Will a cam help me get more out my truck? Bc the cam came out my slightly modded 4.8 and I put it in my 5.3!! Yall think my cam is to small? & what cam should I go with! Please help need info!

 

yes.......

 

I know the 220r cam is a great combo for a stock 5.3 & should I go with that cam or some diffrent cam?

 

With all that work done to your truck and a 3500 rpm converter you could go quite a bit more than a 220/220 if you wanted. What do you want to shift at? I would probably get something in the mid 220's range, and you could very easily do it without any low end loss..

Maybe try to get someone to custom spec you a cam?

Id get something like a 226/226 or 228/228 or maybe a split pattern with a mid 220's intake duration and a high 220's exhaust duration.

If you want to use the same springs, you'll have to keep the springs .600 max lift in mind.

 

I just got too excited to even post a helpful comment because of all your !!!!!!!

If you're set on keeping your valve springs you can go with the tr224 its a good sized cam and not too much lift for your springs.

 

What type of 224s r there
