Dog, Yeah I remember Arias would make you a 451 slug, with a .990 pin and you had to bronze bush your LY (or my prefered 383) rods. The undersize of the slug had "427" (chevy BB) cast into it. You're right Arias and Venolia were about the only 2 Piston players that would make you one back then. It was expensive but fun times, very 'hush-hush' back then in the pre F.A.S.T. days when we had a few very quick '383's trawling around

Everyone ( the customer ) has different needs,wants,expectations and especially budgets . I would love to sell every single customer a new crankshaft,rods and pistons. That would be a perfect World indeed. The reality is that simply isnt going to happen. When you build enough engines as a business, and not a hobby, you find out you deal with an incredible cross section of " personalities". They have many many different requirements. This is where a builder needs to put himself in the customers shoes as if it was their money and build. I agree that its always best to use new parts whenever possible. I recently did a 451 with stock crank and stock 400 rods. There was no need for this guy to buy a new aftermarket crank and h beam rods. He took that money and put it into a set of Edelbrock heads. He wanted a torquey,simple drive it anywhere street car. Thats what he got. The original poster asked some specific questions obviously so he knew more about how to make 451. Does he need a new crank? I dont know. None of us know his budget or needs at this point. Good info here, but be careful of simply broadbrushing everyone into the same picture. Bobby, i do agree on the 4.250 crank motors much of the time. Usually just makes sense, but again, not everyone wants or needs maximum torque and horsepower. What did thoseu 431's go in amd how did they run? What heads and cams? I like the availability of the 383 blocks for the street/strip guys.

All the work is in the crankshaft.
Mine makes 525hp 500tq at the rear wheels and is street driven on a regular basis.

With typical 6.76" long connecting rods, a piston with a compression height about 1.32" puts the piston near zero deck. Some specific rod lengths, pistons, and block deck heights may result in the piston down the hole (low compression ratio); so check the details (especially the machined deck block height) of the parts you plan to use:
+9.980 Block deck height (could be 9.97x after machining) -1.875 Crank stroke divided by 2 (3.75/2) -6.768 Connecting rod length (many H-beams are 6.760") -1.320 Piston compression height ------ 0.017" below the deck
And be sure the pistons you buy use the pin diameter to match the connecting rods you use (1.094", 0.990" common)
Examples of pistons: Bore___CH__weight_ring pack sizes__piston pin size_ part no. 4.375, 1.320, 510g, 1/16, 1/16, 3/16, 1.094 x 2.930, 99494 Ross 4.375, 1.320, 527g, 1/16, 1/16, 3/16, 0.990 x 2.930, 99495 Ross 4.375, 1.313, 524g, 1/16, 1/16, 3/16, 1.094 x 2.930,131175 JE 4.375, 1.313, 525g, 1/16, 1/16, 3/16, 0.990 x 2.930,131174 JE 4.375, 1.300, 515g, 1/16, 1/16, 3/16, 0.990 x 2.930,K296A35 Wiseco
Check KB also. I don't know if all the above are still available, but they were stocking parts back then.
