Hello from BluePrint Engines!

It's no problem at all. So LA cores in the quantities we buy, are simply gone from out suppliers. We make a 408, using a 360 block.
That 408 build is going to change to utilize a magnum block shortly, and will have a PN change. Now the only reason that you couldn't use a magnum based block is if you were only purchasing a short block, and were only interested in using a used set of LA heads....now there are ways to use LA heads...but it's not a super simple change. So, not sure where that leaves us .We cant take consumer cores for a few reasons, so unfortunately that's not a possibility.
Let me know what you think, or the reason you have to have LA.
The Magnum block is fine going to use your aluminum heads anyway and not a manic a body man so counting on you to steer me in the right direction.My next question would be will my intake off my 340 fit the Magnum block and all my other parts off it ?
