How Good is Turbo 350?

My 1970 truck had a 350ci w/ th350 , i'm putting a new 454 instead. Do you think a th350 will hold up? Here's what's in my motor
454 from chevy 1 ton
9 to 1 compression
balanced lower end
crane roller rockers
new bigger pushrods and guides
new valves
comp cams with .504in lift .510ex lift
performer 2 intake
750 performer carb
new hei distributor w/50k coil
msd 6al
msd 8.5 mm wires
holley mech fuel pump 110 gph

any guesses what this could be putting out? I've been told about 425hp but i don't really know anything except it's pretty fast in the 1 ton when you ain't shifting that granny 4spd. I have a good th400 is it worth the trouble to make it fit?
