4L80E transmission mount

What transmission mount are you guys using for an 4L80E in a first gen Camaro? Holley may make one and I could be over looking it. I see several for the 6 speeds and 4L60E...

This dude is a beast and the mount is pretty far back. I thought about moving the mount location back on the subframe but I don't want it in the way of the parking brake cable.

It does look like a nice piece... I like how they made room for the exhaust.

Guys, how much trouble did you have getting the 4L80e installed ?

Should I get a 4 lb hammer and start expanding the trans tunnel ?

It's tight with a stock tunnel. I had a buddy with a big block that said it barely fit, but he didn't have to beat it. At the time, Holley didn't make a 4L80E cross member. I'm curious what degree his engine was sitting. I've read that it's tight enough that you need full height(stock) body mounts.
The holley engine mounts put the engine a touch lower and the passenger head is about 1.5" off the firewall, so the clearance should be better. I think it can be done pretty easily.

Thanks for the info Shad. I will be buying the entire Holley kit for my LS3/4L80e swap.

G-Force Crossmember. Bolts right in. Super beefy. Sits tight to the body for good exhaust clearance.

Re: 4L80E transmission mount

This is the one I had.

1968-1974 NOVA / VENTURA CROSSMEMBER - 4L80 - RCF1-4L80 - X-BODY, NOVA, VENTURA

The tranmission was behind a SBC 400. Mounted right up to the subframe holes. Dont know if it would match up if you are doing a LS... Might have to drill new holes?
