Thanks techinspector1,your input is appreciated.I normally do most of my own work but have become somewhat disabled so I had a speed shop do the work and I went along with his combining of parts...airgap performer intake,670 cfm Holly,hedman headers etc. but what gets me is that my stock 77 460 (other than 650 Holly on stock intake and headers) same gears and tires blows by me at least from light to light.I have a Accel dist.I will be putting in soon and without going "ALL OUT" what do you think as to the torque convertor. I do pull a RV with this truck as I do with my stock 74 f-100 460.
Thanks again,glad I joined....
