5.3 cam choice I just got a 5.3 LM7 out of an 04 Silverado and Im looking for a cam. Im building a carbed motor that is going into a S10. The truck is a street truck but I like a choppy idle but something that is still driveable. These are the cams I found so far so let me know what you think will be the best and if I will have to do any mods for it (springs ect.)
- 212 intake 218 exhaust @ .50, 551 551 Lift on 114 LSA
- 03 LS6 Vet Cam
- Intake- 196 degrees of duration at .050" with .467" of Max Valve Lift.
Exhaust- 201 degrees of duration at .050" with .479" of Max Valve Lift
Any other suggestions on a cam choice?

any cam you choose is going to need new springs and pushrods.
a tr220 seems to be a popular cam on the truck boards. But depending on weight you could go a little bigger.
is the vehicle an auto? torque converter is another thing to consider. i wouldnt run any cam with a stock converter.

Yeah the truck has a 700r4 with a 2800 stall converter. Its right around 3000 lbs.
Now when you say I need to replace the push rods, do you mean with a more heavy duty rod or a different length depending on lift and rocker ratio? I'm staying with the stock 1.7 rockers if that helps.
