What do you exactly have planned for the 5.3? Stock 5.3's are known to take abuse well into the 600rwhp range. Boosted or on the juice. Also, if you had a 5.3 in a s-10 and it only ran a 14.6... something was terribly wrong.Cory, a bone stock 5.3 with just a good tune would make that S-10 run like a raped ape. My 5.3 can scoot my big ass Burban and I know my truck weighs more than twice as much as your does.
When I do a swap I want to build the bottom end so it can handle all the stuff I do to the top end down the road. I had a stock 5.3 in a 98s-10 in 06. It ran 14.6 in the 1/4. It will haul some ass but eventually I'd want more.
