hey guys I was ordering the 222/228 Lunati cam for cathedral heads. Ive been debating the swap. Order got screwed up cause back order. Should I just get a Lunati Ls3 spec cam?

Ill get new heads, plus I like the lift on this cam better

its a Lunati 60532

219/231 .625"/.651" on 112.

Let me know how those will work in a heavy Tahoe with L92 head swap for a Lq9.


Ok just got off the phone AGAIN.... that cam is back order too... damn Lunati!!!

so here give, Switched to a comp cam. The guy said he would match the specs, and he talked with both Lunati and comp, and he says this COMP cam will work tremendously well with the L92s...

Comp Cam 54-458-11

I like the specs better, and the lift is awesome compared to Lunati. L92 swap here I start...

Specs on the comp cam is

227/235 .614/.621 on a 113la 109 center

Not going to mill my L92 heads, just to be safe on the cam specs... Going with truck L92 intake

 

Better order a 4000 stall converter to go with it. No way I'd ever put a cam that big in a heavy Tahoe.

 

i dont think it would be too bad behind a 3,600 converter...i prefer cams on the larger side though. a ls1 with 226/226 112 felt perfectly fine behind a stock converter and 4.10 gears. i think a lot of setups leave a lot of low end power untapped in the tuning. it's easier to blame the cam instead of the tune.

 

hey Its prob going to be perfect. When I had a cam spec for my Tahoe L92 those were the specs, for my 3700 stall converter... I have a 3200 converter now, so I think It will still be fine...

If more is warranted I can switch to 4.10 gears.

I was going with the Lunati above, but deep down it was too small after being speced bigger cams for my 37-3800 tall combo. well we will see what happens... I think Ill like it, but we will see.

a cam that size was speced for my 3700 with 4.88s and 33s..

now Im runing 3200 stall, 3.73s, and 30s... more inline for performance.

 

well said, with my 3700 and 4.88s, I felt too much low end, thus wanting mid to upper rpms...

 

we need a "LIKE" button like on facebook because I love this post. I totally 100% agree. I love a bigger cam, and even behind a stock converter I never had any issue with a 224/228 in my '01 4.8L RCSB, and it had plenty of low end even for a 4.8L. 4.10s made a lot of the difference.

 

It'll have a ton of low end with that cam. Those cam specs are similar to mine in a 4x4 rcsb with a 402 and wcch l92's with a 3600 yank.

 

exactly from what I gather reading... this cam is for a 4.8 5.3 engine Comp says, with Cathedral heads on the website. But like I said we both talked with Comp on the phone, and its a bad *** Ls3 cam as well!

1900-7000 rpm range thats freaking nice! its going to be nasty son of a bitch. TQ should be good for a Tahoe. Still need HP to keep moving... Learned that with my 4.88s. Had a multitude of combos, and Ive found my way to this point.

Description: HYDRAULIC ROLLER-Good street/strip camshaft with wide range. Must have substantial airflow upgrades, inlet & exhaust.

109 centerline from what I read kick in the TQ even lower down early.

 

"Small Displacement or Max Torque, 4.8L-5.3L" from Comp website

Interesting... So I know this cam will be smaller in a 6.0
