Approx. Horsepower?
Ok I have 1973 olds 350 with number 5 heads small valves, alum. Performer intake, 1 inch carb spacer, 600cfm holley, headers with xpipe, 480 lift crane cam. Everything is pretty much stock, pistons,etc. Am i anywhere close to 300hp? Thanks

I've got '73 350 .030 over speed pro pistons, balanced, mild engle cam, pocket ported stock heads, performer intake q jet hei, super comp headers, flowmaster 40's
chassis dyno'd twice 220 hp 295 lbs torque at rr wheels -- if that helps ya any- I had no aspirations of going fast with this engine as it was going and is in my '73 Delta... Erik

Probably a bit shy but the torque will be well over 300 ft/lbs if the tune is right on. What is the duration of that cam? I have a similar set up except I have the larger intake valve and the bowls opened up.
