I'm still planning on what kinda parts should go into my new engine build. So far my list is like this:

224/230 cam
Ported 5.3 head
Patriot Dual Gold spring
Comp Cam pushrod
Fast 90/90
Cryogenic treated stock crank
Forged piston -3 cc
Forged connecting rod
UD pulley
Pacesetter LT with TSP catted Y-pipe

I haven't decided which rocker arms I should use. I'm debuting between Harland Sharp non-adjustable roller rockers and stock rocker arms with Comp Cams Trunion Upgrade Kit. With my set up, which rocker arms you guys prefer? Power goal is around 420rwhp and the motor will not see boost or NOS.

 

Not a big fan of the HS rockers so I voted stock. Not-stock I prefer the Yella Terra over the Harlands.

 

I agree Yella Terra is the way to go!!!

 

Nothing wrong with stock ones for this app.

trunion kit and run it

Trunion kit gets my vote.

 

Why the trunion upgrade? and what's it cost? My roommate is doing it and I'd like to find out more about it. For the cost of the upgrade should one just get the Yellow Terra's?

 

The yella terra are like $500, the comp cam trunion upgrade is just over $100. If you have money to burn get the yella terras.

I went with the trunion upgrade just to keep the stock rockers from losing their needle bearings. Unless your setup is really wild, the trunion upgrade is good enough. And they're easy enough to install.

 

At what kinda power lever or how aggressive a cam will need a roller rocker arm?

 

I believe it's above .600" lift that you should look into roller rockers.

 

^ Woops.. .639" here and running stockers w stock trunnions. Gonna do the YT's soon tho. I'm gonna have to do it soon though. 59k on the stockers (59k mile car) and almost 10k on the h/c setup (gonna need new springs soon too.) Just gotta watch out for valve guide wear also.

 

how many miles on the rockers?they wear out if you don't change the oil.yella terra $400.comp cam trunnion upgrade $130.

 

I like my Yella Terras. Go big or go home...( i guess that would mean Jesel )

 

trunion kit is what i voted. just got done doing mine... super easy. you just have to be a little mechanically inclined and have some common sense.

EDIT: and PATIENCE

 

WS6store has the Yella Terra Ultralights for $408, cheapest I've seen them anywhere. I just picked up a set a week or so ago.

 

^ Will those fit under the stock VC's??

 

Stockers with trunion kit unless the heads have bronze guides then you pretty much have to use roller (or at least roller tip) rockers to prevent premature guide wear.

 

What about the comp cam ultra gold roller rockers? Have not seen any reviews on this rocker, which looks like a good design.

 

I run the stockers with the Comp trunion upgrade (.621" lift), The body of the OEM LS rockers are a very good design. Replacing the weak point, the trunion, is great insurance. Plus its only $130!!!

I wouldnt buy any heavy aftermarket rocker at this point. They just put added weight where you dont want it, over the tip of the valve. Roller wheel are just added weight, and have no value. People eventuly will learn the sliding pad, like the OEM rockers, is a much better idea!

 

Yeah they fit under the stock valve covers.

 

If someone is too lazy to do the uprade trunion themselves or too impatient to get them done by HS the TxSpd has stockers with bearing upgrade for $400. Im not a fan of HS rockers or their bearings. Ive seen both fail numerous times on different cars. Heavy *** rocker as well.
