Make sure you keep us updated. I am considering this build as well, cash permiting. There was mention on tech that GMPP may offer a crate based on the lsx block. May be this summer before I decide exactly what I want to do.
this is about Reggie Jackson's LSX powered carbuerated 454
The bottom end of the engine uses a Lunati rotating assembly with forged parts and Mahle pistons that combine with the LSX heads to deliver a pump-gas-friendly 11:1 compression ratio. A custom-grind camshaft was sourced and Comp Cams supplied the remainder of the valvetrain components.
At Warren Johnson's dynamometer facility, the LSX engine produced 641 horsepower and 611 lb.-ft. of torque. More than the peak numbers, however, is the engine's Kansas-flat power band. The engine makes 520 lb.-ft. of torque at only 3,000 rpm, with torque rising steadily throughout the rev range.
