I am going to start working on a 427 small block for next summer. I'm wanting ot know who and where I can get the stuff to make one. I know its a 4.1 bore and 4in stroke. the only people/places i can find them is bill mitchell(sp?) hardcore racing. i would like to build one myself anybody know of any places that make the parts?


thanks

A 427 small block is usually a 4.125" bore (std bore 400 block) with a 4" stroke crank. You can get cranks from a bunch of places; Eagle, Callies, etc. Odds are you won't be building a 427, if you use a stock block; it'll probably end up a 434 which is 4.155" bore.

You're going to have several thousand dollars tied up in a short block by the time you're done with this. There will be a bunch of assembly and disassembly, repeatedly, and lots of grinding. If you're going to build it yourself, you need to do some research, get the details right. Otherwise you'll end up with one veryexpensive boat anchor.

 

A better choice for the block might be World's Motown block. Available with 4.125" bore, either 350 or 400 mains, no clearancing needed for 4.00" stroke.

It'll run $2000-$2400, but it's a better block than factory, less machine work to do, etc.
