Hey Class01. I am in the same boat. There are tons of threads to read, but on my side I don't want to order wrong parts and have to go through that hassle. I am a question asker, the guys on here have been very helpful. I am using Dirty Dingo slider mounts, and CPP sheet metal perches. Will you be running headers or manifolds? One thing to consider is if you will be using A/C and where you will mount it. You can relocate the A/C to upper passenger head through a few options. Dirty Dingo has one, but they are pricey, Holley has another option. I would suggest taking a look at this thread, tells what mount everybody has used, motor and trans, as well as fuel tank and radiator. It will give you a consensus.
