks for all the input guys!!

My Charger has 4.10:1 Strange 60 with spool and a tight 9" converter from Ultimate. The converter is so tight you would think it was a stock 11" converter till you punch the throttle then it flashes to 5,000 rpm. Really don't notice any slippage under normal light throttle driving.

I've always heard good things about Ultimate converters, but it would most likely slip a little bit if you put some 3.23 gears in there.

I switched from 3.55's to 3.23's years ago and never looked back. When I'm on the highway, I want to be able to keep up with the traffic flow (generally 70 to 80 MPH around here) without excessively high RPMs.

I wonder how many guys cars I could take, add some good sound deadener to the floor, firewall and trunk, unhook the tach and tell them I put in an overdrive! Seeing the number on the tach is what does it for most of us.

And tailpipes!

I agree the noise is what wares on you. I had a 79 trans am with a 4 speed 3.23. It was nice on the highway. Plesent on a trip. I traded it in on 1979 corvette l82 4 speed with 3.73's. It was fun on the back roads but not half as good on the road as the trans am. Before the trans am I had 1970 442 olds w30 with auto and 3.23 it was factory air car. It was also great road car. I would do some insulating and add out the back turn down tailpipes. I would use 2.5 tailpipes mandrel bent. The exhaust has cooled enough by the time it's made its way through the mufflers for the 2.5 tails not to hurt you much. The F. A. S. T cars do it through a full 2.5. That along with the 3.23 I believe will fix you if your converter is tight enough.

My humpster has a 3.15 ratio with a 27.5" tall tire. It's happy at 60, 65.
It'll actually get mid-teens for mileage if you keep it around that speed. Running 70, 75 will get you there quicker but will slurp up the fuel in no time.

My Gremlin has a 3.08 rear and no overdrive (yet!). The little half-dozen is generally buzzin' around 2,500 out on the highway around 60. That car is the most fun to drive. At 60, it's still got plenty of go left. If you need to pass, just leave it in 3rd, and walk on it. It just wakes up and goes around whatever you wanted to pass.

Love that little six!

This.

Fix the exhaust first. The 2 1/2 tails will be quieter and might actually make as much or more power as 3". If there is room you could add some straight thru bullets in the tailpipes to make it even quieter and help eliminate possible drone problems.

If you want to try some converters I have 11" out of a 69 Superbee and a never been used 10" Fairbanks that is old enough that it was probably built by Lupo before he started Dynamic.

Thanks GoMango, I sent you a PM.

Thats just how my 9.5 dynamic converter works for me. I never notice any slipping or high rpm cruising. At the track when I hit it the flash is right about 4200 what I wanted. Its their 9.5 street/strip converter and I have had in in my 63 since 2006. I can cruise in third at 2000 rpm all day and it sounds normal to me. Its never ran hot or gave any trouble and I drive it alot.
I also do understand how eng noise and rpm can trick people as I remember all the complaints we used to get at the dealer when people said the trans was not shifting into third because of the noise from the fan clutch. And when the fan clutch did come back on it really sounded different even though nothing changed in the eng rpm. Ron

I currently use 4.10s and short tires 25 inch tall on the 360 I have run for years 4.30s or even 4.56s with 28 tall tires Helps keep the engine cleaned out after a lot of very short trips Lowest I have run now is 3.91s do you get passed on interstate Yes but the cops will not be bothering you at 60-65 mph. My one car is B-3 and it does stick out on the road

This is exactly 100% correct. Unhook the tach. That engine is loving that RPM range. It's ain't hurting a thing.

My car has 4.56's and 27.5 tires. I drive it down the FW at 70 and it turns....well I'm not exactly sure because I don't care. I'd say it's 3800. Some day I'll look.

I've been doing this since 1981 when my first DD street car got 4.56's. The gears paid for themselves in one weekend. Hell, I may go to 4.88's in the future.

LOL, I already know there's nothing wrong with my car or converter, like I've already mentioned many times, it's just personal preference. Tailpipes and sound deadeners don't fix RPM, just covers it up.
I drive this thing alot and I do not enjoy high RPM with a Prius blowing by me, I want to have alot of gear left in case I need to show someone these taillights.
