Going to Build 470 Street/Strip Engine for 71 Demon

Hey, Greetings from Finland!
Im going to Build 470 for my 71 Demon Street & Strip car. My current plans for engine is:

-77 Year 400 block bored to 4.375 and decked to 9.975 deck height. Aluminium main caps.
-Molnar 3.900 stroker Crank.
-Molnar 6.700 BBC rods.
-Diamond Pistons 1.32 CH with -12cc Dish.
-Trickflow 240 heads with 1.6 Harland Sharp Roller Rockers.
-Weiand tunnel ram intake.
-Mechanical Roller cam?

Does this setup sound good for you?
Update on my last post.
I run the same stuff. Milled my 240s to 65 cc
Welded and ported my tunnel ram.
Solid flat tappet 264-268 .
Made peak power @ 5800
Had over 600 ft lbs down a 2900 rpm.
My combo made 685 hp and 665 tq.
I am going to port my heads out to the bigger Hughes gasket 2.625 height port vs the 2.375.
Also am buying parts to use a mechanical roller 272-284 .700 lift.
That's going to be a good combo.
