Holley Throttle Body

[WildThingAndrew]

I was just wondering if anyone has replace their stock throttle body with a Holley Throttle body ( 670 cfm ) and was it worth the money?

It is questionable what you would gain without doing a few internal engine mods as well.

I've not installed one myself but I've heard that the injectors that come with the holley tbi are garbage. In order to see any gains from that you'd need to upgrade your intake manifold and have the bores on the manifold bored out to 2" each to match the 2" bores on the throttle body. Replacing the tbi heads will also make a mod like that more worthwhile.
