TR224 cam?

[ekordas]

anybody got any results from dyno/personal opinion on the TR224 cam? buddy has a 2000 TA with the TR224 in it. hes goin bigger so im taking his cam off his hands. any pro/cons?

con= that cam is for a car not a truck. (big cams are for light race vehicles, that need lots of hp)
con= you will need a bigger stall converter & tune for the cam
con=you will loose bottom end, low to mid range tq when going with a larger cam. (it will shift your powerband)

That said, I would look for something along the lines under a 217 cam for best power in a heavy ass truck, especially a XL/suburban. Think about it, a 198 duration cam would make more usable torque than a 217. What are you using the truck for? Hope you did not pull the trigger on that cam, because of the hesay on numerous forums.

Its a reason the stock cam is like a 196 duration or something. But a good upgrade would be around the 210-217 duration. 224 is on the limit of passable in a heavy truck.

people I've talked to added like a 3200 stall, re-tune and they ran great in a 5.3....

Ls engines run well with cams, but seriously a 3200 stall in a big ass truck is ridiculous. Its like spinning half your rpms just to get moving. The next new thing is going to be a 230 cam with a 4000 rpm stall converter.. Again, this is really not what I would consider streetable, daily driver for such a heavy vehicle like ours. I would want a cam that kicks real hard at 2000 rpm with a 2500 stall converter, with a smaller duration like 216 or something. But thats just me, and my opinion of how a truck should drive. I would want the flattest curve possible. A really broad spectrum, not a sharp pointed peak.

with my 6.0 im going to be putting a 228 in my ** in the spring..zippy on pt.net ran one in his tahoe with around a 3k stall and it hauled ass...a 224 is a great cam as well as long as you have the converter to back it up..for a 5.3 most people are running a 220 or so...

my 3k stall, in my tahoe which with my wheels was 6100 lbs, does just fine..sure you gotta give it a little more gas in certain situations, but after a week you are used to it and it drives just fine..the pros def outweight the cons if your going for performance

actually, all LS motors like cams, they have too
I ran 4.11 gears and a 3500 stall daily with 11:1.
These stcok would like a 2800--3000 cam as they sit now. Stock, they pull in the higher range. Sure, a 212/218 is a great cam, but if someone had a 224 and 3200 with 4.10's or 4.56's in a SUV, it'd run good too...

just because someone has a 3200 stall, doesnt mean it has to go to 3200 to get moving.

word..i barely get above 2k in town..i mean most of the time i get on it cuz i like to drive like a ******* lol, but if im just crusing its barely noticable

Zippy wasn't running a 228. He did 5.3 heads 863 castings I believe on a LQ4 with a TR224. I think a 224 would be too big in a Suburban. Especially in a 5.3. To say it is a race car cam and doesn't work well in trucks is laughable. Look on pt.net that cam is almost as popular there as round rubber tires. The statement of a 3200 stall being to big and giving the impression that the vehicle doesn't move until the stall speed is reached is again ludicrous. There are several factors to how a converter behaves beyond stall alone. Do some research into STR rating which dictates how tight or loose a TC feels. The higher the str the looser and more rpm it takes to get moving and how lazy it feels. The lower the tighter and snappier it feels. As long as my wife's Yukon doesn't sell I'm swapping in a lq9 and 212/218 cam. Don't focus solely on peak power and sound at idle. Look at torque curve and width of power band like stated.
