Thanks in advance.
I have a 408 sbc that I believe has more potential, but I'm at a loss. I was hoping for 600+hp. Maybe that's unreasonable. Here's what I've got.
2 bolt block filled to bottom of water pump holes, fitted with splayed 4 bolt mains
.040 SRP 4cc dome pistons, H beam 6in rods, internal balance steel crank.
Howards solid roller: in. 269 @ .050 ex. 277 @ .050 .675/.650 lift respectively
AFR 210 cnc ported cylinder heads, 2.08 in. 1.60 ex.
Edelbrock super Victor intake
Holley 950HP carb
Hedman 1 7/8 open headers
Putting it on the dyno would be nice,

These guys here know a ton more about drag racing combinations than I so I'd listen to them.
