hum ill need to consider oiling. Its a toss up for me between the mantons or CHE. Leaning towards mantons only because its essentially oem style with better materials. Stockers are good for me since my ultimate goal is 750 to the wheels, so I'm not breaking records. But I want to build once and have it last until I die or wreck the car. lol. Damn engine building is expensive.

Why not just stock? Nothing has proven to be as good as stock. Either stay a stock rocker, or run a full out roller aftermarket $1000+ seutp.

I could be mistaken but I thought the reason most jumped off for other aftermarket options was the GM parts had issues and dropped needle bearings in the oil system / sump? Maybe that has since been corrected with newer parts OEM not sure but most input I see is CHE and Straub.

Only ones within a certain manufacturing window where the supplier provided faulty parts. The rest are perfectly fine. This is a case where people assume because its aftermarket it must be better than oem...

HOWEVER. If your cam lift is over 0.650 the stockers will not work properly on the wipe pattern.

The ONLY bad OEM rockers were installed in engines from January 07 through the end of the model year, July 07. ALL the rest were fine.

...probably by me. I'm one of the chief drum beaters.

It just amazes the crap out of me that people feel the compelling need to fix something that's not broken, especially with a "fix" that's much worse than what they think they're fixing.

I guess it's just a fix-ation...

Well I'm building a motor from ground up. All new. I think it's prudent to investigate if there are better options than stock. I'd like to build once. I'd like the tool steel of the mantons. Figured for longevity sake. Reality is the stockers are designed for 100k miles so I suspect I'm good with them. I only drive car 2500 a year...

What heads, what cam (lift, etc)?

outhouse

300,000 many going over 200k

Nothing in the 300 range keeps up., Katech still uses them.




You get up to the 800-3000 range, yes there are options but build type dictates which ones for intended useage.


For most 600 ish build the stocker are plenty.

Thanks for the question. Another concern is the cam and the stockers are designed for stock cams. So I though more durable trunnions would be better for higher lift cams.

Anyway if you can point me In the best direction that would be great. FYI I'm a c5z owner. I lurk here because a lot of parts and concepts interchange. I'm not looking to break records, 750 is goal want to be quasi streetable I mainly ride around with an occasional trip to the strip.

I'm building a Ls6 based 402. Block will be sent out soon to ERL mainly for their long liners. Callie's magnum xl crank with ls7 rods (they will be rebushed). Have these parts already.

Have 243 heads that have been ported by mamo with larger valves and dual springs w/ti retainers. Work of art. Also got his ported fast 102 with and ls2 90mm tb.

I'll have tony spec out a cam based on this set up with boost up to 6500 or 7000 rpm(haven't decided yet) so I don't know the cam specs. Shouldn't be too wild though.

Other than that it's basically just Pistons and assembly with associated parts that are left.

I figured stock ls7s are boosted and run up to 7k with 800-850 on here(or so claimed) so I'm thinking stockers (ls6 rockers ) should be just fine.

What say you? I appreciate your insight. I'm a relative novice.

Nosferatu333

I think you lost me. 300 range keeps up?

MTPZ06

I'm thinking roller tip rockers, and I'm thinking that Tony is the best guy to talk to about that...his heads, his cam. Just makes sense.

outhouse

No Rockers similar to the stockers price, can keep up with the stockers around 300 bucks

Nosferatu333

Right on. Makes since to me as well. I'll talk to him about rockers as well when I order cam. Was just thinking rollers hard hard core all out race engines. I'll hit tony up. Thanks again

Nosferatu333

Got it. Thanks

Closer to $200 if you shop around.
