I tried calling Holley, but they don't seem to have application support...
I may get rid of my tax return with a Holley Pro-Ject system for my Hornet. (No LP conversion at this time; I want on-road fast!)
Holley makes one kit, 501-12, that is a 300cfm bolt-on for the Jeep 258. This sounds like the correct kit for me. However at least one person is saying I should get the 670 CFM kit instead. There's no real difference in price, and both are 2-bbl replacements.
Does this sound right? Are holley CFM ratings conservative or bragging?
