It "feels like 400+" because these engines have a nice, broad power range.

Flat top pistons or rebuilder dished pistons?

Stock valve sizes and no cylinder head porting?

Headers?

Assuming dished pistons (9.5:1), no porting, optimized jetting and timing, I say about 370 bhp. Add flat top pistons & porting, 400+ is realistic with a good tune. Also, ported heads can offer up a lot more power with a bigger camshaft and Holley 850 carburetor.

Nice build, you're going to be pleasantly suprised at the fuel economy your combo is capable of provided you drive the vehicle like point-a-to-b transportaion.
