The LS1 block is 53 lbs lighter than an LT1 and the full engine is 66 lbs lighter than an LT1. If you want to get rid of the AC maybe another 40-50 lbs but you could have removed it from your LT1 or L98 anyway. There's no way the LS1 will drop 200-300 lbs off the front end by itself. Anything else you remove to get that weight reduction, like pollution equipment ..., could also be removed from the L98 or LT1.

It would still be a nice swap if you like the C4 body over the C5. :thumbs:

 

I agree :yesnod: What happen to LT1/4 to LS1 conversion :confused:

 

Not knocking this guys business or anything. The LS1 is a pretty good motor. I prefer the LT1/4 though. It'll make the same power as the LS1, it just takes a little more cam and stuff to do it. If your L98 or crossfire breaks and you have to have a motor swap done anyways and still pass smog this seems like a reasonable option though.

 

hey guys i completely understand where your all coming from. I just sat down and thought about it and heres my weights savings on a 85 vette ls1 swap.

Shortblock = 55 lbs lighter (55 total)
Heads = approx 60 lbs lighter (i just remember we went from 85 iron heads) so thats 115 lbs.
TPI setup to plastic intake = 28 lbs lighter 143 lbs total
aluminum water pump = 8 lbs 151
Factory lightweight ministarter = 10 lbs 161
factory exhaust manifolds to headers 8 lbs 169
Removing A/C compressor, condensor, a/c blower box 47 lbs 216
Also, removed the aircleaner assembly etc 3 lbs 219
no distributor 4 lbs 223

Im not exact on all of this...but from weighing the 85 swap before and after we went from 3120 to 2830 (no exhaust open header) and 2880 with exhaust.


So we lost about 240 lbs off the nose...

 

Why would you ruin an LT4 car by putting an LS1 in??

Don't get me wrong...LS1 is a great engine, but I wouldn't pay $9k for one when I could build a small block to get the same or more HP for less.

 

:lurk: I think it's a good deal. I own an 01 LS1 6-spd and a 95 LT1 6-spd. What would you spend to buy a C5? The LS1 is AWESOME! Where's your 6-spd, TUNER?

i am in no way related to this guy and i do not agree with the weight savings he is talking about at all but i am saying the ls1 motor and its cousins the 6.0 litre and stroker ls1 based motors are far superior to the current small block chevt we all have i have been telling a few buddys of mine that these ls1 based motors are just in the infacy stages there are numerous ls1s in the 10s realtively easy and stroker ls1s in the 9s on the motor an conventional small block will be 1/2-1 second behind all else being equal the heads alone are killer they can flow 300 cfm without even a sweat my heads on my motor are lucky to get 260 cfm and 300 is a big pipe dream all that said the ls1 is a very sensible swap for all out performance :cheers:

 

Corkvette1, the LS1 is indeed a strong motor. It has alot of potential. The SBC has years of experience and research behind it though. The LS1 has 15 degree heads right from the factory so thats where most of the difference comes from.

 

I, too am interested in answers to 1-3, 5 & 6.

Plus:,
7. Are any durability mods made further along the
drivetrain as part of the featured swap?
8. Are cooling system upgrades necessary/included?
9. Does the swap in any way reduce torsional chassis stiffness?
10. Can an R-D Cross Bar be retained post-swap?
11. Is it possible & economically feasible to restore the car
to stock condition (when C4 prices skyrocket in 20 yrs)?

And can you clairify what happens to the existing
eng/trans for $9g. Am I right that I have the option
of keeping them at this price or negotiating a lower
price and leaving the parts that come out with you.

Finally, can you speak to the visual end result.
Are the fab work, wire harness and plumbing changes
at a level that welcomes close inspection by critics.
Or is it better to keep the hood closed and just
collect pink slips?

To help answer some questions:

1) These engines are warrenty covered from wrecked f-body 98-02 camaro/firebirds. The cars are high damage accidents. and the complete motor/tranny is removed.
2) often motors in the 10-20k mile range are available from 00-02's so those are used. the 98-00's can save you a little money if you dont mind 40-60k miles on them as well.
3)yes there is a warrenty on parts and some work
4)smog legality is available. Please email me at ls1tuner@hotmail.com for details
5) The car is ready for pickup approx 30 days from the day it is dropped off or arrives here.
6) Bakersfield, CA

7) No durability issues whatsoever known at this time. We do not recommend dragradial or slick usage on Dana 36 cars
8)No cooling system issues seen
9) no, there is no loss of chassis stiffness or handling etc
10) What is a R-D cross bar?
11) There is no cutting on the car or anything that would keep you from swapping back the factory engine etc


You keep all your stock parts if you want. we dont take anything as core etc. We can reduce the price and take off the value of your engine/tranny toward the ls1 swap cost.

Yes the motor installed looks extremely clean, and gets HUGE attention by people. Ive heard no complaints on anything. With z06 fuel rail covers the motor looks very nice.

 

I think this is a fantastic deal! I wish I would have known about you guys before I did the rebuild.

What kind of cam do you guys use with the 475hp package? Who ports the heads?

Do you have any pictures of your customer's rides?

 

Did you remeber at l98/lt1 are basicly from 50s drawingboard compared to LS1 wich best ever V8 made.

 

LS1Tuner,
You wouldn't happen to have any pics of the two swaps done thus far would you?

 

:withstupid:

 

heck, if i was going to get a c5 and trade in my vette, it would cost me double the price and less HP then just swapping the engines. i think it's great deal.

 

Hi all is this option still there with the packages offered?
