I do not see anything wrong with it, just needs more attention to certain areas (IMO).
Honestly for seat of the pants feel, and for your combination.....a good torque convertor would do you a lot of good. Pricey, but a great addition to my set-up (love it!!) This is pointless if u r still wanting the five speed, which would also be a good modification if u prefer the stick. If that is the case, GEARS, GEARS, GEARS!!!
Ford heads are restrictive...a good set of heads would be good for you as they would for all of us. What is your exhaust like?

And as a lot of them preach on hear, tunin g ur current combination correctly is always a key, these guys can give lots of tips on that one. The powerband is something I have always listened and felt for. This comes from my dirt bike riding, but has been pretty reliable. How high are you wanting to rev the 289? I would imagine with your set-up, it would be hard to over rev it, I would think the power would die off way berfore then. The valve springs are going to limit you probably first. Any other opinions guys?
