I have a 305 mild moded motor, I have heard that getting a shift kit would help the car's performance. I have a 700 R4 automatic transmission. Is getting a shift kit worth it?

The mods I have are Edelbrock carburetor, a torque 2 intake manifold and a performance distributor.

 

best thing you can do for performance is replace the 305 with a real motor......j/k. yea a shift kit wont make your motor any more powerful, but it will make perform a little better. dont go too crazy with the shift kit if its gonna be a street car. a little firmer shift kit will be fine.

 

The shift kit is nice to have and when I bought my car the previous owner said it had a shift kit and Corvette servo and I beleave that to be true because of the nice firm shifts and one two bark,two three cherp I can get with my 305,but what rear end gear ratio do you have now,and do you have a posi. The largest difference I noticed was when I went from a 2.73 and open differential to a 3.42 and a Eaton Posi. Thats were I would start.Gears and posi. is the way to go IMO.

 

Does any1 whose bought the kit know what it cost them to get a shop to install it?

 

haha ok man thanks ima look into it

 

ima find out wat ratio i got and start looking around and find a good shop to install it

 

About 2 hours labor.
