Called Thunder Racing today and ask them to recomend a cam for my set up. The guy told me that the 220 on 114 would be the best for me. I was hoping to go with the 224/224 on a 112. I will be going 112 no matter what but I think he might know a little more than I do when it comes to cams but I just wanted to see what you guys thought. Is there that much of a diffrence in the two? I seen (CRAZYCUTTERS) Thread about the 224 in a 4.8 so I thought I for sure could put one in my 5.3 and have good luck with it. But I dont think I'm going to spin my motor to 7300 I will be shifting out at no more than 6400 I dont think any ways. So what do you guys think about it?

 

I just order a lingenfelter gt2-5 222/222 for mine. I think that thunder or any retailer is going to be conservative with thier recommendations because if they go over board it would create unhappy customers. I called them about the 224 and the guy thought I was crazy for wanting to put it in a truck, "all you guys want to put these big *** cams in trucks blah blah blah...." sort of an aasshole

From what Ive learned about cams the larger you go in a smaller engine the less useable powerband you are going to have unless youve got a built bottom end and can turn it over 7k and thats just too expensive on a small motor for the gains
you really need a higher stall to take advantage of a bigger cam though so I would do that first before the cam. then you'll be haulin *** as long as you can get traction

hope this helps

 

I was the first person to put a 220/112 cam into a 5.3 and I can tell you that if you dont pan on reving past 6400 then dont get a 224 for sure. I rev my 220 to 6700 shift points and would go higher but my exaust is a little restrictive and im on stock heads. dont worry about reving that high, with a set of rod bolts you should be safe up to 7000 regularly. Ive hit my 7400rpm limiter 4 or 5 times with no ill effects. Thunder Racing is who i dealt with for my cam swap and was pleased with the customer service. I guess it may help to know most of the guys who work there. They know what they are talking about. My 220 is the perfect cam for me and my setup. Its a big enough cam to grow on, but isnt really radical. check my dyno sheet and 1/4 mile times and see what you think.

hey quick,
i know you probably got a deal on yours but anyways, how much does thunder usually charge for a tune. i'm ordering the tr220/112, 3000k stall, and e-fans to go along with my mods. maybe even some long tubes b/c i think the cam will need them, what do you think.

 

WGFast,

What motor are you using? The 4.8 is at a slight disadvantage if you are not willing to spin it high. The 15'' manifold runners limits us 3.62 strokes to a 6200-6400rpm peak. A 4.8L w/ a 3.28 stroke would need 6800rpms to reach the same piston speed. In other words, a camshaft that creates a 6200rpm peak w/ a 5.3L, will create a 6800rpm peak w/ a 4.8L

But again, what motor are you using?

 

What about a TR224 on a 114 LSA in a 5.3 ???

If you are talking about quick he is running the 5.3

 

Naw, I think he's talking about wanagofast (WGFast)...Zed

 

I'm running the 5.3 and dont plan on any thing over 6400 max. This is my daily driver and dont wanna risk it. thanx.

 

The tune should be around 450-500$ May seem high, but thats dyno time, wideband and free tunes untill your a happy camper. Good luck man.
