Built motor options
Wanting to build a motor for boost and pull my sbe 427 out of the car. Looking into built 427 but pricing it a little higher than I’d like to spend for a car that isn’t a dedicated track car. What options are out there I’d like to make 1200 wheel

The block wont' hold that much you have to start with a new block, the best option if you want to keep the block is to resleeve it with a set of darton dry sleeves, I'm at about 1000rwhp with the LS7 block and resleeved.

I agree. I did 1100 rwhp on a sleeved ls2 block and it eventually failed. No reason to put all that stress on a stock block with sleeves. Go with the LSX, that is what it was made for. It will save you the headache later on.

Expect a solid $50-60k to do it correctly.
For reference, I spent ~$33k just on the motor for my setup. That isn't even touching drivetrain, cooling ,fuel system, blower setup, etc.

A real reliable good 1200rwhp and "cheap" should not even be in the same room, let alone sentence.

Without getting into the nitty gritty that adds up
LSR Block
Callies Ultra Billet CCW 4" Crank
Callies Ultra Billet Rods
CP Custom pistons, ~10:0, ceramic coated, antidet CNC tops, special ring pack, etc etc 4.125" bore
Brodix BS BP BR7 Heads with all the junk (crower shaft, Ti valves, etc etc)
Then all the little stuff that adds up like 6 bolt ARP CA625 studs that were something like $900 just for the stupid head studs
Really the details are were it matters. Stuff like the special head gasket, parallel cooling, timing chain, timing set, oil pump, lifters, etc etc etc etc that all add up.

Jesus. You can buy a 2000 horse power ready engine for about low 20g. Of course it'll be basic nothing super fancy but get the job done. I'm running around making a 1000ish whp on a stock ls 7 block with good internals. Might consider swapping all the parts over to an LSX block this Winter.. Not sure what to do about heads yet
Plus there is a huge difference between 1000-1300hp motor built for a few dyno pulls, or a season, and one built to last 5 years of beating.
Can you do a junk yard build? Cheap build? Sure you can. But saying you want 1200hp and budget, when even if you took the whole motor out of the equation, the drivetrain, fuel system, blower setup, chassis, etc will be $30k+ to be even 1/2 way reliable and usable with a 1000+, and try to nickle and dime the motor is short sighted and why many people sell their projects or don't really how bad it is, until they spend that $20k on a motor, then realize that is just the beginning and have a LONG LONG way to go for a complete usable car.
