depends on your budget and your ability. Best swap IMO is a SBC 350 but it's $$$. Then there is your 1UZ but that's $$$$$ and I would think will take more fabbing then a SBC swap.

plenty of 350 swaps here to read up on: https://www.yotatech.com/forums/f163/
I wouldn't go LS1 though. Maybe a TBI. Lost most of my SBC knowledge as it's been a long time, but I believe the blocks are totally different then the CARB/TBI ones.

The 4.0 L (3,968 cc/242.1 cu in) all-alloy 1UZ-FE debuted in 1989 in the first generation Lexus LS 400/Toyota Celsior and the engine was progressively released across a number of other models in the Toyota/Lexus range. The engine is oversquare by design, with a bore size of 87.5 mm (3.44 in) and stroke of 82.5 mm (3.25 in). It has proved to be a strong, reliable and smooth powerplant with features such as 6-bolt main bearings and belt-driven quad-camshafts. The water pump is also driven by the cam belt. The connecting rods and crankshaft are constructed of steel. The pistons are hypereutectic.
Its resemblance to a race engine platform (6 bolt cross mains and over square configuration) was confirmed in 2007 by David Currier (in an interview with v-eight.com), vice president of TRD USA, stating that the 1UZ platform was based on CART/IRL engine design. It was planned to be used on GT500 vehicles, however its subsequent use in the Daytona Prototype use was not planned.
In its standard, original trim with 10:1 compression, power output is 191 kW (256 hp), torque of 353 N·m (260 ft·lbf).
1UZ-FE
The engine was slightly revised in 1995 with lighter connecting rods and pistons and an increased compression ratio to 10.4:1 resulting in peak power of 195 kW (261 hp) and torque of 363 N·m (268 lb·ft).
In 1997, Toyota's VVT-i variable valve timing technology was introduced along with a further compression ratio increase to 10.5:1, bumping power and torque to 216 kW (290 hp) and 407 N·m (300 ft·lbf). In the GS400 application, output was rated at 300 hp and 310 ft-lb of torque.
