We have a euro manifold with 40 DCOE's that just came in on a parts car. We just ran the engine to test it out, webers seem fine, set-up is on a 1750, basically same jetting for 2000.
$600.00 manifold and pair of weber carbs, plus shipping,no air cleaners were with it.
We have firewall gas pedal linkage also $60.00
Not sure if you were inquiring about the dellortos when you asked how much.?.?
If so...tell you what...sounds like some good pricing some of these folks are giving you for their kits, so let me clean them up and post some pics for you.
