Any of our pros hear of a new Speedmaster 427 block that is almost a dead ringer for a BBM? Pictures got posted on FB earlier today and are now gone, but supposedly the price is $2400. Didn’t see the Speedmaster that was supposedly cast on the block but there were visual differences from BBM… is a $1600 discount worth the risk of a Speedmaster block?
No, it's not.
I would consider the BBM block to be one of the pinnacles of aftermarket FE blocks.
I would consider Speedmaster to be one of the lowest quality brands in all of aftermarket engine parts. Not only does the quality stink, but the morals/ethics also stink. They have made a living of copying good, high-quality, name-brand stuff, such as CHI, MSD, Comp Cams, Edelbrock, etc.
