Default 409hp @ 6k rpm and 427lb ft of torque @ 3500rpm?

I was thinking of tryin to build an engine using these specs,
this is out of Ryans engine combination and bible site.
(Combos 93 to 100)

http://www.ryanscarpage.50megs.com/combos13.html

Displacement: 350 cu. in.

Carburetor: Holley 750 double-pumper

Heads: GM L31 Vortecs, pocket-ported, with 1.94/1.50 in. valves

Intake: Edelbrock Performer RPM Vortec

Camshaft: Comp Cams Xtreme Energy 268 hydraulic, with
0.478/0.480 in. of lift and 224/230° of duration @ 0.050 in. of lift.

Exhaust: Hedman 1 5/8 in. headers

Distributor: HEI

Comp. Ratio: 9.4:1

MAX HP: 409 @ 6000
MAX Torque: 427 @ 3500

The vette I have is a 78 with a 3.08 rear and freshly rebuilt TH350 with original stall torque converter.

My question is, how would an engine act that reaches its peak torque way before max HP is reached. I chose it cause it looks cheap to build "non roller cam". What would be a good stall speed and rear end gear. Thanks

24-2600 stall

3.50-3.70 gear
700r would be really fun with the lower first gear, would pull OD just fine on the hwy

Wouldnt sweat where torque/hp peaks are on this one
With an AFR 180 head that combo would really tear it up on the street!!
