randy 77zt Posted May 2, 2005 Share Posted May 2, 2005 a buddy invited me to watch his new boat engine get dynoed at westech performance group.the place that the car mags dyno thier engines.engine is a big block short deck chevy with 555 cubes.runs on pump 91 octane.runs a short tunnel ram and 2 750 holleys.built by dne motorsports in costa mesa.after some break in running first pull was 790hp at 6100 rpm .after tuning and synthetic oil change made 802 at 6100.hp was over 700 by 5000 rpms.almost 800lb/ft of torque with over 700 by 5000.engine didnt idle bad at 1200 rpm and always started with a tap of the key and no throttle.i always wanted to check out a real dyno room for awhile.this would be fun in a z.loaded motor minus header weighed 675 lbs-it was hanging from a scale going into the boat.might get a ride in the boat next weekend.boat is a 19' jetpump boat.i know some import motors have made this much hp but not this much torque and not at such a low rpm.i would get thrown i jail driving a car with this much motor.probably will never be in a dyno room again unless i hit the lottery and its one of my own motors.but i had to do it once.
