I was set on a solid roller setup, but I think I'm leaning towards hydraulic now. If I do end up going with a solid roller, then I'll use Morel lifters and T&D rocker arms. What do you suggest I use for lifters and rocker arms on a hydraulic setup? This will be a naturally aspirated setup. Thanks.

If I do decided to stick with a solid roller, what do you think of the Morel lifters and T&D rocker arms I mentioned?

I'd use Morel lifters on either cam. The T&D's should be good solid arms, but for a N/A hydro app. I'd use Harlan Sharp rebuilt stockers.

Morel makes lifters for both hydraulic and solid roller applications. There's about a $20 difference between the 2.

Harlan Sharp rebuilt LS1 stockers? Never heard of them. What exactly do they do to improve them?

Morels with a Rev kit on top of them...

HS rebuilds the trunion on the stockers with a new cage and needle bearings. It is also C Clipped in so that you can not spill bearings. For HR they are the best bet out.

I just used Melling stock OEM replacement lifters and stock rockers on my heads/cam setup putting down 471rwhp to the ground with the stock-internal 346.

I used my stock rocker arms on my old setup spinning 7200 rpms. That was a cam only setup using the T-ReX camshaft and went 10.30s naturally aspirated. Not sure how much further I could push them, but I wouldn't want to find out. I acutally sold them and wish I wouldn't have because I could of have them rebuilt by Harlan Sharp which is a great option as the tip weight remains the same and its reasonable in cost. (I know that thanks to a friendly/helpful member )

I haven't made up my mind just yet, but I'm really considering a set of L92 heads. If I choose them, the exhuast rockers are the same as the LS1, so I can go aftermarket there, but the intake rockers are L92 specific because they are offset. This will be a problem because I can't have half stock rockers and half aftermarket rockers. Anyone have any suggestions?

Anyone have suggestions they would like to add?

I've got 2 people saying Harlan Sharp rebuilt stockers and Morel lifters.

I guess if I decide to do the HS rebuilt stockers, I'll have to purchase a set of stockers because I sold mine not too long ago.

Im using stock rockers and Comp-R lifters with Comp 921s on my H/C setup [507.9RWHP]

The aftermarket rockers are too heavy for the stock diamiter valve springs.

Does anyone know if the Harlan Sharp mod will be possible on the L92 intake rocker arms?

What's the next best thing to the Harlan Sharp rebuilt stockers regardless of cost?

How do the new GM race lifters compare to the Morel lifters? They rate them for 8500 rpms. They're only $220 compared to Morels at $495.

TSP has an LS7 replacement lifter on their site for only $115, may be worth looking into.

The HS mod should be no problem on the L92 rockers. (intake and exaust) The actual bearing portion is the same between all LS type rockers, so I see no reason why they couldn't do them. They've done LS1 and LS7 that I know of. That coupled with the new GM lifters could be a good option. I had forgotten about those lifters.

I had the hydraulic Morels and J2K Jesel's on my car. Worked fine. I just don't like adjusting them. Go Solid. It'd be more fun.

The Morels seem to be a popular lifter for both hydraulic and solid roller applications. I know they're proven as well. GM just recently released these race style lifters and they're priced really well. I don't know if there's many people out there who have tried them to post claims/good luck with them. I guess you could solely go off of claims with the Cadillac race car or whatever they were designed for spinning 8,000 rpms.

So should I play it safe and stick with the Morels or give the GM race lifters a shot? Would you say these 2 lifters are at the top as in best?

Rocker arms, besides price, how come rebuild Harlan Sharp stock rockers are so popular? Are they better than aftermarket rocker arms that are offered? What this be the best way to go or is there something better, despite cost? I just don't want to do this twice. I want to make sure that I buy good proven parts that will handle my application.

Be wieght concious with a hydrualic roller. If you stay light you can run less spring which is easier on the lifter and is easier on the lifter roller. Its tough to beat the stock rocker arms fo wieght in a high RPM application. The weak point has been that roller bearing setup which apparently has some options for beefing up. If I were building an all out revver for 7500-8000 rpm i would look at the new LSK lobes Hollow stem valves stock rockers 3/8 pushrods titanium and good GM racing lifter or the morels. I would have the stock rocker arm bearing/trunion assmbly replaced with the upgraded roller steup avaibale from a few sponsors here and try to focus on wieght.A good spring will be mandatory maybae something pretty stiff but if you keep the valvetrian weight down you can back off the spring a ton.
