Well, my 440 block is going to clean up at .055 so I am doing the 470 build up. Is anyone familiar with this and how do you like it? Seems like a great way to take many pounds out of the recipricating assembly and get a modern rod in there for cheap. I am using these pistons:

And these rods:

along with a Mahle Plasma Moly ring set. Of course, the rod journals on my stock 440 forged crank have to be turned down to 2.20 size so I can use the BB Chevy rod.

Wish me luck...
 
It can but I am using a 7.1 BBC rod so I can use the RB block. Just wondering if anyone had some input on this. I ordered all the parts last night so I sure hope it works!
 
Yep that works in an RB block.

Those 463-470's make for a good combo.
 
Pluggin in all the numbers to the United Engine deck clearance calculator that piston will sit .117" in the hole at TDC. Sounds like a low compression motor.

I plugged it all into the compression calculator and got 8.077:1 using a 85cc head.
