How many have de-modded or considering?
After I installed that, I was suprised that the valvetrain noise continued. At this point, I tried 3 different kinds of rockers, but no help. I firgured the chewed up cam must have put shavings into the rod bearings, so I had a used LS6 shortblock installed, with the same AFR setup. Surprise again, still a lot of valvetrain noise.
Figuring, the XER lobes of the cam were making the noise, I went with a VHP 228/232 112 cam with only .551 lift, but used 1.8 roller rockers. Still valvetrain noise. Next, I went back to the 224/228 (because I didn't like the 112 LSA) but installed Morel lifters. Still valvetrain noise.
I realize now, the valvetrain noise is the nature of the beast, but I can't take it anymore. I just can't. Next up, I'm going back to a Lunati (55003) cam that has a much less agressive lobe and lift (but I may reuse the 1.8 rockers again). I know I'll be giving up about 40 rwhp/rwtq but it sucks driving around hating how your car sounds.
My guess is that I've spent close to $15,000 in all this. On the good side though, I've blown a lot of challengers away on the road, learned how to rebuild an engine, and have a lot of cool tools!
You would have hated to old days where we were all running solid lifter cams and they sounded like typewriters...I love that sound...but I am old school..a 1970 Corvette with the LT1 (350 cu. in. 370 HP) motor idleing is music to my ears..or any of the old fuel injected 327s with solids lifters made the same sounds .. nice lope and the lifters making that noise is one of my favorite tunes..

one of my old toys was a 70 roadrunner with a built 440 big block with a big solid roller cam.. god I loved listenin to that car, and well.. driving an old car that like that went 10.56s in the 1/4 was awful fun.
I LOVE the sound of a big ole cam thumpin away, open headers or full exhaust... my old man is almost 60 now and he STILL loves it, has 496 ci big block in his 71 duster SICK.
That's why I bought another car for my regular everyday things around town where I don't want to disturb the peace

Without fail, the rattles, stiff susp. and constant drum of a powerhouse motor breathing through remotely street leagal exhaust system will fade or, at a minimum, become less concerning when the thrust from the tires meeting the pavement slams you to the back of the seat and the burst of loud exhaust noise fills your soul as the peddal slams to the floor. Some would recon it to that of favorite ride at the fair .. fast and furious indeed.
To some us, it's our chance to champion a heritage nearly lost. A heritage of GM muscle ... American muscle! Abandoned by our youth for foriegn ... "zing". It's a "wake up call" when our cousin and life long nemisis, the Mustang has become a sight for sore eyes along the highway. In order to "represent" where it counts .. bring your modded F-Body, bring the THUNDER .. bring the best!
If a quiet ride down the highway is what you want ... I would HIGHLY recomend the Grand Prix ... very nice ride
De-mod .. NEVER!!

I had a forged bottom end built so I could run the big boost but kept the stock cam, stock heads, ls6 intake & TB. I ran a 4" catback with a magnaflow muffler. it was so close to driving a bone stock WS6 but then hit the gas and the car would pull till next week. it was great driving 2 hours home from GMR and I didnt get a headache and my ears werent bleeding.
