I'll be installing a 5.7 LS1 into my RCSB silverado. I will use the truck intake, tb, and exhaust. The truck is not for racing, although I want it to be faster than the stock 4.8.

Right now I own a stock 4.8 cam, and a stock 2002 ls1 camaro cam.

I am not new to custom cams, but that idea will cost me around $800 with matching valve springs.

Are there any off the shelf cams that would work well with my combo?

This is a mild daily driver that needs good gas milage and good idle..

Thanks

 

Tsp 220 or 224. with a budget circle d 3000 torque converter. There is a thread below a guy that installed a 220 in a 6.0 I think and it ran great!
Fyi u still have to buy better springs...

 

I'm thinking a Comp Cams 212/218 ($390) and LS6 springs ($80). Don't want to go too big with a 4.8 if you want to stay with the stock converter.

Thanks for the suggestions. The engine is a 5.7, not a 4.8. And I haven't yet decided if I will be upgrading the converter.

I really want the truck to keep its drive-ability. Good gas mileage and the ability to tow are a must. Will a converter affect either of these?

 

Ok, I saw 4.8 cam and misread that as 4.8 motor. Yeah, with a 5.7 engine, you can go a bit bigger if you want. I revise my recommendation to a TSP 220 with 114 LSA. A cam kit is on sale right now for $610 that includes cam, decent beehive springs, and hardened pushrods.

Agreed^ Just make sure if your gonna upgrade your converter or not down the road that way you can choose a good size cam for that converter. Otherwise stay in the 220-222 range.

 

Hey guys while I can appreciate that these shelf cams work for other combos, I was kinda looking for a cam that has become popular for working in a 5.7 ls1 in a heavy truck. The TSP stuff is designed with camaros or vettes in mind. They didnt grind those cams with a heavy truck in mind. Even Tick Performance's website shows no shelf cams ground specifically for a siverado.

I've played the guessing game before, and my idle sucked, and it had poor vacuum. Then I went custom and I loved it. I think I'm just going to have to bit the bullet and have a cam ground with my entire combo in mind.

Thanks for your suggestion though.

You did bring up a good point. I need to do some converter research. This is my first auto build, so I have alot to learn when it comes to coverters.

Will increasing the converte rpm cause other aspects to suffer? Like gas milage, or ability to tow?

 

Plenty of truck guys have used the 220 cam with good results. The key for a mild idle is a higher LSA like 114. Heck, you can get the Texas Speed 220 in a 115 LSA too. I used a 224 cam with a 114 in my 5.7 GTO. It's a heavy car, like 4000 lbs. Obviously not as heavy as a truck, but still heavy. It idled nice, most people could not even tell I had a cam and I used the stock converter. The 220 duration cam will give you even better low end torque and even a smoother idle. Seriously, you will not be disappointed. Custom grind cams are not magic voodoo.

 

i would go with an ls2 cam and springs for what you want.
