408 build. Numbers are finally in! For those of you who have followed previous threads of mine I was always worried about what the motor would make. Yesterday it had a few pulls on the dyno. Motor made 619HP and 580TQ at the flywheel. Motor was still being broken in and he didn't make a max effort pull. My setup is as follows.
11:0:1 compression
Dart 225 cnc heads
Intake and fuel system is all holley
60# injectors
1-7/8 headers
237/242 60*/60* 113LSA
JE pistons
Forged lower end
I feel these are solid numbers. What are some of your opinions ln it? Right where it should be or should i have expected more?

Thanks guys! I would love to be ~500 rwhp. The builder figured I'd be around 420 rwhp because at this moment I only have 2.5" true duals and it's going thru a th350 with 3600 stall and 8.5" 10 bolt with 3.73s. Once the motor is in I'll have the rw numbers. Goal is 10s. Car is am 86 cutlass 442.

Im not really sure. All I know is that they were cnc ported? I also misinterpreted what he was saying for the power it made. It made 608hp 575tq he said once the the rings and everything seal from driving it it should pick up another 20HP.
