After all this reading and learing the stock arms can release the deadly needle bearings throughout the motor, should I get a set to be safe. My cam is a tr224/.561 on a 114 lsa. Now it still has all stock programming and only hits the stock rev limiter, but tuning will come this winter and will rev more. I also like to dyno the car which is, from what I hear, very hard on a motor. Seems to stay up in the high rpm's for a while.

Well, should I or will the stock last? Lot a money for a mod that you may not need. What should I do?

Thanks guys...

 

If you don't have a very specific reason to buy them, I'd just leave the stock arms on there. Its pretty rare to have a rocker arm fail, and even then, its very very rare that when they do fail they do any damage to the motor. Generally they all just sit down in the oil pan and you can just replace the rocker arm.

 

Read this post and decide for yourself:

I got em just in case. Three benefits I see:

1. Added durability/piece of mind
2. 7-8rwhp on a heads/cam car
3. quiets down the valvetrain

 

verbs hit it on the head, I'd also add that since they're lighter you'll have better valvetrain stability and loner spring life due to less mass the spring has to raise.

 

cheap insurance - i bought a set and they are great so far...the only other alternative from stock is to by the much more pricey Jessel rocker assembly

 

Thanks guys. I ordered them and they are on the way. Looking foward to the install. I just love working on these motors. Its so much easier than the 1st gen small blocks. And the tools the sponsors are comming up with to make it even easier is just priceless. Only problem is parts are a little more than the old sb's.

 

Well, the only thing they can hurt is the wallet

I would get them just for peace of mind and to quiet down the valvetrain.
