Mount and Crossmember Conversion Kit for LS3 I was going to get this BRP/Muscle Rod mount and crossmember kit to get my E-ROD LS3/4L65E installed in my 78 Trans Am.
I never really looked at options until today and found a review by an unsatisfied customer who was told by the company that it would work for his car but because he did not also get the headers from BRP that it did not match and so he had fitment issues and had to spend another $500 on their headers.
My E-ROD LS3/4L65E comes with GM headers.
Will I have any issues with the BRP?

Here is the installation manual:

Or should I get the Holley or some other brand? What are all the parts I need that match up with the BRP parts?
Here is the Holley page for mounts:
https://www.holley.com/products/ls_p...ission_mounts/
What from Holley would I need?
I am guessing these and ONLY these parts, or more parts from Holley?? :

Above states I need the below, but how many? Is this exactly the correct item?

I would go with the Holley mounts. Since you have a 78, use these:

So does that mean it will not work with the GM headers that come with the LS3??

Reading the manual:
"Due to the exclusive geometry designed into these HOOKERTM engine swap mounting brackets, attempts to install headers and/or transmission crossmembers other than those developed by HOOKERTM will not be successful."
So what do I buy then?

Does your E-Rod engine come with HEADERS or stock MANIFOLDS? Different headers are a hassle as they are all bent differently. Stock manifolds on the other hand fit very close to the engine, and should not be a hassle like headers can be.
