hi well iv seen several people swap ls1's in abunch of f-bodies and mostly thirdgens but why dont people swap in the LS6's instead? come on plenty more power for barly any more price over the ls1. i know some people do mods like diffrent cam and then that will make since but some people just do the ls1 swap then leave it or add a supercharger and thats all. so anyone got a good reason why? 1 reson that i can think why is because some people get the engines out of wrecked f-bodies but there is still wrecked c5 z06's though.

The price is usually considerably more for the LS6. Plus, aside from minor block differences, and different pistons, the ls6 is basically an ls1 with a different top end. Most people don't want to spend the extra money, especially if they are going to change out the heads, cam and intake anyway. If you were doing a smog legal swap, then I agree the LS6 or LS3 would be a better choice. However, if you are actually wanting to go fast, an LS6 isn't worth the extra coin IMO.

a few of us are doing a ls6 swap. when i refer to it on threads i usually call it a ls1. it's really nothing different than a ls1. most usually upgrade to 243(ls6,ls2) heads or something better along with the cam. i just happened to find a good deal on one.

Well, mine is an LS6 crate but some people get pissy when you specify you have an LS6 so as ls6iroc said, some just call it an LS1. If you get a dropout of a z06 you have to figure out the accessories as most folks use the f-body ones. And as 1bdbrd said, the LS6 is much more expensive.

If you were considering a supercharger I would imagine the LS1 with its lower compression would be safer in stock form but that depends on your psi too. If you can get a good deal on an LS6 and you don't have any upgrade plans, go for it. If you have upgrade plans you might want to calculate the costs ahead of time on each engine.

when looking for your engine the better option is the 02 that year had about 25% of the f-body cars coming with the LS6 the only way you can tell is by the engine casting #s on the block which is located on the rear of the block just below the head can't remember what side its on. the only difference with the LS6 and this engine was the heads, cam, and windedge tray. and of coarse about a 100 hp. I swaped out the TPI I had to the LS1/6 and kept it stock its a great ride the way it is now good luck with what ever you do.

A lot of people swap regular LS1's instead of LS6's for the same reason I got an LQ4 instead of an LS2...I was not wanting to swap in a stock block. I went through the entire block and replaced literally every part in it. Why spend the extra money on an LS6 just to turn around and rebuild it to make more power anyways?

it all depends on what you are doing with the car if you go all out with high hp u end up breaking stuff all the time if u want a daily driver then your going to get more than you need with stock or with mild upgrades. for me this is all new putting the ls6 in my car seems the newest thing is putting a lsx in or better to get the higher hp now if you put the power to the ground with slicks u end up taking out the rear end I will say its now a fun ride but really enless you are racing it whats the point of more than is needed. lol

I think most points have been brought up already, but the way I see it:
-LS1's are easier to find. I don't see many LS6s in the yards around here
-less expensive. easier to find, more out there, drives price down
-power levels can be reached for little money
-we're all gonna tear em apart as soon as we get them , why spend extra on parts you're gonna swap anyway

99 and up ls1 is the best one to go with I have seen them for $1000 - $1500 depending on mileage and if your into standard there a little more. that is your call in the end they come stock with a minimum 325 rwhp and if you send the heads out and do a little porting and change the cam there is an easy 100 hp at minimal cost giving u 425 rwhp at that you will break all kinds of stuff good luck lol

I see a lot of questionable information on this thread, so I will try and help you out. I built a few LS1 and LS6s over the last 10 years and had some of the very first Power Adders for the C5.

What is the same.
1.) For one after 2001 there are no differences in the LS1 or LS6 block. Although the LS6 was the designation for the Z06...in late 2001 all of the Corvettes got the same block (case). The block (LS6) was re-cast to offer more rigidity and holes were cut into the block between the cylinder bays to promote better crankase ventilation between the bays. If you have a late model LS1 block it is identical to the LS6.

2.) Also from 2001 up the intakes are the same as and LS6 intake. So if you get an LS1 intake from an 01+ then you have an LS6 intake.

3.) The PCV was changed in 01 for both LS1 and LS6.

4.) The 01 LS6 has a different cam (a little more lift .525 to .550 and duration) then the 02 LS6. The 02 LS6 also got the sodium filled valves and better valve springs.

What is different (01+ LS1 and LS6)

The cam and heads are different....that's it! STOCK LS6 heads flow equally and perform as the majority of the Stage II LS1 heads offered by everybody.

01 LS6 385hp
02 LS6 404hp

01 LS1 350

Whoever is stating that the LS6 is significantly more expensive.....well... they must consider $499 for new/reconditioned LS6 heads that can be had on Ebay as "more expensive". I don't consider that significantly more exepensive..the LS6 heads are less then a SBC FI intake (HSR or Miniram) and add 40 hp....even less then LT 1 3/4 headers. The LS6 heads give that much hp using the same stock manifolds...so that should tell you something about bang for the buck. In the old days LS6 heads CNC'd Stage IIs were over $2K and you got no credit for an LS1 core...today you can buy them outright for $499 and get 40hp. What other mod gives you that?

LS1tech has a cam only Dyno Sticky......there are LS1s and LS6s with the same cam and the difference is about 30-40 rwhp.

Now if people are comparing the first Gen III (9-01) to the revised Gen III (01-04) then I can understand them stating more expensive. The 97-early 01 LS1s are different then the late 01-2004. Once again the only differences between a late year 01 LS1 and LS6 is the Heads and Cam.

I have a late model 01 LS1 with LPE GT2-3 cam for sale right now. I also have a set of AFR dual valve springs and ported Katech LS6 Oil Pump to go with it if somebody is looking for a newer motor. 20K miles...didn't burn a drop of oil.

Post your source for LS6 engines at prices close to LS1s.

That is assuming you have one. Because otherwise your post is nothing more than a typewritten version of my preschool kid's "Why is the sky blue?" thought process.

Hopefully you're a tad more mature than that, but the spelling makes me wonder.

well at gm performance website its 500 bucks more for the ls6, no if ya talking about engines i have a stock 305 tpi, and man i just turned 13 im not no spelling genius but i can do better trust me this is just like a rough draft or whatever ya wanna call it i have LOTS better spellin at school i figured some azz on a car website would tell me how to type its readable isnt it?

This thread has taken a 180* into the land of Epic Failuredom.

Actually, it was never that far from it from the start...

What one has to apply when it comes to cost the application of Economy to Scale. $500 to one person might be like $5 and to another it might be like $5K. This is why I tried to compare the HP per $$ figure for like mods.

On a TPI L98 car one would pay over $400 for an HSR that doesn't fit a Firebird without cutting the hood, or over $1K for a modified HSR or Miniram that will. The net result of that $400 spent is 40 hp...so 245hp to 285hp

With an LS1 (01+), for $1K...to add LS6 heads ($500) and then lets say spend the other 1/2 of that $1K ($500) for a cam. One is going to boost the hp level about 100hp....my 97 car with an LS6 Intake (because only 01+s have LS6 intakes) and the older block design, headers, pulley, and cam, made 430/400 rwhp (500bhp).

As stated if you have an 01+ LS1 it already has the new block (LS6) and LS6 intake. So with the Heads and a Cam for an additional $1K you are close to 475-500bhp for the same $$ spent.

Trust me on what I say...I have spent close to $100k in modifying to C5s..with H&C, Superchargers, and two different Twin Turbo kits. I have a shop at my house and do 90% of my own work. Click on my by sig to see pics.

isnt this a repost? he keeps posting similar topics

just egnor the negetive comments and keep to what the forum is here for

I salute your enthusiasm, but maybe it's time to hush up and focus on your studies.
