I ran my 1999 Silverado ecsb silverado tonight mods are lq4 comp 212/218 tune electric fans stock exhaust other than muffler stock stall and 3.42s with factory 20s 31 inch tall tires. It even has stock air intake tube other than cone air filter. Truck has zero weight reduction so its a pig. I just finished installing the engine 2 months ago. I am not really trying to build a race truck just wanted to have extra power with no loss of drivability. I didnt run the truck stock because it was very slow. Anyway I ran a 9.8 at 75 with a 2.5 60 foot time. I think the truck could have went a tenth or two faster with more runs. The gears in my truck are wayyyyy worst than I imagined I guess Ill do 4.10s when i get a chance. I would have liked a little better time because the truck feels very strong way better than the 5.3. Oh this was all done on a budget of about 1200 for all performance mods.
