I spent a couple of hours on hold the last 2 days trying to get someone on the phone at Holley.
I was then told they had no idea of a time frame for availability...

The forward position also improves the installation situation in relation to 4L80/4L85 transmissions, but for different reasons. These transmissions have smooth cast one-piece bellhousings/cases like the GM legacy transmissions, but they are longer overall than the length of the transmission fitment well designed into the tunnel of the car by GM.

It just so happens that using the Hooker forward-bias engine brackets moves the rear of the case of the 4L80/4L85 transmissions case forward of the end of the well and allows the trans to tuck up into the well just as a TH400 does when installed in a 64-67 A-body.

Todd,

Very excited to use this system. I have a '65 Elk getting a LQ4, LS3 heads, 4L80, & 10 bolt. Suspension is a 1" spring drop front and rear. Stock spindles up front. My trans tunnel has already been modified (stretched) to accommodate the 4L80, so I don't think I will have fitment issues with either mounts.

Regarding your comment above - My cobbled together system is going to punish me on driveline angle, but it seems this system will be the answer. Since the Elk uses the same cross member as the convertible, when do you expect it to be available?

The brackets have not yet been loaded on our website and the product release has not yet been sent out to our resellers, which means there are no allocations for orders currently. If you monitor the Holley website daily starting next week and place an order as soon as you see them present there, then you would more or less guarantee that you would receive a set out of the first production run. The part numbers are 71221008HKR for the forward-bias brackets and 71221009HKR for the rear-bias brackets.

Todd, any updates on when the mounts will come out? I've looked at the website and so far haven't seen the mounts out there. Also how far away are the headers from being introduced and any idea on the timing for the cross member for convertibles?

Thx,

Ted

I've been keeping an eye out too and i just noticed they are now listed on Summit's website:

Any update?

Wait, where do the turbos go?

 

[rocket66]

My engine mounts ordered from Summit shipped today...!

 

[mytmouz]

Post up the non Summit part numbers when they come in. I refuse to let Summit get another dime from me ever again...

I wonder what happened, Todd hasn't posted anything since July 4th...1 month

 

[mytmouz]

He is updating threads on other boards as I type this with relavent information. He should be along shortly...

 

[mytmouz]

Since we didn't get an update here yet...

There is progress to report on the release of the parts. The engine brackets were released into the system on Friday and there are sets of both the forward bias and rear bias versions on the shelf; the part numbers for the engine brackets are 71221008HKR and 71221009HKR. They shound be listed on the Holley website and be available for purchase sometime next week. The transmission crossmembers have been delivered to our distribution facility and are waiting for our internal documentation process to catch up with them so they can be boxed up and put on the shelf...I'm going to guess 1.5 weeks for that to happen. I've been informed by the production lead that the first production run of the 1-7/8" long tube headers should take place the week after next.

I received a set of forward biased brackets late last week. I ordered them though summit racing when I first saw them on their website in early July. Interestingly when the first came out they were $124.95 and now they're $149.95.

Here's some pics of the forward biased mounts. Ted

Todd,

Any update on the cross member for the boxed framed vehicles - El Camino & Convertables?

 

[senna]

Anybody have any updates, started their install with this kit?

Over 2 months now..I wonder what's going on with him

 

[mytmouz]

Probably the new log in. He is posting on other sites...

Could you please provide the other site names he posts on, I'm pretty sure I'm not the only one that would like to follow along

 

[mytmouz]

Not sure how the moderators feel about that. If they are fine with it, no problem...

 

[mytmouz]

This was the latest post to whet your appetites though...

The part numbers for what's been released thus far is as follows:

71221008HKR- forward bias engine brackets
71221009HKR- rear bias engine brackets
71222008HKR- transmission crossmember
70201311-RHKR- 1-3/4" stainless mid-length headers
70201312-RHKR- 1-7/8" stainless mid-length headers
70101335-RHKR- 1-3/4" stainless long-tube headers
70101336-RHKR- 1-7/8" stainless long-tube headers

All of these parts are listed on the Holley website now with supporting information.

The first article production sample of the 3" exhaust system was built last week from the first run of production bends without any issues. This means production of the first batch gets a green light and I'm hopeful they will get welded and boxed up this coming week. The 2.5" systems are still a few weeks out as production bends have not been produced yet.
