Looking to put car lsa in my 69 Z and was wondering will the low mount accessory drive fit? Have speed tech pro touring subframe?

 

A lot will depend on the motor mounts and steering box used. How low and forward or rear the motor sits makes a difference. GM performance Parts, Holley and others have kits that give dimensions that may help determine what will fit.

 

I am switching to rack and pinion and have DSS motor mounts!! Hoping the Holley stuff will fit

 

I'm helping a friend swap a LS3 into a 1964 Chevelle and we just set the engine in place for the first time yesterday. He used the Holley forward motor mounts and the 302-2 pan and the engine fit like it was made for it. From what I've read on the Chevelle Boards, some have been able to use different factory brackets for the power steering pump, alternator and A/C compressor, but it takes a lot of trial and error to find what will fit and what won't. The Chevy Performance Catalog has a kit that includes the brackets, PS pump, alternator, A/C compressor and idler pulleys for somewhere around $1800. From what I've read, the Holley brackets don't come as a kit with all the idler pulleys and you'll have to find the components that will fit. They do give a list of part numbers that should work with their brackets, though. Both Holley and GM give measurements from the centerline of the crank to the edges of the different pulleys which should allow a person to figure out if they have the clearances to work in their circumstances. I know you can download the Holley specs online and I think the GM system specs are also available too. I know that they are in the printed catalog.
