Holley Engine Mounts - question

[TripleBlk70]

I see people talking about Holley Engine mounts for their Gen 3 hemi and looking on their site I see these:

Hooker Blackheart Engine Mount Brackets�
https://www.holley.com/products/engine_swap_parts/hemi_swap_systems/parts/BHS566

Which are not Holley branded obviously. Are these the right ones for a 392/6.4L hemi? Looks like it based on the description but if there's something else better that people are using I'd appreciate any direction or feedback.

Blackheart is a division of Holley.
These mounts move the engine forward about 1.5 inches.
I get rid of mine and got TTI mounts and headers.

Plan out your swap, if you go with Holley mounts, most likely will need to use their headers.
I bought the Holley mounts,then found out they wouldn't work with my TTI headers.
IMO, the TTI mounts/headers are a better route.
Keeps the engine in stock position, so no issues with exhaust and transmission.

Funny I did the same thing. Got rid of the Blackhart mounts and Holley SS headers and went TTI.
I found the TTI header's outlet flange hangs way low down below the k-frame and oil pan. You can get the 6-degree offset collectors from TTI special order i think to kick the collector pipe back-up a bit. But the headers flanges will still be so LOW.
I raised-up the back of the transmission (and motor) about 3 degrees to get the header flanges tucked-up higher and to get the angle speced for the TKX 5-speed.
Raising the trans/engine rear to lift the header flange up close to the floorboards required me to cut the tranny crossmember and box it and had to mod top right side of the tunnel to clear the top right corner of the tranny case.
In fact, I pulled the whole tunnel and got a holley tremec 6-speed tunnel kit and modified that. it all fits but i will need to shim the rear axle 3-degrees now to match the engine/tranny angle.
You could use the stock trans crossmember without modification I believe but the TTI headers flange will hang low.

The Holley engine mount thing...Yes they are from Hooker/Blackheart which is a Holley division.  In an e-body, the Holley mounts move the engine forward one-inch.  This provides clearance for the 8HP70 auto trans and NAG1 that alot of people run.  No need to cut the trans tunnel with these mounts and the 8HP70 trans.  Makes for a relatively easy swap.  Holley has a lot of stuff in their collection of brands, that make the swap a bit easier.

The header thing, Hooker/Holley had a nice set of stainless headers for the e-body, but discontinued them.  Rumor has it some sort of EPA crackdown issue.  They do have exhaust manifolds that will work.  Some want headers, some don't want the hassle that sometimes comes with headers.

If you're doing a swap, do your homework upfront.  Figure what works with what before you head down an expensive path and find out some of what you have doesn't work.
