So for those of you guys revving high rpm and making big power which roller rockers do you recommend for daily driving & street racing? I am currently running a custom grind camshaft 250+Duration/650+Lift with TSP LS3 Heads equipped with 2.165/1.59 valves, Hollow Stem Titanium Int, Stainless Steel Exh, Milled 68cc, 11:5:1 Comp. I am still running the Stock Rockers since there wasn't a aftermarket rocker on when i bought the heads. I am not exactly sure which way to go here because i just bought a daily driver so the car will not see much street use maybe 3-4 times per week and i want something that will handle the amount of abuse that the LQ9 Iron Block Bottom End was designed for by LME. So anything suggestions would be great to hear from you guys who've had goods & bads about this part. The car dyno'd with a bad lifter 546/513 with a stock unported L76 with a TSP 92mm Ported TB through a M6 with 4:10's on a 295/55/15 MT.

 

Id go with the Harland sharps bud!

I had them on my Ls1 and NEVER had a problem. I hardly hear of them having troubles.

 

what do you have to spend?me i'd use T&D rockers but they aren't cheaply priced like the harland sharps.

Just do the trunion upgrade on the stock rockers. You wont gain any power by going to roller rockers and many have issues with aftermarket rockers.

 

Where did you get hollow stem titanium intake valves?

I was wondering about which rockers to use on my ls3 heads as well, stupid offset rockers.

 

I'm kinda liking Yella Terra's 1:7 ratio rockers...

 

I've been running YT's for about 4 years now. I did have one break but was told that there were a few sets that got through QC. They replaced the whole set immediately.

 

Those are trunion upgrades, and he is asking for "roller rockers"

He has more than .650 lift and its not recommended to run a stock rocker past .630 - .650 due to geometry issues.

 

most of the people are having them on lower cost ones not the better brands.T&D etc......

 

I had a set of T&D rockers on my 408. Geometry was FUCkEd to say the least. Called T&D and was told they were fine on anything but a race motor. WTF do you think we build over here? Fiat's They said the design was the best you could fit under a stock valve cover. They would never refund the full amount of the shitty rockers. Went with a set of custom DRE (Dearborn Racing Engines) rockers for my LS3 heads and although there was ALOT of grinding to do to the heads and moroso valve covers to get them to fit, they had no problems @ 8300 RPM!
