I was wondering if anyone has run Holley's 670 cfm TBI on their car? Is there any difference in performance? Also do you think it was worth it? I have herd it is alittle big for a 305, but I have a few things done to mine, so I think it may work. It would be going on a 91 camaro rs 5 speed.

 

it is a very nice peice. i don't think it will be too big for you. if you have done any head/cam work on a TBI car, it is a needed upgrade. the biggest thing with the holley unit, is getting the fueling right, if you have many mods it may be better to go with the 350ci unit, as it has larger injectors.
