LS Engines

[Jking24]

I guess it all depends on where and what type of shows your racing at.If you are racing bigger shows on tracks that will have traction early, then it takes so much motor and RPM's now a days that if you build a LS like the stuff we running now it can't be much cheaper once you get to that power level and RPM and make it survive.Why do you think you see so many engine failures lately....9300 RPM with 4" stroke 900HP+ and we could have used more this past weekend.

I don't think most people know what rpm does to help a dirt latemodel through the corner. You can claim all the numbers you want but 9 out of 10 times if your turning 3500 rpm mid corner and im turning 4500+ I'm gonna be better in that corner. And im not talking about spinning tires

You got a lot more engine braking.

They are running LS engines already.......................... Roush Yates Fords!


I had to put that on there for fastford.

haha , i would argue the ls was derived from copying a ford , with the equal spaced ports and all.....

Baldwin race engines has addressed the oiling issues in their LS engines. They are making hi 850-900HP in their LS Late Model stuff. They also do a bunch of Mod stuff and even have a 410 LS Sprint car engine. They have feature wins in all three divisions.

What builder is suggesting to twist your 4” stroke 9300 rpm ???? Parts manufactures probably love that astronomical piston speed ...

Absolutely none of them, but some teams are pushing the limits as now a days you sometimes can use as much as you can get power wise.
