Installing ICT Billet LS Motor Mount Adapters
Installing an LS into your muscle car isn’t extraordinarily difficult nowadays, but parts that make these swaps even easier are always welcomed. ICT Billet’s LS adapter plates allow you to bolt your LS in place of your original small block Chevy with ease.
For the price of the adapter plates, there almost isn’t any reason NOT to go this route. They are machined from aerospace grade aluminum, and include the countersunk stainless hardware to bolt them to the block, as well as the bolts to mount a standard small block Chevy motor mount in one of 4 different locations. I decided to use our solid motor mounts (part number 54562500), however you can use rubber, poly, or even the later style clamshell motor mounts with these adapters. I chose these mounts as I didn’t want any deflection, and in this particular car comfort is not a necessity. The additional vibrations from the engine will not bother me the slightest bit as this is a track oriented build.
The best part about these mounts is that they’re nearly impossible to mix up, as they are labeled for the driver’s or passenger’s side. Simply bolt them to the block, and choose the correct location for your motor mounts. I chose the furthest forward location, as this is going to be the closest to stock location available with a flat adapter. In my case that didn’t matter as I had to fabricate some lower mount tabs for my oil pan to clear my center link. Be sure not to over tighten these, as even though they are a very good quality product, they are still aluminum and can be stripped fairly easily with excessive force.
After dropping it in by starting with the furthest back location, you can always move it forward if you need the firewall or header clearance. Do keep in mind that all adapter plates of this style will move your crankshaft centerline up slightly, .177” in this case. That’s not enough to cause any issues with my low buck build, but it is worth noting if hood clearance is a big issue.
I’ve used these brackets in almost every LS swap that I can. For what they cost, you simply can’t beat the quality and ease of installation that these brackets offer.
