I'm sure others here who are better informed will chip in but I would have thought that a 600cfm carb would be on the small side for a 383 stroker. I have a 350 putting out 430hp and have an 800cfm carb on it.

Carb is going to be too small. You will most likely need a 750. As far a trans if the th350 is in good shape it should hold up. A th350 will hold up to your engine it will just depend how much time yours has left.

Normally 600 VS are used for mild 350s.
Which Holley 600 & what's the intake? AFR did a 383 w/ a Holley 600 DP w/ about 420 HP.

So far it sounds like a 650 DP would be better for your setup or 750VS.

I ran a big block 427 pushing 500 horses with a Turbo 350 and had no problems. Just make sure it's in good shape. I have a 383 stroker in my 61 with a Speed Demon 650 double pump. It feels a little under carbeurated. I would go with a 750. You will enjoy that stroker. They are stump pullers.
