    Which would you choose? The GM SP383 long block is $5,700 435hp/445tq and the BluePrint 400 long block Part# BP4002CT1 is 508hp/473tq for $6,100. The best thing about the GM long block would be the warranty but with the Blueprint I could stroke it to a 427 later on down the road. I think i've dropped the idea of going the LS route.

    We all know the specs of the GM SP383 that replaced the ZZ383. So here is the info on the BluePrint 400 http://www.blueprintengines.com/index.php/products/bp-gm-crate-engines-landing/gm-400-main/item/gm-400-base-bp4002ct1

    I wonder who is casting that Blue Print block? That seems the way to go.

    I believe the Blue Print motors come with a 30month or 50000 mile warranty on them.

    But either one of them would be a great motor. My proseries Blue Print 427 is still running like a champ.

    I was going to go with the GM 383 but that was at the time it was being recalled and replaced with that new one....couldn't wait as they said they didn't have an eta on the new motor. So that's why I went with Blue Print but very happy I did.

    Blueprints are dyno tested - meaning the cams are broken in (if need be)

    I would like to have any new engine have the dyno sheet come with it

    The thing that irks me about all GM small block crate motors is that there's not a damned one of them that comes with forged pistons. For a 7-grand list price (6-grand for a long block) I expect forged pistons in case I want to lean on it a little.

    I mean think about that. A $6000 engine with hypereutectic pistons. REALLY, GM??

    THAT is my next engine.

    You're paying for the brand name. All their crates offer less value for the money.

    Holy crap I just now noticed that too! I've been to their site a hundred times and never clicked on this 454 thinking it was a big block.

    That is interesting I did not know Blueprint was manufacturing new 400 blocks with those improved features.
