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.
"I thought it was going to blow up!"
