How Much Horse Power

73 Mustang Boy · 08-29-2001, 08:11 PM

I have a 73 mustang that I swaped a 351W that I built into and I would like to know some realistic HP estimates. It has about a 9 to 1 compression ratio with GT-40p heads. A .488 lift cam with I think a 218/210 duration. Weiand Stealth intake manifold with a 600cfm Edlebrock carb. Shortie headers, 2 1/2inch exhaust and 2 chamber flowmasters. I realy dont care too much about the HP because I love to drive it, and do drive it every day. Thanks for any help you can give me.

Make a couple 1/4 mile runs and get an estimate that way.

I cant realy make a 1/4 mile run because all the tracks I know of are only 1/8 mile tracks. My 1/4 mile time will be slow anyway because I have 300 gears in the rear end since I drive the car 200 miles home from college alot, not to mention that muy friends and I constantly drive the car 70 miles to savanah.
