My neighbor broke every type of record out there with a street legal 95 RAM 2wd. He was the first to break into the 9's at near 140mph. Stock long lock. The Cummins 5.9 has broken many drag race records.
Agreed you can make them very fast, but a 9sec pro street drag truck is about as far a departure from the intent of the already off topic discussion as you can get.
I know the ISB will hold up to huge power on a stock bottom end, but your neighbor could not have had a totally stock long block.
At the very very least, valve springs were upgraded. And you can't stuff that much air/fuel through with a stock cam either.
Stock short block I might believe, but even that's real suspect. Compression ratio would need to be lower to, to fit the air fuel charge at that kind of power.
