Gearing like a sports car

I took my 1965 140 out for a little ride today and noticed that it had nooooooo power in 1st, I’ve heard that in a normal 4 speed like mine 1st would top out at 37ish mine on the other hand topped out around 50-55 which worries me. I can barely start the car from a standstill and I don’t have the money for clutches to keep it this way. It does have some bigger wheels than stock (15 inch wheels tires I’d have too look at) but either way I need to change my gearing because as of right now the 1st is acting like second and fourth topped out is probably in the 200mph range and I ain’t lookin to stop from that with drums. This makes me think it has 3.08 gears as of right now, should I go down to 3.89 or even 4.10s?

15" wheels "could" be ok. Now, how about the tire size? Take a look, post the numbers. Stock Corvair is about 24 1/2 diameter.

I am guessing you probably have 3.27s and possibly a tuning or carburation issue?

My car does have a problem with starting off in 3rd because the linkage is looser than teens on prom night and that might have been it but Another thing is that I’m used to driving manual pickup trucks with way lower gears... so I might just be driving like an idiot. This is my first small manual car. And I know for a fact that my secondary’s are sucking air so that probably has a lot to do with it

Topping out at 50-55 is not 1st gear, 3rd sound way more like it.

Just so you know you'll never be going 200 mph.

3rd gear with a 3.55 rear end is good for about 80 mph, I think. 50-55 sounds like 2nd. I've 140 4 speeds with 3.55 and 3.27. Neither seemed sluggish.

Have to agree with others, don't think you were in first.

Wheel size has absolutely NOTHING to do with it. Doesn't matter if they are 13" or 18". It's tire size you need to pay attention to.

"I can barely start the car from a standstill and I don’t have the money for clutches" "should I go down to 3.89 or even 4.10s?"

If you don't have money for a new clutch where is the money coming from to purchase and install new gears???

"It does have some bigger wheels than stock (15 inch wheels tires I’d have too look at)"

As to wheel size that is basically a mote point. It is the diameter of the tire that is a factor. Something like a 225-75-15 will bog the car down though I doubt they could ever fit. I have 225-70-14's as temporary rollers on my EM and they barely fit.

"My car does have a problem with starting off in 3rd because the linkage is looser ..."

WHY would you even do that???

I think you need to evaluate the whole situation before considering a gear ratio change.

This is me hijacking the thread.

Well I really need to look at my Arrangement don't I?

My back wheels are running 215 60 r15. The fronts are nice, with 185 60 R14s, which I did to keep the wheels from rubbing. But I stuck the back with the bigger wheel and bigger tire cuz I thought it would work better at higher speeds. Myself, I'm shifting around 4,500 or 5000 and that puts my first gear and about 35 miles an hour, my second gear I can theoretically get to 55 but I'm always concerned that I'm revving too high.

So I guess my question is should I get smaller tires, and am I overly concerned about my revs?

F4U, I had an automatic 66 that was really sluggish on takeoff shortly after I got it. It turned out to be points that were barely opening. Jim

Eric, your rear tire size is fine and so is shifting at 5000.

With 3.27 gears and 23" tall tires my car is goes 47 mph in first, 69 in second, and 100 in third. It revs to 7,000 rpm though. Why are people afraid to rev to 5,000? Stock valve spring set up properly are good for 6,000.

No problem launching.

I was thinking (scary thought). If one of the primary carbs became disconnected, the car would be VERY sluggish to accelerate.

It’s not the car it’s the driver, I’m used to driving pickup trucks that will launch from idle, yes my secondary’s need some tuning but as of right now I just need to get used to driving a smaller car with higher gears. Sorry for the inconvenience and thanks for the help on the subject. Ultimately it was just my stupidity that was my downfall.

Since you say your shift linkage is loose I am guessing you started out in 3rd gear. Is reverse hard to find? You should service the shift linkage with new bushings in the tube and new couple/pin. The shifting in a 65 with correct and tight parts is very crisp and tight. You also state a secondary sucks air?? You need to give that some attention too because lean builds heat and heat causes seat ring failures in 4 carb engines.

If you generated a sig line with your location there may be someone close to you that would offer help and maybe parts. There are many here that lurk instead of posting. If they knew what town you lived in there may be someone very close to you. I also will ask if you are near a local club. Club members help each other a lot.

I’m from a small town in Utah called genola, I believe the closest club is way up north. But the car is a work in progress at the moment, I’ll get the secondary’s fixed and the linkage in due time.
