Well written....

Two words: Oil Pan.

 

It would take a ridiculous sum of money to get an LT based engine into a space designed for an LS engine. Most likely your front end would be overloaded by the time you were done. A 5.7L is a heavy engine, go for a 5.3, or 6.2L both much lighter.

 

Ok 5.3 or 6.2 got it thxx if before i start found it will cost more than i expected ill go for rear diff lock and infront ill put ARB lock and some hp tuning with 35 wheels
by the way how can i lift my h3 i couldnt find any lift kit except the shakles and torsion bar the h3 is not like the wrangler where u can load alot od mods in it

 

You are wandering off topic. Short answer.... there are no lift kits currently made for the H3/H3T. Feel free to search here and post a new thread in the H3 section if you can't find the answers you need. Please do not dig up old threads by tacking on the end. Frowned upon here.

H3s are not Wranglers. All an H3 needs is tires, UPC, Rock Rails and a T Bar adjustment to bring the front up to 23.5" fender lip to hub center. You do NOT need to buy any "leveling kit", the stock T bars can get you all the 3 can handle. With the above, and a bit of H3 driver experience, the H3 can wheel the bajezzus out of damn near everything.

Like the Rabbit says: lift kits are for kids.

 

Hey, what about break over angles DOC!
