400/450 stroker....Cheap parts, lotta work.

Days ago while I was changing jets on the 450 for another run a friend showed up who had never witnessed a dyno run. Had him stand just behind my left shoulder while we made the pull.

Afterwards I looked back to get his impression.

Not there...........he was twenty feet away across the shop hunched down some with big wide eyes.

LOL...yup. They would like they are ready to grenade and frag anyone within 50 feet of it. The boss had some old Ford on the chassis dyno one day and they made a couple of easy, quick pulls on it. This thing was put together for some class at Bonneville and it was a flat head 4 with some seriously expensive parts on it.

The owner did some physical checks of stuff and he jumps back it the car and they let it rip. Right at the end of the pull two rods let loose and it was spectacular. There was pieces flying all around, water and oil gushing out and a ton of noise. Maybe 1 second later the engine was off and it was almost was quiet. All you could hear was the dyno slowing and some parts still banging around and hitting the floor.

I felt bad for the guy, and of course he blamed the dyno for breaking his engine. Wish that one was on video. He didn’t get charged for the dyno time.

It was one of those sad things that was still incredible to see.
