Thanks. I had to learn and re-learn a LOT. I had not touched an FE since 1978.

That thing is happy, what is it landing in?

It is going into a 1966 Cyclone GT 4 speed, assuming I can eventually get the Doug's headers installed. :)

Congrats on getting the engine done.
 At the point you embark on installing the engine/trans/headers I recommend getting a notebook going. Talking about building a cheat sheet for the what goes first, second, etc.
If you have to do it again in the future you will have your own experience memorialized to draw upon.

Are the Doug’s you have individual tubes with slip on collector or a contiguous flange version?

Should I include the swear words in the log? (kidding) A good suggestion, thanks. The right side is one piece. the left side is two piece. 5 and 6 slide on to 7 and 8 (Doug's PN 625S). I'm not sure of the best way to approach the installation. I have a drive on lift but I'm not sure that the ramps won't get in the way. Any suggestions would be appreciated.

Great results!  Would you be willing to share how high you had to spin it to make that power?  (or willing to share a copy of the dyno sheet?)  :)
Thanks and congrats! -Jim
