Boned up on a car purchase, need a 428/455

Finally got the car and decoded the engine... not great. It's a 1976 Pontiac 400 with about 7.5:1 compression. At least the 6X-8 heads are decent, though they have huge chambers.

So odds are this car was born with a 428/360 but it went away at some point in it's life.

My plan is to fix all the little things wrong with the car (heater blower, a few power windows, that sort of thing), then decide on the motor. But I'll get everything else working properly first!
