68 427 block for sale, ready to assemble

The Marketplace Miscellaneous Parts for Sale

New to the forum, likely know a lot of members, been an FE guy on all the forums for a long while.

I recently came into a 7F dated 68 hyd cammed 427 block, .040 over, that is ready for assembly. The original owner of the engine got way upside down with another builder and then didn’t trust the assembly. I took it in and after finding issues with the heads, intake, rockers, and a long list of mismatched bolt ons, instead of finishing the engine after I did all the blueprinting for it, he washed his hands of it. It had an old school rotating assembly that I sold (SCJ rods, CJ crank, and a set of Venolia pop-ups) but I was finished with the short block measurements and balancing and was ready for final assembly when he decided he was done.

Little to no measurable taper, clean and nice, sonic checked good, a couple of cylinders have a light skirt scuff due to the last builder not beveling the bottom of the bores. My recommendation would be to buy pistons to match the bore and assemble as either a stroker or a stock rotating assembly.

Here is a link to all of the pictures so you can look at all the cylinders (I didn’t want to go crazy on linking pics and make it slow to load)

And here are some key initial pictures, note cross bolts and spacers are there, I just have them off to the side while I was documenting the build. Has new ARP bolts and was align honed.

Happy to get any other information you want, as I said, this was going to be a build and I have all the information available… Looking for 3500 plus shipping from Omaha, bare block only, First picture was as it came in for blueprinting, the rest I took for someone else interested. Numbers on the bottom are current bore sizes

Ross?

This looks like a pretty good find if it’s legit.

Yep. it’s me! I don’t recognize your sign on name here.

It’s legit, just trying to get back some of the money lost when the owner backed out. I was considering using it for my next build on my own, but it’s going to be a superchargered EFI stroker, figured likely best to go BBM.

Mark aka FirstEliminator. .040 over is o-k on a 427?

Ahhh, I figured it was Mark after I did a search and saw a couple of Massachusetts references.

.040 over is doable on most 427s, but you don’t have a lot left over, heck no different with 428s and 390s with the core shift I have seen. I turn away more 428 industrial motors that are thin at standard than I use

However, you sonic check and if it’s good, it’s good. This one did, and it’s not like it need to go .045, the bore has no taper. My 0wn 427, 489 inch EFI, alum heads in my Mustang is .047 over and has been together since 2006. They are all different, but .040-.045, usually good, but like I did with this one, you need to sonic check

I just advertised this on Facebook, dropped it to 3000, if anyone is interested.

Funny how many people want to send me a 10K check and I just refund them 5K and the block…Facebook is awesome for deals!

Sold, thanks for the interest. I almost backed out on this sale, it was a nice one. However, a BBM order is going in for my own supercharged build, hoping for 4 digit HP, EFI, street machine! Really wanted Twin Turbo FE, but just no real estate under the hood
