Did FORD design the LS engine?

That being said, as an example of contemporary Ford engineering, the spark plugs tend to break off in the heads of the 5.4 (or whatever is in the trucks) when removal is attempted. The broken plugs can't be removed without taking off the heads. The heads can't come off without the BODY BEING TAKEN OFF THE FRAME. I had heard about this before, but saw it with my own eyes a couple of weeks ago at my buddy's shop. Some poor slob had his truck sitting there, body lifted off the frame, heads off the block, probably spending a couple of thousand bucks, JUST TO CHANGE THE SPARK PLUGS.
Something that just plain could never happen on GM trucks with LS based motors.

no doubt the new 5.0 is a great motor....but its about time for us ford guys...i owned a 99 GT 35th anniversary with a built 4.6...it ran high 7's on motor in the 8th mile but it was an absolute nightmare to work on....to be honest, for the amount of work that was done to the car, it should have been alot faster
True enough back in the day, but now we're contending with the vicious Coyote 5.0 ...

Here is the picture he sent me of what he did. It actually didnt bolt right up but here is what he said "Ls1 head resting on 302 block screw drivers indicating head bolt locations, push rods thru heads and nearly resting on lifters"
"some ppl can't see the obvious resemblance they might not have copied Ford but its to much of a coincidence with the geometry and bolt locations"

Seriously, there are only so many ways to make a pushrod V8. If they look similar, well that's the nature of the beast. It would be like someone saying Ford did a horrible job coying the LT5 or Northstar with their 4v 4.6 V8 simply because they are OHC.

Uuummm No Noting of the LS motor is ford, they would like to claim it is just like we GM owners can claim there 289 motor is really a blue print motor they got from GM but the truth is most of the tech that is in the LS motor we will have to thank SAAB for, but since GM own SAAB at that time that means all new tech of the LS motors before the aftermarket companies got their hands on it is GM's all the way..... that's right SAAB Thank you

up until a few weeks ago i would have argued as well...LOL....but ive come to realize that stock ford pushrod SBF blocks are junk.....for the price of a bare SBF dart block i could build an entire LS based motor and make just as much if not more power......not brand loyalty...its just common sense

i used to make a killing doing cam and head swaps on Mod motors becuase nobody wanted to do them theirselves....i hated doing them but it waseasy money at 500 bux a pop......the timing chain setup is total garbage and each one i worked on had something different between the romeo and windsor setups.......
And not multiple timing chains with not timing marks[/QUOTE]

Fucken Old Rotten Dodge
thats all I gotto contribute other than I like the little lsx engine over the wide as in fill your whole engine bay and then some mod motor.
Oh and dont forget the GM v6 engineered about the same time as the LSX , series 2 3800 - quickest one of them with stock block and rotating assembly has been 8.6 @159 in a street registerred FWD car (ZZPerformance) before I got into LSX cars I was into 3800 SC cars ( still have a couple) and it was always fun picking on the v8 mustangs with my stock internals 4 door fwd little 6 banger
GM FTW mid 90's to late 2000's now ford is making some nasty engines and the mustangs are lighter than the camaros so its a real rivalry again at this point - Ford hasnt been on top of Chevy in the street wars since the original 5.0's 20 years ago and anyone with a couple tweaks on a t type or GN owned them lol so still GM FTW
