Hey guys i just bought a complety stock LT1 T/A and im looking for some advice.

instead of dumping a ton of mods on a stock motor like heads cam and boltons im looking to go straight to dropping in a built turnkey longblock.

im wondering if its worth the extra hassle swapping in a LS series motor, when it seems like once you pass a certain price tag the lsx and ltx are at the same power levels

for instance

lt1 making 634/750 at letting out at 5200 on a 100 shot before the recent rebuild which should add some new power (70hp claims) for $7,000

or this 408 making 550/505 n/a for $8,000

any reason i should drop the extra money on the LS plus all the extra money and hassle for all the time and parts needed for the swap

 

think about tunability,at that point the LsX shines much brighter!
i am in the process of this myself,i really love the LtX but when it comes down to it dollar for dollar you CANNOT beat the LsX,just look at what stock Ls6 heads can do with a small cam! when finally added up both motors done the way i want them the LsX was almost 1800.00 less and almost 100hp more sign of the times.................

 

The LS is newer, responds to mods better, has more of an aftermarket, easier to tune, easier to work on..

Thats what I've experienced with mine.

 

i understand the point of the LS1 responding much better to bolts ons, heads, cams, etc. but Im looking past that point and on to a fully built turnkey longblock so at that point it doesnt really matter as it wont be responding to mods sice its already built and you see the final whp

like i said if i was wanting a cam only car or just heads and cam car id swap in the ls1 put a ms4 in it and call it a day

but im looking at already built motors. as you can see in the links above the LT1 is just as good if not better than the lsx above for a thousand dollars less and minus all the pain of swapping over. and i have a tuner who can handle anything i can throw at him so the tunabilty isnt an issue

 

^ Sounds like you answered your own question. I personally would do the LS1 swap.

 

Because "letting out at 5200" usually means there were "issues" on the dyno.

Get used that owning an LT1. It's a sad truth.

 

yeah he said it was tuning issues that car started to get lean at that rpm

 

haha i guess this thread is more along the lines of
"convince me why i should spend the extra couple thousand on an LS1 and all the pain swaping it in. vs over a built LT1 making the same power"

lol easy terms :

LTx making 600 rwhp= direct swap right back into the car no hassle and cheaper
LSx making 600 rwhp = buying ls1 k member, steering rack, computer, all the wiring etc. plus the added cost


convince me why i should chose the ls1

 

i always loved the tq of the ltx , but comes with a lot more issues then a lsx.
I owned several of each over the years, I think the lsx would make more power with the same mods then thr ltx. A decent size cam only lsx with a 150 shot could get you 600rwhp. Theres tons of cam only lsx putting down 400+ to the wheels. Then again a properly built ltx could put donw some serious #'s as well

Either way you go you will have one fast motor

 

once again i agree but im not looking for cam only or a 150 shot

im comparing fully built 500 hp lsx vs fully built 500hp ltx n/a, which will both then be sprayed with a BIG shot.

 

Put the LSx in now and never look back...except to see the loosers who will still think you have a 'Slow' LTx car

 

Also consider these things that contribute to the cost of an LS1

ECM
Harness
K member


Just to name a few

 

thats what my point is. Is all the extra cost for the swap parts and the time and hassle to swap it worth it, when both motors are putting down the same rwhp?

 

This is what I spent on my swap parts to give you a rough idea..

PCM: $60
Harness: $200, built it myself to go into the Car.
LS1 Oil Pan: $150
LS1 Steering Rack: $50
LS1 Accessories & Brackets: $250
LS1 Starter: $110
LSX Conversion Mounts: $40

And if you go LS, you will have to put a Tranny behind it, I assume you are planning on a different Tranny anyways..

Yes there is an extra cost, but the way I look at is I have what I want, and I'll never have to try and sell my LT1 Camaro to buy an LS1 Camaro..I saved a **** ton of money in the long run.
And I get to laugh at the people I know with the $20K+ LS1 Car that can't mod them cause they can't afford to, they are stuck with payments. I have about $22k in mine, it's paid for, and it'll whip a $80K C6 Z06..

 

the car has a CPT race built 4l60 non electric so i believe it wil mount up to the ls1

 

LS1? The LT1 might as well be dead technology.

 

My 383 puts down 460rwhp with baby LT4 heads and only ran me 4500 INSTALLED. I did get an insane deal on the LT4 heads/intake so that did keep costs down.

IMO it's not worth the money to swap in an LS1. Build the LT1 right and it's a great powerplant.

 

Having a LT1 that whoops most ls1s is cooler. Since your going fully built I would stick with an LT1. Ive also had both but just love the LT1. Plus IMO LT1 cars should stay LT1 cars.

 

It will, just have to get the right Convertor.

 

thats what im thinking i dont see any benefit in swaping to an ls1 if both built motors are putting down the same hp and staying lt1 will be far less involved
