    Just thought I would post an update of what seems to be the never ending project K5. And yes I know I haven't posted since like april. Its almost all skinned and no more rust showing, Still need to do a lot of work, But now im keeping the K5 whens its done due to an improved finacial situation. Anyways, now for the question, I am building up a motor for it, but donno if i should go with a 400 or a 350. The 350 has a lightwieght rods, pistons etc.. and could turn 7,000 all day, the 400 is more of a stocker motor, balanced and blueprinted, but not as built. Either motor is going to have a set of Double Humps on it and probably an edelbrock or similar aluminum manifold.. Suggestions? I will post some pics on the "sliver bullet" in the primer/bondo/multi color stage in a while.

    I think the 400 would be better. everyone has a 350...so everyone has parts, but 400 has more power...

    I'd personally go with the 350 all day long. Shorter stroke, more water jacket volume, stronger webbing between cyl., and it sounds like a lot of the weaker factory parts have already been replaced. Since you said the 400's mostly stock, the 350's probably putting out far better power anyway. $.02 [​IMG]

    Go with the 350, you can buy parts for it at 7-11 or Piggly Wiggly.

    I say 400!!. Build it yourself if you aint happy with its performance, you already got good heads (which usually is the most expensive item by far). Just don´t forget to drill steamholes in the heads if you go with the 400, ok?[​IMG]. Almost everything you can throw at a 350 you can throw at a 400 too!! Btw, did you know GM´s HO 502 big block also has siamese forged cylinders?? Bigger bore & longer stroke equals bigger smile on your face[​IMG]

    Don't forget the old hotrodder's saying:
    "You can't beat cubic inches."
    Also don't forget the classic from Road Warrior:
    "Speed is just a matter of money. How fast do you want to spend?"

    I say it depends on how many RPM's you want the engine to max out at. Because of the poor connecting rod angle of the 400, I would be afraid to build it as a high RPM motor. So here:

    Rockcrawling: 400
    Mudrunning: 350

    Thats what I think.
