We run a home made turbo set up on a LA/Magnum hybrid. Makes close to 850Hp. But it took a lot of fab work. Also has good pistons. Our 1st set up was truck manifold turned around backward, home ported iron heads, good pistons, reground factory cam, good valve springs push rods and rockers, blow thru carb on E85. With a trans brake and 2.76 gear it went 10.99. With converter upgrades 9.99 with a 3.23. With bigger cam, better pistons designed for boost, good rods, ported Eddy heads, 3.55 Dana (8 3/4 no longer survived). Its been [email protected]

3885lbs. Making 450-500hp is easy without a power adder. More than that not impossible but not street friendly or cheap.
