On the locker rear ends, is it bad to put one in a daily driver(as far as wear is concerned)? seeing that they pop in and out as one wheel spins faster than the other will I damage it driving everyday? thanks..

No, H8, you won't damage it by driving it on the street. However, a lot of folks don't care for them on the street because of the loud clicking noise  they make when you turn a corner. I figure I know what the noise is, so "it's a good thing"....  Ryan

The noise is why the 66 GT-350s didn't have them standard. People are afraid of what they don't understand.  ------------------

I like the sound of mine! Nothing like a tight rear end! Music to my ears. DL's behave acceptably on the street, but you gotta be careful on wet streets! That tight rear end will loosen up and swing aroud quick! Brian

Since we are on the subject, can you guys explain the ratio on rear ends, I think my 66 289 came with a 2.79:1 ratio. Does this stand for every 2.79 turns of the driveshaft the rear axle spins once? Going to something higher up like 3.5's or higher would increase torque pretty dahm good correct? But wouldnt that also mean that the engine would have to run higher RPMs to achieve higher speeds. basically if my car can hit 120 now, will its top speed go down if my engine cant provide the RPMs? Thats something that i wouldnt mind, i want low end power more than top end. What would you guys recommend as well for a currently stock 289 engine w/3spd manual tranny for the time. Also, Since i brought up RPMs I dont have a tach on the car and was wondering how many RPMs these engines put out, and what is there Safty Range in RPMs. When I do a little rice butt kicking i shift out of 2nd around 60mph, havent noticed 1st since it comes up so fast. Am i shifting too late and risking enigne damage? Thanks guys ---Anthony I was gonna start a topic for this but didnt want to put a whole topic for something this simple. ------------------

Well yes and no. If you have a 2.79 rear and your car has the power to pull in top gear than yes your top speed will go down. On the other hand if it doesn't rev up in top gear your top speed might remain the same but your cruising around rpm will be higher.For example the new Corvettes pull top speed in 5th not 6th. If you are going all out in 5th and shift to 6th the cars speed will begin to drop because it can't pull such a tall gear. As far as rpm I was able to turn 6800 rpm with semi polished rods and forged pistons. For regular street use I was able to do this all the time without any problems. For once a week drag racing this was also fine. For road racing you would probably need to beef up the bottom end since the stress would be for longer periods. I'm guessing you have stock heads so you probably don't make power past 5500rpm.

Thanks, Before i go into the driveline of the car is going to be the engine where im gonna look too edelbrock for heads, intake, and cam. Its hard getting money for my car with my crapy job, its time to look for another job.
Although i currently dont have the money to do either, which would you recomend 1st, a tranny swap or a rear end. Im planning on the rear end since i dont have a locking rear end right now  I will also gain some low end torque too, Im also hoping that it will help me get rid of the "Dead power range" that i get going into 3rd gear, anything above 70-80mph pulls hard till the 105mph range where it settles at around 115-120. In daily driving i shift into 3rd at like 40 so if i plan on FAST POWER its back to 2nd till i get to 60mph. ------------------
