I was wondering what happens when I put 3.42 gears in the Th350 tranny what is going to be the rpm at 65?

 

My 1969 SCCA Camaro is set up that way.
3.42 is great for 3 speed Turbo-350 automatic.
45mph = 2500 estimate
65mph = 2850, with 70mph coming in around 3000.
I'm running about 330 hp @the flywheel; Auburn
posi on 10 bolt. The rides great on short road coures. Hope that helps! <img border="0" title="" alt="[Cool]" src="gr_images/icons/cool.gif" />

 

Mistake:
45mph = 2000 rpm

Sorry.

 

I got 3.73's w/a moser 12-bolt...

45mph = 2300rpm

60mph = 3000 rpm

I have a 3600 stall too... <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

 

what hears do I have if my rpm is

65=3000

 

what hears do I have if my rpm is

65=3000

I want to race.

 

sorry

hears= gears

 

Might be a 3.42

 

Some guy said it might be a 2.73 but I think you guys know more than he does. When I punch it you can feel the power at 3000 and after why is that?

 

Well my car cruises at 3000 at 60mph, and I have 3.73's, if you had 2.73's it would be A LOT lower at 65 mph..

 

Hey its me mcj at friends house. Well the gears came out of a 86 V-6 firebird, and I think my speed was at 65 becuz my speedometer does not work, and it was next to my fiends 98 camaro and his said 65, and my rpm was at 3000

 

Don't worry when you see ChrisG talking in this when it is about me its me at his house. I just write there so I can give time to respond by the time I get home.
