    Need Help, I would like to convert my 81 Blazer 383 Carb engine to a TBI. I was thinking that buying a Truck with Fuel injection and tacking off all necessary hardware. However What consist of all necessary hardware and also need to know what to look for. Would a 305 engine with TBI be OK for the 383 Strocker and is the Fuel injector be large enough for the strocker at 425 HP.
    I really need help here, It is save to say that I am lost and do not really now what consist of this swap and is it possible. The 81 Blazer has nothing in sense of Fuel Injection however the Gas Tank does support a Return line. Please Advise..

    Regards Dan
