dude i havent seen any ls1's with 800 flywheel horse power the only one ive seen or heard about even close to that is the S.A.M ss but hey i could be wrong and you would need to run a bigger bore have to put sleeves in the block more cubic inches too.

Aftermarket parts... Do it right the first time you don't have to do it again. Who here has built motors for more than 10 years? My guess... Not many. If and when the experience level gets there then anybody can give their honest opinion. Until then I will believe him. 780 RWHP I believe this one is only 330 Cubes.

I fail to see how a old school small block Mopar with dual carbs in a 60's Belvidere has much in common with a Gen III LS1 engine except that they're both pushrod V8's. What kinds of LS1 motors has he built? Doesn't sound like any to me otherwise he or you would have mentioned it. Personally I wouldn't let anyone that doesn't have any experience working on these engines build one for me. I find it humorous with all these old school guys that think they know everything even though they've never even worked on some of the newer engines.

You asked our opinions on what we thought, so that's all we're doing is giving opinions. If you don't want to read them or listen to them then don't ask!

Well then why are you wasting everyone's time coming on here and asking opinions? Next time why don't you put the disclaimer in your post that if you haven't been building race engines for 10 years then please don't give your opinion.

Yeah no kidding. I know of a few folks who build Mopar stuff and it flys, but what does it have to do with us?

To the earlier post about alky, I'm not personally knowledgeable about water/alky setups so I will stand behind my earlier comment say that you can make 700rwhp with 110 leaded I have seen it done on like 6-7 LS1 and LT1 setups. I think that 104 unleaded might fall a little short.

Didnt harlans make over 800rwhp shutting down early, but I'm sure he was running 116?

I think when Harldoggg hit 810rwhp it was with C16 (117 leaded).

I love my LS1 Probably wouldn't trade it for anything. But, If the LS1 is supposed to be this great motor, Why only 800HP? The comparison is, If this builder can make 780HP with 40 year old technology and 330 Cubes on 110 fuel, Why isn't the ls1 making more? Just not possible or Just not enough experience? Not trying to start a fight here. Just actual opinions, not Sh*t talking saying no way in hell.

The 330 is the designation for post-type sedan that Chrysler used for the Belvedere. In the engine bay is a Gen-U-Wine RB block and, at a guess, I'd say it's a 4.380" bore and a MP 4.150" stroker making 500 cubes.

Can't say much for the crossram, he can make more power with an Indy intake and a single "Flying Toilet Bowl." 780rwhp is respectable for a 500 ci n/a engine (assuming no N2O), though certainly not streetable, nor a daily driver. The crossram was horrendous at keeping fuel in suspension, so PT driving was, let's say non-existent.

I love that car, though. Do you have more pics?

As far as the LS1, if this person has no experience with LS1/6 engines, he's simply a babe in the woods. The LS1/6 is that different. Sure, the shortblock (sans cam) is a no brainer, but that doesn't make hp, it only supports it.

You'd be better off going to someone who's made a dozen or so live at very high hp levels. It's just not your average smallblock.

The LS1/6 does have one thing in common with BB Chryslers and BB Buicks, though... they're all VERY expensive to build relative to the old SBC or SBF.

JF WS6

Read SS00BLUE's post, very good post. And also I'd say the answer is that the LS1 is still fairly new and there isn't enough experience/aftermarket support or $$ to push people to build extremely high levels of power or even a REASON to. This question has been asked several times. If there was a LS1 racing series that had considerable prize money and sponsorships I'm sure you'd see some big developments with this engine. I believe the ability is absolutely possible, but there needs to be a lot more time and money invested in R&D to do it.

Cal99SS just got I guess he never built one of those before in his ten years or so.

Wait Wait a minute , isnt the ls1 346 cubic inches where do you get this 330 cubic inches and besides who is this guy that says he can build his motor let me get his name and do some research on it. Ohh ohh the ls1 is probably the best production motor not the best motor of all time a sbc or bbc will whoop it good. I love the ls1 its great for steet appilications and with mods you can make a good 10, 11,12 secoend car but like i said i dont think you can have that much power on that aluminum block without serious money at least 10 to 30 grand but hey like i said before i could be wrong if anyone has got any proof i would like to see.

Harlan made 810 RWHP and it was on C16, but that was with only 12 pounds of boost. Even if he was running a ton of timing, you can just back out some timing and add some boost to make up for it, and I'm sure you can make that much power on pump gas. Only question is, do you want to risk a high-dollar motor to pump gas?

SS00Blue

Heh heh. Easy, big Geoff. I wasn't out to own anyone. I just love 60's muscle so I know some stuff. But not much, as you already know.

Gotta read the post to understand what he said.

We'll see after the same 45 years it took the SBC/BBC to get to it's present level. Needs time.

I agree that 800fwhp can be made. Good point on pump gas. Alky is good insurance.

Plenty of those around, all technicalities and no Heart.
Same goes for anyone planning to make a quick buck by exploiting fans of a car you find " Below you "
this goes for all kinds of people in the world .

So what do you think of import racers? So many people give them Sh*t for liking what they like. If it goes fast, I give credit where credit is due. If you can make 900 HP out of a Cavlier more power to you. You have a 9 sec Honda Holy Sh*t. But accusing someone of having no heart, that is just plain ignorant. Most of the time lack of money is confused with lack of heart.

ChevyNo1

John, I thought M6's were in the range of 15% . . . and A4 around 18%. Where do you get the 10% figure from?

JF WS6

So what about import racers? Yah, maybe some domestic guys give them sh*t but they give us just as much sh*t in return. I pulled into a parking lot this last summer and had some *** clown standing in the parking lot tell me that he could put $3K into a stock Honda Civic and it would smoke my *** - this is with my car cackling through open exhaust with a big cam, ported LS6 heads and ET Streets/skinnies on it and pushing 440+RWHP.

I don't think anyone would bash a guy with a true 900HP import. The ones that get bashed are the retards in my previous example.

BTW, the reference to having no heart was to your "engine builder" who thinks LS1 based engines "suck" and are beneath him.

i've seen anywhere from 10-18% for T56 transmissions, but think about it. Could a T56 be 18% and a T400 non lockup could be 20-25? Does not make sense to me.

I view a T400 non l/u as being around a 20% loss, so I think a T56 is like 10%, just my opinion but I think there should be a spread.

How about 701RWHP? Pump Gas! Very streetable! And we have to deal with dyno style emissions!
