We are having a debate here at the office

How much power would it take to get a SBC to run Mid 8's @ 2800lbs?

Assuming the chassis is setup properly.

I am thinking it's going to need to north of 900hp to pull it off, my boss thinks it can be done with about 850

It all depends on the chassis and RPM.
if you spin the thing to the moon, you could get away with less power.
I know of a Super Stock guy making around 780hp with 316 inch engine and they have run 8.60's @ 3000lbs with a back half car, but they leave the line at 7800 and shift at 9800 and go out the back door around 10,200 Torque Flight trans, 7 in converter, 6.00 plus gearing with a 14x33tire

Thats some insane RPM.... But good thing to go off.

so then a well built 427/434 should be able to pull it off with 950hp and 9000rpm assuming everything works together.

I think so.. Although I would rather see a 3.80 stroke and 4.155 bore combo, than a 4.125stroke and 4.125bore.
