Oh man, I have a friend that argues that an LS was copied from Ford. Damn, that’s laughable.
If GM ‘copied’ Ford for its firing order, then …. I’ll eat my hat. I’ll go out on a limb to guess that they might have done some testing to determine a better firing order than the previous SBC firing order they developed in the late 50’s. I don’t think they changed the entire SB platform by copying someone or everyone else.
I've heard it a few times myself.
Now, I've also heard some SBF design elements were themselves first found in other makes as well.
If, IF, someone cared enough to do the hard research with exact dates they could probably sell it as a paid article to some of the car sites/newswhores. (Yes, sp intentional)
However, nothing LS-related is worth that bandwidth to me energywise. And, like the LS engines, I find the coyotes also sound like **** with just about every exhaust I've heard from outside a car/windows down.
