George;

You have to agree that a '69 two door with a B20B is a pretty desirable Amazon to get if its (sheetmetal is) in decent shape to start. Its almost a 123GT, which is THE most desireable model!

TomTom:

I believe you will have a cast dual throttle, 2 into 1 (mixing chamber), back into 2, then 4 ports, intake system (one piece casting with exhaust) which is tough to get to idle and should probably be replaced by an alu. pre '66 intake manifold and (cast) 4 into 2 into 1 (pipe) exhaust maifold. I agree with George, significant gains can be had by improving the engine breathing...

Sound proofing...stick-on mats available from automotive sound system places (ie www.partsexpress.com) go a long way, but I swear on of these days I'm going to come up with an underhood sound deadening foil/foam kit (ala 1800s) to attenuate engine noise coming from that big hood.

The dual brake system is definately nice, and the benefit of changing to disc rears vs. the amount of work involved is arguable.
