nitrous 5.3
#3
10.7 is the fastest nitrous 5.3 I know of. I think the fastest stock head and bottomend 5.3 I know of is 12.0, but it had a cam I believe. Stock 5.3 on spray isn't too common. It happens, but then its a question of what constitutes a stock 5.3? Boltons? Stall? Tuned?

Completely stock long block(as it came from gm) 5.3 on spray whether it be fi or carbed. I put a 5.3 in a 92 Silverado and going to be spraying and just curious what times people were running on the stock longblock.
