Here is a few photos of a friends 1960 Impala with an LS1 and 4L60-E. He made his own engine mounts. The Impala was done about 2003.. You can find a pullout with L92 engine from a truck, but you have to switch the intake. Anyway, they are from 403 hp.
I just saw a pullout listed in the forums here, from 2012 Escalade.
I used an L92 Engine block with a Harrop TVS 2300. It is hooked to a 4L80-E.
Here is from the wiki...
L92
The 2007
Cadillac Escalade has a 6.2 L
Vortec 6200 (RPO
L92) (≈376 cu in) engine. It is an all-aluminum design which, while still a
pushrod engine, boasts
variable valve timing, a first in a mass-produced non-
overhead cam V8 engine. The system adjusts both intake and exhaust timing between two settings. This engine produces 403 hp (301 kW) and 415 lb·ft (563 N·m) in the
GMC Yukon Denali/XL Denali, Sierra SLT (2009+), GMC Sierra Denali, and in the Cadillac Escalade. and makes an additional 2 lb·ft (2.7 N·m) torque in the Silverado and Sierra pickups, and 393 hp (293 kW) and 415 lb·ft (563 N·m) in the Hummer . It was also available in the Chevrolet Tahoe LTZ, with power ratings of 395 hp (295 kW) and 417 lb·ft (565 N·m) .
