63-66 LS swap guys - best mounts? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a 1965 C10 that came with a 230 inline 6 and powerglide. I’ve removed both of those and have a 5.3L and 4L60E to go in. I’ve seen the Holley and CPP kits, but that’s some serious dough just to mount this thing.

I basically have three questions:

1. Can the stock frame mounts and crossmember be used to mount the engine/trans and have a good working U-joint angle?

2. If this is possible, are stock inline 6 frame mounts different than the stock V8 frame mounts?

3. What additional mounts/adapters would be needed?
