hey you guys, does anyone have a vacuum hose schematic for a 350ci in a 1970 chevelle? some of the hoses that i have connected may not be correct. or maybe you can tell me where the distributor vacuum goes to. and the transmition modulator valve vacuum hose where does it connect to on the engine? thanks in advance... charlie

May try the engine forum if no one shows up with an answer here.

This is how I did mine.
1 - PCV to large manifold vacuum port on carb.
2 - Trans and A/C control to small manifold vacuum port on carb. (installed a "T")
3 - Manifold vacuum port on intake to booster.
4 - Ported vacuum port on carb to HEI.
Good Luck graemlins/beers.gif
