1966 289, C4, 2.80 rear end. The engine is a stock '66 block. Seven bores are within .003 of new, but one is worn about .006 or so with .004 taper. I don't think a simple hone & re-ring is a good idea, but feel free to disagree if you want (it would save me close to $500 in machine work and pistons). If I have to pay the $300 or so to bore & hone, I'll just go .030 over.
Flat top pistons (or? The originals are slightly dished...)
Either stock GT40P heads - close to 9:1 or 9.5:1 compression
Stock cast iron exhaust manifolds
Either stock 4V or maybe something like an Edelbrock Performer street intake (not selected yet)
4V carb (likely a 4100), not selected yet
I could re-use the original heads, but I have read that the GT40P heads would breathe better. It would probably be as expensive to use the old heads as to replace them, since the tops of the valves are grooved and worn from the rockers.
Not looking to spend a fortune on machining them.
Nothing wild. Not a race car. With those gears I'm looking for good low and midrange torque. It doesn't need a silky smooth idle, I want it to sound good but not lope and spew half-burned gas. There are thousands of cams out there, and I'm not an expert. What say ye, assembled experts?
