Can we get along now? Summit has LS firing order cams

That SBC cam would be badass in a Motown block motor. Good and cheap LS heads roller cam with the cheap SBC bottom end. Would make an interesting combo for a cheap race motor.

That is what I would want to see some numbers on.

Now, you take an LS Engine, any one of them, put it next to a SBF

That’s like trying to put an extra large condom onto your little wiener

Why, why, why would you want to compare a big dollar block splitter that can’t make 500hp before pieces of the block are in the pan with a $300 1000hp capable ‘real’ motor.




…had to sieze the opportunity to make the cracks (sorry..not really haha)

That cam won’t go into a Motown LS. That motor requires a custom cam ….last I checked Erson is the only company that has cores . That was the 3 years ago….maybe something has changed since then.

Talking about the firing order haha the LS is very much based off the SBF. Just better.

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 didn't believe it either until I sat down and actually looked at it. Let me know how that hat tastes.. 😉

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.

That kills the excitement. I thought it was the larger diameter, 52mm???, LS style cam.

LS lobe spacing, takes a SBC timing gear, and has to have an oil pump drive gear. It’s longer than both an LS and SBC cam.
