Looking to do an 06 gto ls2 w4l65 into my 64 impala convertible.. Looking for any input on what to use--car will be a street cruiser-has 383/700r4 now with 10 bolt posi with 3:55 rear end

harness will be psi or modern vintage

what i have questions about are

What radiator for ls swap?
Should i put a new cam in ls2? Can i keep stock converter

Surprised your ten bolt rear is still in one piece (though tires are the weakest link) with the 383.

As to radiator it has to have provisions for the steam lines from the LS heads. There are aluminum radiators that are designed to work with this motor in your '64. The LS-2 like all computer controlled motors will have to be retuned to accept a non-stock cam, and you are limited to a computer motor cam grind (which has a wide, wide LSA and narrow duration compared to a SBC cam with a carb application).

There have been a number of members who have spoken out against the Borgeson conversion and list the problems with the swap as well as what you have to do to fix the problem introduced by installing the newer Saginaw gear box into the older car frame.

I might remind you that the Corvette retained the power assisted steering used in your car through 1982. Parts are readily available to rebuild your car's front steering parts with Corvette parts if yours are leaking.

@ BIG FAVE

I appreciate the response..My power steering is not leaking-I'm just tired of the side to side-bump steer and want to address it.I'm changing my shocks to ridetech shocks so want to do those 2 changes while I gather up what I need for the LS swap. In talking to a guy that has a 62 he swapped using a 96 IMPALA SS gear box (was told its an 800Z) with an 82 Corvette pitman arm--not sure how he found this but hes really happy with that set up.

Bump steer is caused by improper steering geometry. This is aggravated when you lower (or raise) a car or truck. As I said the Corvette which has the same front half frame rails and the same power steering parts (but with fully formed a arms) as your car doesn't suffer from bump steer.

You might consider looking at a C2 to a C3 wrecked in a bone yard as a source of a front end trans plant of the fire wall forward frame and suspension parts. The Corvette had bigger tires and better brakes which would magnify any bump steer issues.
