is this true about a 350 sbc vs a sbm

If you are limited to stock heads and can only change to after market pistons , intake, cam and carb I will own a small block chevy with a 360 all day long. If you want to be the faster you better have deep pockets! The mopar block is stronger and will live longer. The chevy guys making big power and living longer doesn't come from chevy. The block and heads say something like DART on them because chevy didn't make them. The weak link is your engine block and none of them can take 500+ continuous horse power. They only live in short burst. I always heard from the old timers chevy blocks were crap. Ford and Mopar were stronger. If the chevy guy likes the ls series.... that's a different animal and it's high dollar. I've seen a lot of round track chevy 350's with big holes in the block when they blow. I've also seen 520 cubic inch mopar eat itself after 10 years bracket racing. Best parts inside, factory block. 900+ horse power, over 1000 ft pounds of torque. The boy cried like a baby!
