I have a 67 camaro with a 333 smallblock and a TH350 trans. The rear is a GM 10 bolt. Currently i have 4.10 gears installed. This is simply not working for me. In 3rd the engine is at 4500 RPM at 55mph. I watch my gass gauge just drop lol

I have to shift into 2 at around 10-15mph

what gears should i try. 3.23 3.55. 3.40

Plz help!

Not drag car, street use, hardly ever need to go on major highways. Most the time i am at 50-55mph

 

I think there is something else wrong with your setup. Perhaps your tranny is slipping, or your converter is too large/loose. With a guess of a 26" tire since you didnt specify, with the slippage of a non lockup converter you still shouldn't be but a hair over 3K rpm's @ 55MPH. I would start trouble shooting.

 

2800 RPM stall

17 wheels 245/45/17 tires (yes small)

what could be wrong. trans not slipping. Also have B&M shift kit.

 

opps not 4500 it was 3500 my mistake

 

Theres only so much you can do. 3500 isnt too bad, considering a smaller tire and what looks to be a fairly loose converter. A taller tire would help, although may not fit as far as looks go, or i would be looking for a better gear...3.55's or 3.73's would help drop the RPM's pretty well.

 

i am def changing the gears but idk what to!

should i go 3.20's 3.50's or 3.70's

 

tell me what you can live with for RPM at around 60, and if you plan on a different tire size.. and i will try to help.

 

2500-3000 max

tire are to stay same

thx alot BTW

mostly want to change b/c i have to shift outa 1st at 5-10 mph. that seems way off to me.

 

Depending on exact gear choices anything in the 3.4-3.5 area will work fine for your RPM requirements. Hope that helps.

 

okay will order ASAP

any brand better than others.
looking at richmond

 

Richmonds are said to be louder...but stronger then others. I don't necessarily believe that to be true. Proper setup will be the key to any gear lasting long and being quiet. Good luck.

I am not going to install them....buddy owes me for putting caddy lights in his S-10 lol

dotn care about sound, exhaust covers all! lol

I have richmond 4:10 in it now.

 

I have a '67 camaro with a 4speed muncie(4th is a 1:1 just like the auto) and i cruise 60mph at 3200rpm and i have 4.11 gears also. I love em. I went from a 3.08 to the 4.11 and i'm happy. maybe think about and overdrive unit for your auto.

 

how much is an overdrive unit for my trans. Is it worth it. I am on a budget....

 

check these calculators for the info you are looking for.
