99-LS1-SS

I bought the TSP Custom 224R Cam: 224/224, .581"/.581", 114 LSA with double springs, tit. retainers, hardened push rods, ported ls6 oil pump, and a double roller timing set. The guy that is going to do the install warned me that the rocker arms in these cars are prone to break. If so how long do I have before I have to replace them? I spent my wad on the items mentioned above. It will be a while before I would be able to afford a set of rockers. Also, will the ls6 oil pump cause any problems with my seals?

I have a 99 Camaro SS A4 with Hooker shorties,GMS MAS, SLP lid, Yank converter, shift kit, 2.5 y-pipe with cats, Borla exhaust, and HPP3.(soon to be dyno tuned)

When I did my cam swap, noone told me anything about my rockers. Basically all you have to warry about is your springs and pushrods.

In the 400+ LS1 cams we have installed (most have been 224/.581 cams)with stock rockers, maybe 10 of them have broke a rocker arm. There is no doubt aftermarket rockers are better, and a nice upgrade, but they arent necessary.

When you change your motor oil, keep an eye out for needle bearings. You might want to pour it through a screeen to catch them. The stock rockers are known for slinging them into the oil pan. Then you can just replace the rockers when that starts to happen.

I'd bet better than 90% of the cammed LS1s on this board are running the stock rockers (including myself.)

Like Cal said, just keep an eye out for needle bearings in the pan.

If the car was a 98 with that cam I'd worry about the rockers. I think the rockers will be ok, might want to change them when you do springs to something better for the rockers. This is the route I'm taking with my 99 T/A and a very simlar 224 XE-R cam. We have new rocker choices coming out almost weekly. I rushed and picked up a set of Jesels two months ago and it would have been better to wait with all the new choices coming out.

How is '98 any different with this respect ? Other than causing extra headaches to get valve covers to clear aftermarket rockers ?

Thanks Charles. Maybe I will have something for you with a cam. I plan on getting it dyno tuned around the end of Feb. I have to space these large chuncks of cash out. I can't wait.

Its just more bashing of 98's i guess. All i know isI have no piston slap, Pull 45lbs of oil pressure at idle and have beat many c5's and newer ls1's. The myth a 98 is not as fast is not true. All you have to do is run one and find out. There are some differences BUT the fastest stock times i have seen from Professional drivers have been from 98's. Remenber the stock 98z that evan smith rode to a 12.8 in?????
