LS motors are impressive. You can buy a 750hp LS based (LSX454X) crate motor from GM PERFORMANCE PARTS. A 454 cid small block? Ok...it's a small block, GM says so. Not very streetable, not intended to be (13.1:1cr, solid roller cam and a carb, not injected) and not on pump gas. Makes all the hp and torque numbers at "peak RPM" what ever "peak" is. LS motors are impressive, however, with 502 cid big block you can have 502hp @5200 RPM and 567lb.-ft. torque at 4200 RPM, 500+ lb.-ft of torque at 2500 RPM and drive it anywhere/everywhere for a long time with low maintenance on pump gas. You can't do that with a NA "small block". Now... be nice to me with your replies (I'm putting up my umbrella preparing for the sh*t storm I know is coming). Once you go big block you'll never go back.
