I Currently Have A 2000 5.3 With K&n Spacer Exhaust And Hpp3 And E Fans I Am Running 14.8 In The 1/4. I Finally Recieved My Check And Am Planning On Adding Hot Cam Kit, 4.10's, Headers W/cutouts, Torque Converter, Shift& Servo Kit, And A Pcmforless Tune. What Do Yall Think I Should Expect From The Old 5.3? Hp And 1/4 Mile

 

is your truck a reg cab? I would say low 13's high 12's in my opinion.

 

Its A Rcsb

 

How Much Difference Would It Make Without The Cam

 

Honestly i have heard gains upwards of 60RWHP with a cam on the GEN III motors, so you do the math, also you will see better gains with the mods you have, especially with the stall.

 

I know the 212/218 High lift comp cam makes about 40-48rwhp because I talk to some one and they said that. For drivability it really makes power. I know it is usually consistent with all that have that cam love it for what it is.
