I want to build a budget 451 stroker.... school me.

You might look at doing a 472, I've always heard they perform better than they should and it's almost the same build as the 451. Mike, Hemirunner what do you think?
Of course you could just build the 400 with a really good set of heads (Trick flow 240s) and get the same performance as the 451.
Several ways to get the same result. Just depends on what you want.
 
I did a 400 to 470, damn thing was an animal! Tires stood zero chance of survival launching at anything above 1500 rpm’s.

That’ll add some cost as you’ll have to offset grind for the additional stroke and in doing so, you have to go to the 2.200 journal requiring aftermarket rods. If cost control is a factor, the 451 is probably the best bang for the buck.
 
So what exactly was the cost of buying the crank, the crank grinding and counter weight cutting, rebuilding the rods, file fit rings, pistons, rod bearings, main bearings, and balancing the assy, and when did you do it? Lets be sure we're looking at his cost in today's dollars.

Exactly what rod did you use with that 1.908" compression height KB240 piston?
As I mentioned I already had the crankshaft and cut the counterweights myself (literally a 20 minute job), I made sure I stated that to be accurate for the OP as well. I did my own rings as anyone with a set of feeler gauges can do along with all of the assembly. When.. maybe 5-6 years ago, I'd have to look? Pistons were installed on factory 440 rods (I'll confirm the 240 part but that rings a bell), they were at zero deck height after having the deck milled/ground. This was all done recently enough that there should be little to no cost difference in parts or labor. As far as listing every single cost... I'm not digging out papers unless the OP has a specific question. I will say I ordered almost none of the internal parts, I just have the machine shop order most of the internals as they determine the needed under or over size but it's all good stuff.
