[383 hatch]

A beefed up Turbo 350 will handle 400-450 horses without any dramas. Much lighter & smaller than the Turbo 400 but much stronger than the 4L60E!

 

[Heeey!!]

vr304 im in syd. yeh people are telling my to got either turbo 350 or 400 but i wanna minimise any mucking around if possible, i might be alright with the stock box beefed coz a couple of places have told me now that they can handle 500hp if worked properly.
thanks for all the input guys.

 

[Heeey!!]

just spoke to a guy not far from me who does race box's and said he doesn't do 4l60e but he is offering me a th700r4 with stally to suit rated at 500hp handling for $3800.

my question is what is ivolved in adapting the th700 to my 5L and making it work e.g kickdown etc?
cheers
