small block 671 blower ?

This engine is being built as a race only endeavor. In the future I may convert it to street after I meet my max age for racing(agreed with family).

Altho all parts have not been procured I know exactly what it will be:

X block w/413ci
4.10 bore
3.91 stroke (offset ground 3.79)
Lentz 6.2 rods
Racetec pistons with approx 12cc dish (11:1 CR)
E85 fuel
Flat tappet cam 265/275 @ .050, .585 lift, 115LSA
LP Commando heads w/2.02 & 1.60, ported by me.
Harland Sharp or Norris roller rockers
.100 Cometic gaskets
6-71 fully stripped blower
Hilborn Bugcatcher Hat

The philosophy behind this configuration is that if I don't like the blower I can easily change configuration to run carbs at a higher compression ratio by changing head gaskets and cam.

Sounds like a real nice engine. What are you expecting for times? I would guess 8's.
