427 FE Block Question

[Richard Cowart]

This all sounds like a block that has an imperfection in one of the casting numbers. The block is good, it just cannot go into a Ford car at the assembly line. But, the block is perfectly good so off to an auto parts house, engine builder, etc. Thanks to all.

Even though they were NOS blocks, many were rough and needed cleaning up and even some machining to correct bores, bearing alignment etc. I'm hoping your builder knew about this and completely checked it out before the build.

Yep, I know it's hard to believe, but there was very little rhyme or reason to casting numbers because there were exceptions to every rule. You simply can not make a blanket statement about casting numbers other than that you can not rely on casting numbers. But if it's an unmolested 427 block, even in "rough" form, it's a very nice find.

It was described to me as brand new, sitting in the shop for a very long time.

My understanding is that he is very reputable and one of the best. They put all of the right parts in the engine. Dynos at 585 hp and around 591 ft lb. torque. Comes with a 2 year warrantee.

If it doesn't come apart in the first six months then it will likely outlive both you and your heirs.
