    Google Blueprint engines. Personally - you can do better from a performance builder close to home. Much of that parts list is the cheapest parts available, and the labor, assembly, and warranty support are lackluster. The power levels are low for the build.

    Overall it would be fine with a 4sp. But you could do much better in terms of parts and execution than Blueprint IMO.

    If you're going to run a HV oil pump, may I suggest an increased capacity oil pan? There's stories of sucking a stock pan dry at rpm and, as you're well aware, that dog won't hunt. Better minds than mine will no doubt chime in on your combo, but at first glance, it seems to be lots of cam for a street car. Not so bad for a stick, but maybe not an auto unless you go with a higher stall converter. Vacumn may be an issue if you're running power brakes, as well. Just my  :2cents:

    Potentially, yes.  However, in the long run you have a high chance of running into big time issues with a cheap build.  If there is one thing I have learned in this hobby, do it once and do it right.

    On the most basic level, unless the seller were a good personal friend, I would never buy a complete motor without taking it apart and double-checking the build before installation.

    If it can do what you want, and if it can do it for a length of time that gives you the return on investment - yes. I don't think it will in either respect. It's a cheap engine, built with cheap parts, and assembled by cheap labor.
    As "they" say:
    Fast
    Cheap
    Reliable
    You can pick any two of the three.

    About a year ago, I put a Blueprint 383 stroker in my corvette. ....
    Ran like a raped ape!  Sold the Stingray to buy my Cuda,  but I thought it was a great engine.

    I'd consider rolling the dice with them again.
