Small block bottom build horsepower limit

state is Nevada. I would guess he races at Winnemuca. Jack said he races at 6000 feet altitude.
not sure how much he races either, but this is his second year on the motor, so it’s certainly not just a show poodle.
6.40’s at 6000 feet altitude is not slouchy at all. He was recently in a final against a B1 headed dragster, so I would guess he races box

My buddy has had the same engine in his front engine dragster for 30 years. If you would talk to him at the bar you would swear he raced last night. He used to brag about how long his engine is lasting, probably still does to a different crowd.
