Mostly true.
You can sucessfully run a vac secondary Holley on a light car with good gearing, just put a really light spring in the secondary diaphram and sometimes, open up the orafice that has the check ball (in the diaphram housing) a little bit. You can get those secondaries to open almost immediately, |
