I am looking to boost the horses on my silverado. My motors a 5.3 with 295hp, and I want to get 425 horses out of it. I do not want to add any power adders to the motor, I just want it to be all motor. If anyone could help me out on some outstanding parts and products that would be awesome. Here are a list of somethings that were thought up.
K&N cold air intake
Hedders
Heads
Cam
stall
Thanks.
