The ls motors are nearly identical to a ford block in every way. The 351 block is a copied design of a chevy small block. They use the same head bolt pattern spacing. Too bad you can't just swap on an intake and cam and call it a day.

Gm wiring is . I have never had to change or modify any wires on any ford I have owned. And that is all that I have driven. Now as far as work trucks. Having a single harness for the entire car with no connectors is stupid. Gm did this for many years. They also use a 14 guage wire for the alternator on every stock gm vehicle I have ever worked on. They purpousely use parts that change year to year and design them to not be backwards compatable.

When I'm working on a ford, rather then buying a new part, I can have it tested or swap it from any other similar era ford. With a 89 cavilier, there are three different sensors for that year, and none are compatible. When you buy a starter you have to play with shims just to get it to work.

As far as ease of use, price and repairability, I would go ford all the way. gm's have their place, as long as you don't mind paying more for parts that are less available and never have a wire go bad.

Ask thunder chicken about when he was working at a dealer ship and some one cut the wires out when they stole the stereo and he had to rip the entire car apart, because there was only one harness with no connectors.

Shadow a corvette just beat the record for the fastest 1/4 mile run of a 100% stock vehicle. Guess what motor it had. You got it an LS motor

you just answered part of it right there, corvettes.. i don't like any other car they came in either.. the biggest reason, everyone thinks it's cool to drop them in everything with 4 wheels.. i used to think they were pretty cool, outside of their original engine bays, until i saw 1 in an SS396 chevelle.. the sight of that motor under the hood of my favorite car made me sick

Shame maybe you should research the firing orders. Ford Copied Chevy. So i am going to ignore you rant.

LOL, Bob and weave. If you're going to tout the awesome ingenious of the LS engine every chance you get, (on a Ford forum particularly in unrelated subject matter) then be prepared to defend it.

Several years ago I used to fill up my car with it running until an old woman freaked out and complained to the gas station attendant that I was gonna blow us all up. The attendant agreed and told me over the intercom to shut my car off. I tried to explain that nothing was gonna happen, but it didn't matter. So after that I just started turning my car off.

The Generation III V-8 engines replaced the Gen II-LT family in 1997 and Gen I completely by 2003.

Pretty sure the Ford mod engines preceded 1997...by well, the better part of a decade.

Quote

The traditional five-bolt pentagonal cylinder head pattern was replaced with a square four-bolt design, and the pistons are of the flat-topped variety (in the LS1, LS2, LS3, LS6, LS7, LQ9 and L33), while all other variants, including the new LS9 received a dished version of the GM hypereutectic piston.

The windsor Ford engines first debuted in the 60's...unless the design was copied from the first version of the SBC...

Quote

The cylinder firing order was changed to 1-8-7-2-6-5-4-3, so that the LS series now corresponds to the firing pattern of other modern V8 engines (for example the Ford Modular V8).

It's the automotive field...copying other's designs is how things have been done since 1903. Get over yourselves. Breathe deep, hit the back button, and move on. :D

I've worked at GM dealers for most of my working life, and I can say from experience that GM fuel pumps suck... in TRUCKS. It seems GM has not been able to make a decent truck fuel pump in decades. I've replaced lots of 'em in all sizes, shapes and generations of trucks and SUV's from 1989 to the current generation. GM truck fuel tank sending units suck too.

GM wiring, on the other hand, has always been some of the best. Sure, GM has had some boneheaded wiring ideas (like mounting the PCM in the wheelwell of J-cars, right where the wheel is guaranteed to spray salt and shiznit all over them, a design flaw that resulted in several recalls), but for the most part GM wiring is robust. GM doesn't seem to have the module issues Dodge & Ford do either, and GM wiring diagrams are far and away the best out there, easy to follow when you do have a problem. Unfortunately this is changing with newer vehicles, with more and more computers in the vehicle causing more and more problems. $400 power window switches in Trailblazers comes to mind.

Haystack: That Caddy wiring harness thing was because that car was the first model year of that style, with a brand new style of radio, and was one of the first in the country. It's not uncommon for brand new vehicles to have new parts supply issues, especially when that new part is something you would not commonly replace. And where did you come up with the 351W being copied from the SBC? The two engines have nothing in common other than cylinder count and layout. The SBC head uses 5 bolts per cylinder compared to the Windsor's 4, so they certainly don't share head bolt patterns...

As for firing order, I'm too tired and don't care enough to look it up, but I wonder how firing orders would compare when one considers that Ford numbers their cylinders differently than GM (and everyone else). Ford numbers theirs front to back, bank to bank (IE pass side 1234, driver's 5678) while GM numbers them as they appear on the crankshaft (IE one bank is 1357, other is 2468)...

Ummm.... This started out as an interesting thread. Not sure how it became Ford vs Chitty. To figure out Ford and Chevy have same firing order if you re-number cylinders? Tom, you sir have waaay too much time on your hands.

We didn't experience the 10% ethanol thing here in Canada (to my knowledge) so I don't think that would be a factor in the truck pump failures i've seen (and if it was, it'd affect all fuel pumps, not just gm trucks). I think it's just because gm truck pumps suck. Maybe it's how they're mounted, perhaps their operating pressure and/or volume, but for some reason they fail, frequently and suddenly (and sometimes strangely - I've seen them refuse to work with less than 1/4 tank, likely from overheating). Never heard of fuel pumps dying due to cold fuel, though. If there was any fuel in the tank at all, the temperature change would be so gradual and the temperature difference so small (fuel kept underground stays at a fairly consistent temp year round) that I can't see it causing failure. Of course I live in a relatively cool climate, where the temp rarely goes above 90 (and rarely goes below zero in winter)...

I know gm uses suppliers to make their pumps, but in this case the suppliers suck ass. Gm wheel bearing suppliers suck too (gm vehicles have a horrid track record for wheel bearings, all models and spanning at least two decades). The cheapest supplier isn't always the best one...
