Sell those 915's to Ademon for $500 since he LOVES them so much and use the money more wisely. What makes you think he needs to do any grinding on the 452's? Remember he's wanting 400hp not 600 and with 3.55 gears and a 2000 stall converter on a 5000# car your thinking way outside the box! 400hp with stock valved 452's is easy with a simple cam swap and headers! 915's don't flow better than 452's and to take advantage of quench with closed chamber heads requires domed pistons milled to spec which A: costs alot of money at shop rates B: puts the compression outside of daily driver/pump gas usage. The speedpro 6pk pistons are good pistons but their too heavy IMHO Just trying to keep it light (old habit) Oh and JohnRR I think his shop is thinking about chevy's with the piston flip.

I think you have that mixed up, you don't need a fancy dome and milling with closed chamber heads for quench, that is with open chamber heads like the 452's. I just did a build with 452's and quench dome Diamond pistons.
Out of the box the 915's probably flow a little better, ported they flow the same as the 452 which is easier for the home porter to do because there is no short turn to worry about which will kill flow if not ported properly.
Every company makes a 2.065ish CH piston which is what the 6pk piston is , mill for zero deck , use a composite gasket and a closed chamber head , DONE. though in this case the KB's might be the better choice with the CANYON they call valve reliefs to keep the compression around 9.5 and very pump gas friendly.
Dust Ya , I figure it was a brand X engine on the piston flip , small block fords can use that the same thing .

I'm not planning on using the 915's mostly because I don't know much about the motor their on and I'm sure they would need rebuilt. I have a set of 452's that have been checked and surfaced they will need better springs but other than that they are ready to go.
The weight of the 73 Roadrunner is 3,525 lbs I don't know if that's with a big block or small block so I would guess at 3,800 lbs to be safe

Smaller camshaft and lose the torker intake.850 holley is a tad big for your setup.Will it work?Yes.Will it be optimal?No.
Cam around 230*(give or take) @ .050.No need for a high lift cam with stock heads.
Run any dual plane intake.Used Performers are cheap and an rpm a little more.
750 Vacuum secondary would be my choice for carb.
Sell or trade your 850 and torker intake for a dual plane and good 750 vacuum carb.Build for TORQUE.Tons of low end and midrange make a mild geared heavy car fun/happy on the street.Short duration and any more than .500 lift is a waste on stock heads.
Exactly! Kinda what I said without the drunken undertones...

Ok so what am I missing here these guys are running pretty much the same parts I already have( low comp 440 torker intake 800 holley) and are saying they run good. Are these guys balancing these motors after they hone and re-ring them or just running them the way they are without a balance? I would love to be able to just hone one of these motors with new rings and have another play toy without spending $2,300 on a motor in a car I'll hardly ever drive.
I better look at this again before I jump and have a motor built.
go for it i had a bone stock 383 with a small 220 @.050 cam with CC 516 heads, stock 68 intake and carb, headers run 12.50's in a RR.

ah yes. again, someone asking for engine build opinions,have lots of mis-matched parts on hand,and hoping to hear what they want to here.... slap one of those engines together (any of them), use the heads (any of them) all the other parts you have on hand already, and it will make 400HP at the tires  ......... that was the answer you were looking for.........
