5 3 Cam Swap
#1

I have a 5.3 out of an 06 Silverado. While it's out I want to put a cam in it. I don't plan on switching up heads yet. They have 862 on them but I will be going with an ls6 intake. Id like a big mean lope sound but have been told I can't go very big on the lope (ex. Tsp cam that has a .615 lope) just wondering what suggestions anybody has or what anybody with a 5.3 is running. This will be a performance motor but driven quite often.

I'm going to go with a 700r4 & I've done some asking on nastyZ28 & since I'm running stock heads/compression I should go with a mild cam in the 220-230 range with a mild LSA. I know the bigger the cam the bigger the stall so I'm thinking at least a 3000 with a cam in that range. The car is going to have the street strip attitude but it will be a lot more "street" than strip.

Just want to get some good power out of a good cam that sounds nasty although I can't get as nasty as I want since I have power brakes which is the reason I was recommended to stay in the 220-230 range for enough vacuum.

I figured a 3200 stall I was just thinking at least 3000 for the cam I stated above. What are your prices for the cam you just suggested? Or maybe one with a bit more lope at idle?

Especially in a 5.3 with less displacement. The 217/221 camshaft would have a nice idle for sure.
Custom grind Comp camshafts are 400 dollars. We also are a dealer for Bullet and just recently I was asked by Kip Fabre to become a dealer for Cam Motion. Both Bullet and CM camshafts are 450 dollars shipped.
Lots to choose from!

Max lift has no bearing on P to V clearance. When the valve is at max lift the piston is traveling down the bore to bottom dead center. The piston is pretty much as far away from the valve as it will ever be when the valve is at max lift.
During valve overlap when the piston is approaching and or at TDC is the only time to be truly concerned with valve lift. As this is when the piston is closest to the valves as it will ever be.

What's your opinion on this cam
226/229 Duration .575/.578 lift and 112 Lsa
It's on craigslist for only 140$ I'm thinking that'd be good since it'll keep me into vacuum range and it's not a radical cam.

All of the cams I've suggested will lope at idle. Most think that they need a huge camshaft to sound good while idling, but in reality it doesn't take much valve overlap to achieve.
Especially in a 5.3 with less displacement. The 217/221 camshaft would have a nice idle for sure.

LS6 cams work very well in smaller displacement engines. I think you'd enjoy it, but you'd miss out on the muscle car lope. To some that isn't a deal breaker, but to others it is.

Well I've done research and a lot of guys do the ls6 cam and it'll still give me power over the stock cam for half the price of a custom cam + springs. I recently just saw an ls6 cam with springs for only 200$. & since I'm on a tight budget like most it seems like the best route FOR NOW.
