Hi guys, I'm new here, but have been building engines for 38 years, mostly the small block "C" brand.
I have a question for you FE experts. I have access to a half dozen FE blocks as I write this, and want to know which would be the best block to choose. They are all 390 blocks, as far as I know. I haven't put a mic to any of 'em yet.
First off, out of the six blocks to choose from, there are only 3 different ones of note. One of 'em is one with the mains that have the little nubbies on them where a guy could convert it to a 4 bolt cross bolt set up.
The second one is a block that has these verticle lines cast into the bottom part of the outside of the block. And, some have told me these particular blocks can be bored out farther than the others.
The third style is just a standard FE block with no odd identifiers.
Thanks for the help, and if ya need more specific info, just say so and I'll go find it.
