Default GTA42 on a 383 Lt1?

Heres the story,

I have a newly reman'd GTA42 (GT4202 T6) Laying around the garage. I am currently building a 383 LT1. I was hoping to see if people thought this unit would be a good fit, or if i should go look for a different one. Current goals are to run about 17-20psi boost, maybe a bit more, not sure. Just wasnt sure if I would be running into choke problems or if it was a good match. Also, does anyone know what the power limit on one of these is? Thanks for any input.

The GT4202 T6 is a pretty good match for a 383, but not a 4th gen f-body.

I say it's not a good fit for 4th gens because of it's physical size. BTW, a T6 GT4202 will make enough power for you to run in the 8's.
