I'm using a 95 LT1 corvette engine and have the accessory bracket from a 95Impala. I know this sounds strange but this is all going into a 57 Chevy so as you can see from my pictures I have frame and inner fender clearance issues.
My question is; Using the Passenger side accessory bracket, Do I need to use the rear alternator bracket or support brace. Will it be solid enough with accessory bracket and the (for a lack of a better term) two legged brace.
The reason for the passenger side is steering gear box sits high, headers ect on the drivers side.
I don't see your pics but have seen LT1 in a 57. In that car stock F-body manifolds were on (95 camero was donor car) and he had all the brackets. You have headers but you can run at least 1 or 2 of the 3 brackets.
With that said I know other B body 94-96 Impalas running without any of the braces. Obviously GM figured they needed them as they won't spend $.02 more than they have to. Some have noticed belt slip under WOT conditions without the rear brace.
pics of mine
There are 3 braces 2 of which I don't see what they would conflict. The 3rd does go back to #4 cyl manifold bold. Mine came with the headers
Ditto, I distched the 2 braces many moons ago, no slip, no crack, no wobble.
