74 Truck On Dyno

[sc15pro]

Well with 500 miles on a fresh 355 8:1 compression we made a pull (short) due to a bad water pump bearing.At 4000 rpm no boost from the blower it made 275hp and 325 tq on the wheels.Ready for spring to run it again and get it tuned as it is way rich and make a 6000-6200 rpm pull as the cam is good for 6500 rpm before falling off.This is built strong the bottom end consist of a new GM steel crank lightened and nitrated and corillo blower rods $1300.00. But here are some others that ran that day and look close there are some big numbers.

That little truck is a hand full when the boost hits,just ask the guy in a 68-69 camaro haha he had his tail between his legs after messing with a truck.
