Question 402: What Rockers?



I would appriciate any help on selecting quality shaft mounted rocker arms for the 402...not budget but not 1300+ Jesels either!

We want to spin it up to 7,000 safely and reliably. Here is the beast:

TTP LS2 402 stroker, all forged, Callies crank, V.3 Equalizer cam around 234/238 on 112LSA .600 lift, PRC stage 3 6.0 heads with PRC double springs good to .650 lift, 11.2-1 comp., want to shift around 7,000, Kooks 1 3/4 LTs &Y, QTP cutout, 42# injectors, Racetronix fuel, 4:10 Moser, etc. etc...

Daily Driver Camaro SS VERT (98% street N/A / 2% track N2O):
Thanks in advance!

I think the new Crane shaft mount rocker arms are the best available for the LSX engine. http://www.vincihighperformance.com/...0.HTMLPAGE.htm

Check these out Curtisbilt rockers are very stout peice and easily adjustable. They have been around for a couple years and working great on many cars. Dyno testing has shown great results. Steel rocker bodies with full roller tips free up some power without flex. A true adjustable rocker that fits under the factory covers. No old school guild plates to add.

We have them on special. Retail $795 Sale $675

Hey guys all great information. Yeah

Speedracer5532, I know they to sound awesome, but can't afford them (sux)

Yeah Damian, will do!

Hey Nate, those make sense, seem to have reduced inertial mass out on the tips. Will they rev?

BTW< just emailed you on the fuel stuff.

Nate, you were moving a lot of those Harland Sharp rockers when they came out. What is the report on them? They seemed to be a good value for the money.

They are a great value and an exceptional product. I still sell alot. I use the Harland Sharps on all my personal cars even some custom shaft rockers for our ET 265 heads. Just some different offerings.

It is more/less an upgrade to the fulcrum area... (I assume) hardened fulcrum shaft, upgraded needle bearings, and c-clips. Note that the GM rocker was noted for coming apart... as in spotted complaints of needle bearings showing up during oil changes. The GM rocker does not like sustained (drag racing) 7k+ RPM's... OBVIOUSLY depending on other valvetrain mods including rather large lift, durations on short LSA's, etc. You can call Chad at Xtreme and he can explain the differences... hell, maybe I can get an update to their website with pics soon enough

Thanks, Bill. I did some searching and see that Harland Sharp is selling an upgraded stock rocker with an upgraded trunion.

Default T & N shaft mounted rockers

Thanks again guys, I ended up spending a ton of money on bullet proof T&D rockers, so no worries.

I went with the new RHS Elite 225 heads and they are the absolute sh**!

Intake side, they flow 276 CFM @ .400, 313CFM @.500 (my numbers) and 332CFM by .600 lift...plus an amazing 262CFM ex. @.600 too.

Best, Ram
