As long as it hasn’t had the piss run out of it, has had the valve issue fixed in the heads, regular maintenance, there is no reason why it shouldn’t last more than 100,000 miles

[@carado1984]

Something is off about that one.

[@Ballen1182]

My '98 ls1 lasted 240k miles after countless hard pulls. Piston rings on cylinder 1 did it in.

[@eddiefender100]

Fixing the valve issue will modify the engine and therefore it will no longer be stock

[@carado1984]

@@eddiefender100 That's not a real sentence.

[@eddiefender100]

@@carado1984 got a point haha I’ll fix that

[@andrelongchamps5668]

heck of a lot of smoke coming out of that thing

[@JayRollaTSi]

Agreed. Just dynoed my 150k CTS-V that made 600whp/630wtq and blew zero smoke. I was actually surprised.

[@mikecrevier5811]

She's a dirty old street fighter, keep the oil up and burn a few sets of tires off. Best case it'll need a top end in the future. There's no point in being shy with a 100 on the OD 🎉

[@Camaro254]

You need to do a compression test, seems like you have a cylinder that's leaking compression.

[@donalddondero4402]

Definitely something was up with that LS7. That thing was smoking like a banshee lol

[@fishbone1537]

I was about to say then yo said it at the end. Never dropped a valve in those miles it has. I picture a older guy who dove it year round and never revd above 6k

[@Corvette_pilot]

I got a Vararam that’s been sitting in my garage for over a year now! I gotta get around to installing that thing one day soon! 🤔

[@icantfindausernamify]

Theres a guy on facebook who has 230k miles on his LS7. It does have head work done to it

[@Tony-ge2hj]

I would have spent the money fixing the ring issue(most likely) rather than adding mods to the car.

[@windycitywarrior71]

I’ll be freaking out of how much smoke is pouring of the back of mine.

[@bobsmoot8454]

If maintained and dropped valve resolved, an American engine should easily go 300,000+ miles before popping the heads, I’ve seen many V8s go over 500k without issues, but you have to maintain the car. Trannies blowup between 200-225k in my experience, but engines just keep going.

[@srtlat38]

Always wonder why they never replace the balancer with any of their packages? Maybe only of the customer requested it I guess

[@nitrousstang]

i got 2006 zo6 with 105k on it untouched heads fully stock

[@Tyla654]

Congrats on your hand grenade that hasn't blown up yet

[@jacksonshore5677]

@@Tyla654lmfao. he fixes the heads hell be fine until then yes a hand grenade

[@JayRollaTSi]

I was surprised when i dynoed my 150k mile LSA and had no smoke. Burns maybe 1/4 quart per 5000 miles.

[@nickadkins7765]

Not addressing the smoking issue is kind of concerning....unless you discussed it with the customer and he said send it anyways, but you guys are usually very transparent so I figured you would've mentioned that in the video if that were the case. I'd be pissed if you let me spend that kinda money on a performance package and it cane back smoking like a chimney 😂

[@regsmith7604]

That VaraRam intake is a bad MF-er! I had one on my ‘08 Coupe. For years I never 👎🏽 had a problem smogging it. But then, a hating ass shop had me put the OE intake back on to smog. They were petty haters.

[@tommyZ06]

my head hurts watching this with all the background shop noise!

[@brown723369]

Which is why I understand getting a baseline number first before any mods…

[@mjslatermichael]

Fran did say it was running kind of rich

[@someonewithabmw]

I broke 100k miles in my Z06 while pushing 9 psi with an F1A-94 into the stock bottom end. 🤷‍♂

[@malikharvey2303]

looks like piston rings will be needed in his future, looks like the Camaro I just brought

[@Vetteman372]

yes 100%

[@robertbull6248]

It will be back for a short block soon 😢

[@rle1020]

Show the cam bearings.

[@srmurc6zo6]

Is there any coating left on the rods?

[@TBagr]

Still smoking like a chimney

[@GETLITUP69]

Funny how no one addressed that in the video.

[@96t5wagon]

@@GETLITUP69??? They said it in the 1st :50 seconds

[@JayRollaTSi]

​@@96t5wagonthey said it was rich but never said anything after they leaned it and still smoking.

[@j.hackett3273]

Fran said to like and comment… So the camera kid didn’t know what a noun or verb was? New segment idea: “What does Garrett know?”

[@carado1984]

I cringe at how dumb this guy sounds.

[@thegonz7833]

What cost more the car or the build?

[@WildEngineering]

seems like quite a bit of blowby out the exhaust

[@marklagasse2012]

Is there any difference power or performance wise for 1 7/8 vs 2” headers? Kooks vs ARH is availability vs preference I’m sure. I see stage 3 is 1 7/8 listed now

[@JayRollaTSi]

Not much unless boosted .

[@carado1984]

One of if not their highest stage 4 has 1 7/8 and is around 650-660 on their dyno

[@nickb289]

Is there a point with mileage that you recommend freshening the bearings, pistons and rings before a top end upgrade?

[@RaceProvenMotorsports]

Probably 100k haha

[@Justin-bz1dp]

​@@RaceProvenMotorsportshi

[@jplperformance9073]

Still good #'s . I wonder why baseline was sooo low??

[@JayRollaTSi]

I don't see why they thought it was low. 505hp stock, 15% loss is 430whp.

[@Yellow_Car_Bad]

@@JayRollaTSithat’s low. They usually baseline 460-480 stock

[@carado1984]

@@JayRollaTSi and they don't lose 15%. It's 30-40 low on their dyno

[@JayRollaTSi]

​​@@carado1984your right. Forgot how high theirs reads. Probably has low compression on a piston with all that blowby

[@travisrenaker2851]

Can we not get as much Fran an more of the guys working on the cars. They are funny as hell. Matt is the goat. He makes the shop funny as hell.

[@Toroazul54]

160+ isn't a bad deal

[@dukenukem7183]

Black smoke matters

[@CPAJayhawk]

We are talking about a small block Chevy lol…

[@tommyZ06]

i bet most of the problematic LS7s are beat on without oil being up to temp, and are lugged without mercy in top gear

[@midlifecars]

Those rings are shot…way too much oil coming out of the exhaust, definitely would be pushing the customer to rebuild and warn him. That thing likely won’t last long like that

[@saqibj7962]

Kinda lost me with it smoking so much
