Thanks guys for your thoughts. Maybe I am getting ahead of myself to think 500rwhp is achievable with this set up. I thought the new pipes/headers would bring back some of the low end torque I lost due to the 950cfm carb. I was talked into the carb by local race shop paid 1000 dollars. Performs much smoother than the 770 street avenger it came with however, not as snappy. Should have done 750 or 850 cfm carb instead. My thoughts were, if I could get the air out quicker I could let more air in. Roush says 427srtw should be 535hp and 535tq with vic jr. and 770 carb. Thank for the advice.
