Hey everybody. I have been racing dirtbikes for a while and am now going to be building a class 1 buggy to race in the desert. i am going to put in an LS3 motor and build it myself. I dont know much about these motor so i am looking for some help.
I dont want to use just stock parts. I am looking to use different crank, pistons, cams, heads, etc. I am looking to get the most horsepower and torque but also making it dependable and reliable for races like the baja 1000. I am guessing i will need titanium rods and such for the reliability. I will not be using any superchargers or turbos.
Specs on the types of cranks and cams and stuff would be a great help.
For those that dont know much about desert racing like this. Its a little bit of everything. Fast sections, slow sections, lots of off and on gas.
So any help would be great. Thanks...Mike

Definetly going with a dry sump oiling system. It terms of the titanium rods and such, I just want to make sure it is as strong as it could be with the extra power that it is going to be making and for the type of racing and conditions it is going to be put through.

why are they blowing up? Whats wrong with the oil system on the LS3?
Is there any issues with LS7 block in terms of the oiling and them blowing up? If not then...
What is the cost difference between the LS3 and LS7 if you want to build it from scratch? The cost difference in the two blocks is $1300 from texas-speed. But in terms of all the parts, whats the difference in cost? Thanks again for the help.

well with people saying that the system can suck dry that kinda scares me. Its going to be used in the desert and at high speed. The buggy is going to be bouncing around the whole time for hundreds of miles at a time, especially races like the baja 1000, which is like 1,100 miles non stop. No way I want oiling issues. I am pretty sure that I also read that the LS7 got an updated oiling system. So i am trying to see if that one is better.
I understand it will take more money but its for the long term. And if its a better block, then thats what i am going to get. I did some research and a rotating assembly will be about $2,500 and then the heads with valves and springs installed will be about $3,000. Not as much as I would have thought. Thanks again...Mike
