5.3 vortec in my 61 c10 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Bad61c10 · 06-28-2016, 01:26 AM

Hey guys I'm looking to swap the engine that's in my truck right now to a 5.3 vortec and I'm wondering if I need to buy engine mounts and what other things I will need to do the swap. I currently have a 327 and have been told that the block is the same between the 327 and the 5.3 so can anyone tell me if I need to buy new motor mounts, if so where's the best place to buy them. While I am doing this I will be putting the front crossmember from an 81 GMC Sierra. Thanks in advance!

I am going to move this over to the LS swap area. No, they are not the same in any way, shape or form. LSx (4.8, 5.3, 6.0) share nothing with the earlier blocks. You will need different mounts and a number of other things.

Welcome to the forum!

First off, you will need a ton of stuff so I am not going to bore you with a list of things you might or might not need.

Ready through this, it will fill you in and get you started well.
