I've got a bad itch to do something else to my truck. I will be transplanting an iron block ls1 in couple of months but can't wait. Tigerfan has a 224/224 cam that came out of his ls1 that has no mileage & is just sitting there on the ground. I am considering throughing it in this weekend just to see how the 4.8 responds to the cam.

I am not that concerned about low end loss being that I have another convertor (3500 stall) sitting on shelf. I can pretty much figure the tune out as well. I am just curious how the truck would respond with this large of a cam. anyone have any dyno #'s?

who has the largest cam in a 4.8?

 

I know 01 Thunder is running that cam with the 112LSA. He's pushing close to 300rwhp, which I think is awesome! Deckhand and I are running the 219/228-112 cam, aka the infamous hotcam. Personally I wouldn't go any bigger, because of mine being an EC and all, and I don't race it like most of you do. The exhaust duration is pretty long for a 4.8.

I've thought about trying the 224, so I say go for it. You can always take it out if you don't like it.

 

that doesnt seem like alot I made 290 @ the rear wheels with my 212/218 I was hoping for more, what mods does he have?

 

He Has Pretty Much Every Bolt On Their Is.

 

224/224 114lsa. been there. done that.

 

how does it drive? where does it come in at?

 

I think you'll like it. Thunder's was on a 'decent' tune at best. I know he had some other issues there too, but I think overall he was very pleased with the cam.

I say go for it ... it's not like you would be out 400 bucks, and the swap isn't that bad.

 

It is going in as we speek, flyer, we will all be at gilliam tomorrow, can you come?

I figured it would make alot more hp though, we will see here in a couple of hours though

 

 

let me know how it turns out.
I havnt got to compare with another 4.8L on how much it can make.
I think I got 28HP, out of it. but like flyer said I have had some issues I am still trying to work out.. it is coming along tho.

oh and I am also missing a few bolt ons
been kinda alone on this one..
but it will run and run good
