470 going to the dyno - HP/TQ estimates

Your testing will be far more accurate with your carb, your headers and your ignition.

If your headers won’t fit that dyno find another dyno.

Just between those three parts you can easily change your numbers by 30-40 hp

You are correct, but my final set up is Sniper XFlow system and it doesn't make sense to run that on the dyno
