I'm needing some to replace my stock rockers with the new cam and im not up to date with the ls1's latley. What i want is a rocker arm kit that will work with my cam only setup that i won't have to worry about and will be a direct replacement without having to machine them. Right now i'm leaning towards the comp. magnum rockers 1.7 or is there anything as good or better for a decent price? The comp. rockers are a little pricey but they are reliable.

Whats wrong with the stockers? I havent seen where any others are lighter, or beneficial yet. Everyone jumped on the YT bandwagon and then what happened, heavier and more money spent for a part that only offers "insurance" against stock parts breaking. If chevy uses the stockers for circuit racing then I feel comfy with them holding up for daily driven 10sec pleasure car.

My opinion is that there is no better rocker arm choice than the Crane "Quick-Lift" roller rockers. They can be bought bare or in a complete kit that includes beefier studs, adjusters, guide plates, and special length, heavy-duty pushrods. They are available in 1.70 (actually 1.72) and 1.80 (1.82) ratios.

The 1.70 versions have a ratio of 1.78 when the valve leaves its seat, drops to 1.72 at ~.300" of valve lift and maintains this till the valve again reaches ~.300" as it closes, then goes back to a ratio of 1.78 till the valve is again seated.

I swapped out a set of SLP 1.85 rockers for a set of the Crane 1.80 roller rockers and, in spite of the fact that I lost ~.010" of valve lift because of the slightly lower ratio, I gained 10 rwhp and 8 rwtq with the Cranes vs. the SLP's.

Jesel rockers are not what im looking for. It's to much trouble going with spacers and having to spend more money on different pushrods when others will work without all that crap.

Harland Sharp are nice and there is a group purchase going on right now at

Nasty performance..>>>>> sponsor

Stock rockers are sure nice for most applications...

Some of the aftermarket pieces are too heavy at the valve...

Use J2K Jesels if you are going insane but the stockers sure perform well...

The stockers with the Harland Sharp bearing mod ($250) are good for 99% of applications, then look at the Cranes and the Jesels according to your budget.

where can you get them bare? I have only seen them as a kit for like 699. which is insane. I would get them bare if I could find them. What more would be needed to make them work? Pushrods,etc.

You need the kit. Due to how they designed them; the pushrods work with the rockers, and you need their pedestal.

http://www.vincihighperformance.com/superwebdeals.HTML normally $669.00 but right now there's a GP going on for $635.00 here: https://ls1tech.com/forums/sponsor-sales-specials/323171-gp-cams-rocker-pkg-valve-spring-pkg-vhp.html

you have to use shorter pushrods with these rockers. so, either way, you'll end up buying all the parts in the kit. chrome moly pushrods, screw in studs, polylocks, and guideplates.

Stockers are fine in most motors the sponsors build, so there ok in mine.

XTrooper

I honestly don't know which sponsors you fellas are referring to, but the last dozen or so motors I've seen being built have all had one brand or another roller rockers in them. If you're going to be building a high-revving motor, I'd be worried about finding needle bearings where they don't belong using the stock rockers. For that reason alone, I think swapping out the stockers is a good idea, but that's just me.

These are the 1.7 ratio OEM LS7 rockers. Notice offset, these will not work with standerd LSx heads, but they look very much the same as the OEM LSx rockers.

XTrooper

Let's hope they hold together better than their predecessors.

Why no roller tip? LS7 cam has .591 overall lift with 1.7 rocker ratio.

Patrick G

The way GM sets up the geometry from the factory, a roller tip is not necessary. Also, the ratio of the LS7 rockers is 1.8. The LS7 exhaust rockers might be a nice upgrade to add to intake and exhaust of stock LS1s for a nice boost. Basically, they'd be very similar to the SLP 1.85 ratio rockers.

A cam with a lift of .591 @ valve does sound radical, especially with 1.7 rocker ratio and 210 degrees duration @ .050 lift. But 1.7 (type error maybe?) is what I read from a good source.

I spent the last month looking into this and, I just bought the Crane VHT or "quick lift" 1.8 rockers from Joe Vinci. As mrr23 said, Vinci has a price break on the rocker kits either 1.7 or 1.8 and he is also giving some price breaks on cams and springs, etc.. The concept of the VHT Crane rockers makes sense and I wanted to try to add a few easy HP w/o doing a cam right now. I can't wait for them to get here so I can put them in. Call Joe Vinci and talk to him.
