alright heres my problem right around 60-70mph at WOT the car acts like it has a lack of power but once it gets to 70 it just gets back in it again like nothing was ever wrong. The shop i used to work at the owner said it acts like it just doesnt have enough torque right there. any help?

 

do you have a 5spd or an auto.....either way the upper gears are meant to be gas saving gears so upper rpm acceleration will be slow.....

 

its an auto well im hoping with the head swap onc ei finally get it done and the cam it wont be a problem never did it till i got the comp reprogrammed

 

I have to agree with slego on this one. 60 to 70 is a standard highway speed and V6 Stangs are econo hwy cars. When I put my 4"10's in it changed everything and now my RPM is around 2500 65 mph (if I remember correctly) and if I stomp on the gas at 65, it shoots like a bullet.

 

so will swapping on the split port setup p&p with a cam take care of that?

 

more power will help but better gearing will make the biggest difference....its hard to change gearing in the tranny but some 4.10s out back should liven it up a bit!!

 

definately change to a different rear-end gear and you'll be closer to you "power band" when you're at 70. Going from 4.10's to 3.27's will be a big jump. You'll be at about 2500rpms at 70mph. Compared to being at 2000 where there is almost no power.

 

4.10s huh what all will i need to install them?

 

you should just need the gears, but a shim kit could never hurt either.

 

Yea i'm thinking about going 4.10 or 3.73 in my manual v6
