I 100% agree, I flog the **** out of my old *** lt1 and it never misses a beat. 140k~ when I got it and atleast 1 WOT first and second gear pull daily for almost 2 years and 20k miles sense I bought it.

Maybe a 50k miles LS1 M6 may dyno 60rwhp more then a 175k neglected stock auto LT1, but at least compare the same drivetrains
.It's more like 35-40 rwhp, and it responds better to mods as well.
It's surely an uphill battle for an LT1 to hang with a similar LS, but don't make it sound like its a B16 vs LS3. A mild bolt-on LT1 can EASILY beat a stock LS1.

My full weight auto (3.23) LT1 vert weighed 3800 lbs with 1/6 of a tank at a transfer station (with me in it). Not sure how accurate that is but picture a full weight car + 150 lb me.
Has run a best of 13.78 @ 100 mph on a 2.03 60' with a +700 DA on 10 year old Continental tires, spinning while shifting. Mods are in sig. Still on stock manifolds and many year old opti. Spark plugs haven't been replaced in 8+ years.

No an LS1 easily puts 50 hp on an lt1. I have owned/ran both bone stock. With my 93 z28 I ran a best of 14.3@97 with k&n, 275 tires, and an ss hood on a 2.02 60ft. After than I did hot cam, small stall, and few bolt-ons and ran mid-low 13's. When I bought my LS BONE STOCK down to paper filter, and shitty 245 tires I ran a 13.5@103.5 on a 2.08 60ft. D/A was about 2500 both runs from lt1 to ls1. I've also raced my friends full bolt-on cammed 97 transam when I only had tune and a few bolt-ons and I would pull him a good amount. I have worked on many lt1 cars and I've seen what they run and I have raced many many lt1's. **** 3 of my good friends have had lt1's for years and I used to be the one in the bolt-on lt1 car running stock ls1's getting pulled. Yes lt1's can keep up to about 50mhp and than the LS goes bye bye fast. A MILD BOLT-ON LT1 SHOULD NOT BEAT A STOCK LS1. SORRY THATS THE FACTS. Coming from someone who has owned both and is really not biased. Just putting it how it is. Even when I owned my LT1 I knew how it was. Me and my lt1 buddies were getting pulled by ls1's everywhere. Except everynow and than you would find a dumbass that couldn't drive and you would hang with them tell the top end
Not sure what was going on there, but if I had a cammed LT1 run a mid 13 I would burn it right there at the end of the track. Nevermind a cammed/full bolt on LT get pulled by a mild bolt-on/tune LS1
.That's pretty slow unless it's a 2.73 auto car.

Looks like your personal bad experience with a lemon has clouded your judgement. FWIW my 93 auto ran 13.9 with stock with 140k on the clock, and I considered that average...if not on the slow side. Never ran it with "mild" bolt-ons, but it was more then half a second faster then your cammed LT1 with "most" bolt-ons.
Not sure what was going on there, but if I had a cammed LT1 run a mid 13 I would burn it right there at the end of the track. Nevermind a cammed/full bolt on LT get pulled by a mild bolt-on/tune LS1.
I guess LT1s just get slower every year while LS1 times stay the same.

. I had to replace opti's on that car 3 times and the 700r4 sucked nuts. Not to mention half the lt1's I see don't run right when it's really cold and ****. I spent half the time driving the car and half the time fixing it. Than I got the ls1 and I spend all my time driving the car or modding it 
. Scene my friends go through the same **** with the damn lt1's and I'm just not a fan of them. They are ok motors. They are strong as long as you don't get any water on them. **** my dads old 96 collectors edition vette never missed a beat, but that also had the lt1 with alot of the opti upgrades and ****. I would say the 95-97 LT1's arent horrible and stay away from the older ones. Not to mention the weak 2 bolt main. I'm happy with my 6 bolt main on my LS1

Maybe lt1's around here are just shitty lol idk. My car has always ran very well. No one over here thinks it is bolt-on only. The d/a over is high though. Wich is why my lt1 ran 14.3. Im sure it would have ran .4 tenths faster at a track at sea level. Plus my LS runs very healthy. I'm sure if I would have ran it at sea level stock it would have been a very low 13 sec car. Guess it's hard for me to like a motor that quits running when you drive through a puddle of water . I had to replace opti's on that car 3 times and the 700r4 sucked nuts.

One of the first things I did to my LT1 was drill the cap and run a vent line into the intake. It hadn't given me any problems, but I was always worried about it. Its a horrible design...I was very happy when MSD released their vented conversion cap, since it allowed the 92-94 guys to get a vented opti without needing a new cam dowel, timing cover, and opti for the conversion.
