Throttle Bodies

[bruce plecan]

For butterflies, use Barry Grant, 1450 Mc Donald Rd. Dahlonega, GA.,
(706) 864-8544.  As I recall was about $10, for a pair of 2" ones, for
use in a cross-fire, had the throttle bodies machined for a 2" bore, and
it went really slick.  IF YOUR remachining a GM TB, tell the machinist
to cut really really slow.  It's a "funny" al. alloy.
