Building a new 505 With Callies / Mopar Performance Block

Nice looking parts. Thanks for buying one of my billet covers. Those have been a popular item for many years.
Compression ratio about 12.5 with those flat top pistons and uncut heads? I'll guess 750 hp at 6800 rpm with a cast intake, but that combo can make more power with some tweaks.
You might end up needing more lift to hit 800 hp, but you'll just have to give it a whirl.
Have you picked out the rocker arms yet? If not, do you have room for 1.70 rockers? You would need to mock things up and check valve to piston. You should be able to get 2.00 installed height with those heads so you should be able to handle 0.800 lift.
I haven't run one of the max wedge Trick Flow intakes yet. I've heard they are pretty good.
That combo will probably work great with a 2 inch header. Something around 2 x 32 with a 4 x 16 collector if that will fit in the car.
Are you going to be able to get it on a dyno before it goes in the car?
