Need some help
So I bought a 84 Firebird about 2 months ago, it has the 305 and the gentlemen said a 200 -4r tranny. My expertise is hardly in the wrench turning aspect of things, I am the appearance guy. I have completely restored the interior with everything new, have the car prepped for paint and plan on painting it this week. My plans are to move on to the Engine/Powertrain in December. I have found several 383 strokers that are so called "turn key" that I am considering, I have read that the 200-4r will handle the power and torque with ease if I upgrade it properly. Is this true and what would an estimated cost of upgrade be? Do I need to upgrade gears/rear end? Basically this is all foreign to me so any advise is appreciated

Re: Need some help
It most likely doesn't have a 200-4R. These cars in the configuration you mention never came with that.
More likely it's a 700.
Step the 1st is to correctly identify what you've got.

You are correct, I just looked and it is indeed the 700. So then that should be able to handle a 383 with no problems correct?

Re: Need some help
yep,should be good-if it goes wrong,just pull it out for repair/ replace-pretty easy job on a 3G.700 had some upgrades in 1984,original tranny in a 1984 model could be 27 or 30 spline input shaft.

Re: Need some help
I'm not going to go out on a limb and say that YOUR 700 will handle anything in particular "with no problems". But yes in general, a 700 CAN BE adequate for a 383.
