Default Re: Ford Engine HELP ???

Found one of the time slips, 1.68@60', 7.75 - 89.56 mph @ 1/8, and 11.98@119.29 1/4

The car did leave kinda soft, I figured I still ad some adjusting to do there.

It didnt feel like it spun the tires, I was thinking the 3.73 gear may be off, might need a 4.30, or so, shifted at 5800, and went thru the top end at 5750. Friend of mine told me I did not want to twist a Hydrolic Roller motor past 6400.

I found the cam specs as well here they are.
