Tweet

hello fellas, this is my first posting on this forum. my name is evan, im 21 and i work as a basic mercedes technician... ive worked on lots of modern european cars. but my heart lies with classic american muscle...

i have lots of experience swapping engines and transmissions. i have never built one my own engine i am going to buy a early 80s late 70s cadillac fleetwood... basically a full sized heavy cadillac... i want a small block with tons of torque and hp... i really am dreaming for 550 bhp and 600 ft. lbs. tq.

before i buy the car, i want to have the engine all ready to drop in it. im still young and just need to make sure i get the biggest bang for buck. i dont really know how to fine tune engines for high performance applications. i need you experienced guy's feedback because i am learning..........

i want to buy 383 crate engine long block and install twin turbos on it...
is it possible to put something like this togther for approx. 6,000?
i have no expirence installing turbo chargers or any forced induction system.

this is the engine i was planning on using....

will i be able to get the numbers im hoping for, or close to those numbers?
i notice the motor says 420 hp, will it not be able to handle more?
any advise or comments?
are these turbos good quality or junk?
can i use a carb?
or is fuel injection better?
am i crazy

thanks guys.
