    Hi. I'm just about to install the engine to my 1978 K5. I'm not so sure i know what i wanna put in there. You'd do me a big favour if you answer this question:

    What to you would be the dream engine?

    PS I currently have installed:
    Dana 60 (front)4.56
    14-Bolt (rear) 4.56
    ARB Locker (front, rear)
    39" Boggers

    Drive Safely...stupid hurts

    Fuel Injected 454 - you know the old saying "Too much horsepower is just enough". The rest of the nice things you already have in your truck. What do you have by way of transmission?

    Ahhh, the good ol' dream engine. Here we go:[​IMG]

    Keith Black aluminum small block with splayed 4-bolt mains, bored .030" over, with cooling passages
    K-B forged hypereutectic (sp.?) pistons, 9.5-1 compression
    Manley steel I-beam rods, 6.0"
    Callies forged 383 stroker crank
    Trick Flow twisted wedge heads with stainless valves
    Crane hydraulic roller cam
    AZ Speed & Marine multipoint EFI
    K&N air filter in a cowl induction hood airbox
    ARP 12-point stainless hardware to tie it all together

    As you can see, this is probably close to a $10,000 motor (probably more with the necessary machine work and all the little stuff I didn't list). Will I ever get it? Only if I win the lottery.[​IMG] D@mn, guess I'll have to start buying lottery tickets!

    there is no subsitute for cubic inches the only thing that restricts you is your wallet. i would put in a slightly worked 350 say about 300 hp without external mods such as headers and ignitions. and it shouldnt kill your gas milage.

    I´m satisfied with my 406, even though I haven´t tried it out yet [​IMG]. Just traded a 305 for that 406. Well...if I could have ANY engine I want It´d be a 604cui, brodix or merlin heads...or any other good breather heads....and turbo[​IMG]. Size DOES matter! A well built BIG block is what turns me on. Problem is you have to upgrade the whole driveline to handle the power and torque. I wonder if there´s such a thing as 18 bolt rear ends...and U joints from hell..?...oh I wonder...

    <font color=blue>As others said, it all depends on your budget. What you plan on doing with the truck is also important. If your going to be taking it on tight, twisty trails, a motor with high compresion and an RV type cam is what you want. If your going to be driving through deep mud, better have a built big block. Oh yeah, did you say that you had an ARB front and rear? Do they make one for the 14 bolt yet?</font color=blue>

    I second that. Crate motors are the wave of the future. New parts, already assembled, warranty, etc. I'd get the torquey 502.

    wrt drivelines to handle it, sure. You start getting into the rear axles from 5 ton military trucks, but it's doable. Look at Boyce's stuff.
