ls1 swap

Michael Yount · Nov 17, 2004

There are a couple of guys out there that have dropped the LS1's in Volvos, as well as just about anything else you can imagine. Next, you're gonna start seeing the new hemis showing up in everything.

I think the ultimate expression of "American" is knowing you have the freedom to buy whatever you like, and drop whatever engine in it you want to. Don't give a thought to what someone else thinks - they can build/choose their car. Do what you like. Millions have fought and died so you could do just that.

I agree, it just doesn't seem right to put a Chevy motor in a Ford vehicle. I'm not sure why, but it just doesn't seem like the right thing to do.

It would be interesting to see, however. Very unique!

yeah, the ls1 is not a 350, more like a 346 or something. 5.3-327, 5.7-350.

i don't think a 4.8 is an ls1, just a small engine. could that be the old 283 that chevy made way back when.

Michael Yount · Nov 18, 2004

dastang - you can't just look at the size of the engine. The LS1 architecture (similar block, heads, igntion, efi system) is used on a variety of engines of different sizes in the GM lineup of cars and trucks. Very similar to the 4.6 and 5.4L mod motors by Ford; or the 3.7L, 4.3L, 4.8L, 5.0L pushrod engines by Ford - more commonly known as the 221, 260, 289 and 302. Different displacements; same architecture.

Michael, I know that the LS came out in 97'. I am not that naive and I am sorry if anybody understood it that way. What I meant was that the whole base of the sbc design came from the slow evolution of the 327/350 which the LS1 is one of the final product. As I mentioned earlier they are no joke. I may perceive mixmatched car parts as wrong for no valid reason but you do have a point. It is your car to do as you please... whatever floats your boat and as long as you are pleased with it is all that matters. Coming to a Ford forum with that sort of statment is going to get some responses... I was just voicing mine.

actually you dont have that freedom, not with smog laws.

i didnt know all the new chevy vortec motors were called ls1's, but i sure do know my buddy's 2003 4.8 truck will RUN it shifts a 6,000

TrickStang37 · Nov 18, 2004

the Gen III motors are reversed cooled? I know the LT1 is but i thought that idea was scrapped with the LT1?

dastang2 · Nov 18, 2004

i was thinking that the real ls1 motor in the vettes were in a different engine family. alls i know it my grandma has a 97 3 door truck with a vortech 350 and my mom has a c5 vette. i drove both and the vette is way faster than the truck is. i know it is a truck and much heavier but still. so is that ls1 in the same engine family

TrickStang37 · Nov 18, 2004

i know the vortech heads are basically LT1 heads but iron and are mounted on a Gen I block. and you also need to run different valve covers other than the regular Gen I stuff to clear the rocker arms on the heads as well.

Michael Yount · Nov 18, 2004

I'm with you Kevin. That's what the forums are all about. What I see differently however is the LS1 development history. While it is a pushrod 90 degree V8, that's about all it shares in terms of genetics with the LT1/small block Chevy. GM pulled out a clean sheet of paper with the LS1 and started over. To relate the LS1 and the previous line of small block Chevys to me would be like calling Chrysler's new hemi an evolution of the old hemi. In my opinion they're related only by brand.

Now, I would call the LT1 the 40 year evolution of the small block Chevy, just as the 5.0L was Ford's 30 year evolution of the 221/260 that saw light in the early 60's.

Enough.

Sicarius428 · Nov 18, 2004

Very true... Very true... I see what you are saying. I saw the LS improvements as a biproduct of all the shortcomings of the LT. To classify the two in the same lineage would be unfair.

If you want to build a LS1 for your car, trying to rip one out of a vette, or F-body might cost a lot because of what it came out of ("that be a vette motor boy") No, all you need to get the expensive part is find any GM with a Gen III SBC, which is what the LS series engine is. All 97+ Vettes, 98+ F-bodies, 99+ Silverado series pickups. There are several, the 4.8, 5.3, 5.7, and 6.0. The '01+ 6.0 is a real good bargain because they had aluminum heads that flow similar to the LS6 heads, pre '01 many had iron heads. The truck intake flows like the LS6 also, the reason there is a difference between the truck and car intakes is because the truck intake would not fit under the hood of a F-body or Vette, but it would work great under a cowl hood of a Mustang.

Me Three. They all have potential, the advantage with the LS1 is the fact from the factory it's already pretty stout, the ford motor is going to need some work. If your starting from scratch, it's a toss up for the most part. Parts for the 351 will be cheaper. The only real advatages the LS1 motor has is the aluminum block, which you could get from dart for the ford, and the reverse flow cooling system where you could run more compression, the rest is all in how it is built.

I did, but I ain't givin up my 5.0. My truck has a LS1 in it, but it has a steel block, less bore and stoke, but I'll tell you it moves the truck. While most truck motors tend to fall off after 4000rmp, my truck's motor starts pulling harder but the tranny shifts at 5300 and I wish it would stay in gear longer because it just contiues pulling harder. Mine is only the 4.8, but in a regular cab short bed. I have read they run mid-low 15's bone stock with that confuguration, the 5.3 runs high 14's stock.

Hey if you want the trans in your truck to shift higher go get a hypertech power programer. they work my friend has one for his 03 S-10 4.3 and you can change alot, you can make your rev and speed limiter higher to and some other cool thiangs, bad news it's $350 plus

TrickStang37 - "actually you dont have that freedom, not with smog laws."

Sure you do - you're free to pick and move anyplace in the country you want; and there are plenty of places where you have a great deal of leeway as to how those laws are interpreted and enforced. I believe you've confused a lack of freedom with specific choices that are made. Granted, the time may come when all parts of the country are saddled with more rigidly enforced emissions constraints, but we're not there yet.

Dastang - I believe if you read all the posts you'll see the trucks didn't start getting the new architecture small blocks until a few years after the Vettes - 98 I think. Don't know how to break this to you - even with the LS1 based motor in the truck, the Vette's gonna be a good bit quicker than the truck.
