Anyone Here Ever Dyno Their Mild Built Small Block Car?

I remember on my 68 barracuda the 318 had enough to bark the tires as it shifted to second and it was bone stock...though the tires were pretty narrow. Still you will get loss. However don't forget you multiple your power so even modest gains can do a lot. Just remember all the big HP numbers new car manufacturers use is at the crank so it sounds like you are doing pretty good in my opinion.
