Ok, going with the Trick FLow heads. Also ordered the Scat forged 4.25 crank and H beams. Using the Crane cams 349551 hydraulic roller.
So what did the bore turn out to be? Stock 428 is 4.135 and you went .030" over, right? That would yield 4.165". Coupled with a 4.25" stroke would put the CID at 463.23. Does this agree with your figures?
Actually I went .025. Had the pistons custom cut, MAHLE forged. Should net me a 461 cid. Will have some pictures of the actual build from the builder someday. Waiting on an e- mail from him.
I love this site, BUT I have on multiple occasions typed this huge story only to loose the content when loading pictures. This is my 4th time and it is unfortunately a rant with no picture or story as I am to fricken pissed to re type it again! Will take a break and try again later.

I've done the same thing.... after a couple of times I began to sit and MAKE SURE I was hitting the right button before I clicked it. Yep, it's a big aggravation!
Eureka, I have pictures! Got the bed on and now I can see all the work involved in mounting the 1974 2WD bed on my 73 Highboy. Had this bed pushed up against the front garage wall for years. It is in great shape. Also found the transfer case brace.
I like your garage art too. Maybe some day we'll have a thread devoted to showing off all the things that we use to beautify our garages, workshops and other working/playing spaces.
I'm curious about your install plan of the ProFlo4... will be installing mine within the next couple of weeks. I'll try to take good notes and pics if you happen to need them.
I feel I definitely under cammed the engine for all the parts I used. Scat forged 4340 standard weight 4.25 stroker crank ( not the 9000 series) using their H beam rods, Mahal custom pistons at .025 over for a compression of 10:6 to 1 and last but not least the Trick Flow aluminum heads in which were port marched to the Edelbrock Pro Flow 4 EFI system. Oh yes and a full Crane hydraulic roller cam with 563 lift @ .050 set up with Harland sharp roller rockers. I can’t wait to light the tires up with this build. Although I had the 428 in there before making 338hp and 430 torque I anticipate this to be a step or two up from there. My intention is an insane amount of torque as low and for as long as I can get it. The truck is a heavy beast unlike a Cougar or Mustang for it to be going in to. I know Hp is part of the equation but a high Hp at an even insane higher RPM will do me no good for my driving and use of the TRUCK. I want that neck snapping torque for light to light so I can surprise all that dare to talk crap on my old heavy Fe powered 4x4 truck!
OMG!! What is wrong with this site? It continuously has a problem uploading pictures. Worst part is I am not smart enough to copy the small books I type before trying to attach pictures and loose it all, lol! Short of it all today is I worked on removing parts from my Highboy bed to put on the 2WD bed I have so I can mount it. Sorry will not let me upload pictures again today!

I have a similar build (Scat 4.25 stroker kit and Edelbrock top end kit) and have similar aspirations. Mine is RWD so a little lighter. We should both see tons of torque. Axle ratios are another key to torque. Mine is a 3.70 which I hope is a good balance between street and other places. Yours?
4.10 but I am not sure if I will run 33” or 35” tire’s.
Yes, tire size is an important data point in calculating the overall effective ratio. Here's a web site that discusses these variables in a pretty straightforward way. You may want to consider 4.56 or 4.88 depending on your intended use.
