Just curious if anyone that has installed the 290 Hp crate motor from GM has encountered any low vacuum problems? Used an Edelbrock Performer intake and carb and can only get 12-13 in of vacuum. Thanks

You may want to check for a vacum leak, have had one in my 45 for 6+ years with no vacum problems using an offenhauser Z-28 style crossram intake and Holley carb.
