There is certainly nothing wrong with a GOOD, properly built 428.
BUT, the question is: Are the parts you've mentioned all usable for a correct 428 build ?
(1) Are the pistons in good re-usable condition ?
(2) Will these pistons work in the block, or will the block need to be bored bigger, & larger pistons bought ?
(3) Is the crank in good condition and can it still be cleaned up at a size for which rod & main bearings are available.
(4) Are the cylinder walls thick enuff ? A good machine shop can check this, as well as check the block & crank for size & cracks.
A good 428 will have much more torque/hp than what you said you wanted.
If you go with the 428, I'd go with forged H-beam rods. RPM brand H-beams are $400. Eagle H-beams are about $475. Some say that the cast rods can be resized, using new ARP bolts for about $200 or a little more. BUT, you still have CAST rods that are over 40 years old. I think the extra $200 for H-beams is a very good $200 investment. Why put cast rods in an engine you'll spend thousands on, when for $200 more you could have much stronger & lighter H-beams ? Hey, that's just my opinion. There are lots of cast rods still in use every day. But, lots of engines have been destroyed by broken cast rods.
