I will be building a 289 for my 65 coupe soon, and wanted to get everyones recomendations. I have been leaning towards a fordged and very well balenced bottom end. Trickflow heads and a weiland single plane intake. Then possibly adding a blower down the road. Staying with the high reving 289 what would everyone recomend? Thanks,
John

Plan your time and map out a budget. Then double each.
I like your idea of aluminum heads, although I'd probably go with Edelbrock or AFR165 or AFR185s (probably overkill with your "small" displacement). Nothing wrong with the Twisted Wedge heads if you get a good deal, but you got to watch valve clearances, particularly with a hotter cam/advance/lift you need to make power out of your 289. You will have some more clearance issues with the "big" valves (Edelbrock's 2.02 intake valves, for example, and others), especially if you go roller.
There's no substitute for balancing your rotating assembly (harmonic balancer, crank, rods/pistons, and flexplate or flywheel if you plan on revving it and keep your engine happy. You might also consider the roller conversions to free up some more power.
Power is expensive, so plan accordingly and budget. 
There will be many more suggestions, and I'm sure some will disagree with me.  Good luck in whatever you choose, and have fun. That's what this hobby is all about.

Not to disagree, but power isn't near as expensive as strength. You could build a 400 hp 289 for a few hundred bucks, but it wouldn't live through one dyno pull  One thing to keep in mind with aftermarket heads and a short stroke is c/r. Early 289 heads have tight chambers to get 10-10.5:1. 60~ish cc chamber volume is the norm on the aftermarket stuff, so you could be into domed pistons to get some compression. Trick Flow heads have awesome power potential but require alot of changes as the valvetrain geometry is TF and not FoMoCo. 'Standard' domed pistons will not fit without machining, but TF-specific domed pistons are available. Unfortunately, they're real proud of them  As shallow a torque curve as 289 cubic inches will make, I'd favor a dual plane manifold over a single unless its a competition-only deal, as the street driveability will be much more tolerable  ------------------

What piston / compression ratio would be recomended and still be able to add a small blower down the road. But not be under powered without the blower?Thanks,
John
