Hi Trendz,

The car will have dual quads, so yes, I would want progressive linkage. It is a 604 Hemi that will be street driven, but not a cruiser, only a blast around town with a trip to the track once or twice a year.

The Black 112-602 race has the "Dedicated race only throttle lever" and from the pictures, the throttle lever is much different than the 112-587 universal throttle body, and the latter looks to have more sensor inputs???

I did talk with Holley today (finally called back) and they told me to buy the Holly EFI Digital dash (553-106) that replaces the 5.7" (553-103), but like Monte and Mike said, I will really need a PC laptop for the initial program load.

All this EFI stuff is new to me, so there is quite a learning curve.

BR, Mark
