Have you thought of using a shorter rod length with the longer stroke to use those pistons?
I have made the mistake of buying a part and then building a motor around that part That is not the smartest way to start on a new motor build unless your absolutely sure you want to build that new motor that way

I have thought about it, but don't know how good that would be.

I had a 4.150 crank in mine. I started out just adding some alum edelbrock heads. After getting them back from modern I also decided to step up to a 4.5 crank. I'd like to drag the rpm range down a bit and pull some gear out. It'll still be a street motor.

So Hudson, what is the compression height of your pistons? How about pin size?

Here is a pic. Haven't bought them yet.

At first glance it appears you could use them with a 4.400 stroke and 6.76 rods.
that's the aftermarket stock length for B/RB crank
10.725 - 1.765 - 6.760 -2.20 = 0

Or easy as pie 4.5" stroker with 6.700 inch rod, piston a little below deck.
Easy as ordering the crank and rods.

So while I was originally going to say don't do it, it appears it may really be a good deal. 528 cubic inches with Hemi heads sitting on top should equal huge power and torque.
