I remember these on the SHM website back in the day. I can’t remember if they were mentioned in the modular book that SH wrote. If I remember correctly these cost $4,500-5,000 new, plus
shipping from Canada. The casting quality appears to be very nice! This is a great deal for someone!

yes 4.6 deck. 3.750 stroke 3.700 bore 5.850 rod should be 5.4 or more.
only reason I am selling is 3 bolt mount my fr500c uses 4 bolt.

I’m in Orlando, but could travel to the east or west to link up closer to a major highway heading south.

I’m debating on this one as I’d like to use my 2v heads, but the compression would be 12:1. Investigating a 4v swap now.

Not sure what the correct repair is for the crank. That’s a tough one

So what heads work with this? Not sure what you mean with the 3 vs 4 bolt fr500c, isn't that head the same bolt pattern as any other modular head?

early 4.6 blocks us 3 bolt motor mount.later blocks had 4 bolt mount.
all 4.6 5.4 heads use same bolt pattern you can use 4v 3v or 2v heads on it.

I am no fan of Sean hyland but the casting in this block makes all ford castings look like crap.

Sorry, I forgot to respond to this.

I am still trying to figure out what I can do with this since the c/r is higher than I was originally planning. Regarding getting it here, I would probably ship it as me getting away from family during thanksgiving time is probably not going to happen.
