LS motors used in dirt track

[sprayedenali]

maybe it would work in modified racing, but in any of the stuff im around a LSx couldnt quite keep up. most dirt late model motors make 850+ and i havent seen to many ls motors make that without some sort of power adder.

Thats was freaking hilarious! Its funny how one quote he used actually killed his argument. Where it starts "the engine blocks were cast in aluminum for car applications, and iron for most truck applications"

What a tool. You just fail at life when your own research proves you wrong.

But I'm glad to know I've got a aluminum block

actually that was the reasoning that was floating around years ago. they said the AL block wouldnt be teh best for a work truck. since a truck is truely intended to be a work vehicle they went with proven iron block. for heat issues and ridigity

Just a quick check and that seems like they are getting away from that now. Would that be right, meaning gen IV? I still like the thought of having a iron block, the lsx branded are iron (new 454, 427, and 400) to be able to push the 2500 they say they can handle. And thats why they say they used iron, and like you said for heat and rigidity, and its proven.

just to be sure.. I know my block is iron.

only advantage i see the aluminum has over iron is weight of a vehicle. great for street rods and etc. I like knowing i have a iron motor in my truck. iron can take alot more heat without much distortion. look at diesels

for pussy trucks that dont do anything AL is fine IMHO, kinda why toyota uses them. Fake ass women trucks

yeah the late models here are either running sb2 or 14 and 18 degree headed motors. But for a modified or street stock type car it would work great.

those guys were getting seriuos. If I heard that one dude right, did he say that ALL gen III motors are AL? Doesnt it make you want to create an account on there..lol
