That's a good observation on your part, the brackets are the exact same ones used in the Holley LS FEAD drive set-up, which are adapted to the bolt pattern of the LT engine by means of the adapters in-between them both. This configuration was beneficial in keeping cost in check so that pricing will close to what the LS set-up is. The alternator position won't be preferable by everyone, especially those using a stock take-out ECU and wiring harness. For those going with an aftermarket EFI system like those from Holley, then the connections needed are just as easily made as if the alternator was mounted elsewhere. I know our beloved GM trucks are the focus of this forum, but there are many more applications Holley makes swap parts for that require configurations or designs that are not necessarily optimized for our trucks.

Of course, I'm a master tech for BMW and one thing I know is you can't please everyone.. but appreciate the support holley is offering though

Does the holley brackets fit a stock lt1 alternator?

This is basically what it is.. it woukd use the captors alternator and tensioner... gonna need to put the intake on it, but it should be 0 problems with that, and ad far as hood clearance, it's only raised maybe 1-2 inches... if the intake is higher than the alt, no problems

I'll have to find out for you as I'm merely the information middle man on these components.

Minor parts
Oil cooler bypass cover just incase the oil cooler manifold doesn't fit.

And the long awaited fuel pump driver module connector.. brought 2nd one to use for one additional harness



Besides the belt drive that's almost worked out and motor mount adapters I think I'll be ready for the swap.

87Chevy.com, the Holley alternator bracket will accept the LV3/L83/L83 truck alternator, but not the LT1/LT4 alternator. This is due to the mounting hole spacing difference between them.

Cool, thanks for the details.
