Who has done a 5.7 with a833 4 speed Overdrive ?

I assume you plan to keep the truck TC cover then?

And to be clear, it is only the car 6.4 intake that has an issue with the SRV module. The truck 6.4 intake has the module on the front of the intake, so if you run that intake you can keep the functionality.

I don't have any experience with aftermarket cams, sorry. I have a stock 6.4 non-MDS cam to go into my 5.7 because it is relatively cheap and I think it's the cam the 5.7 should have come with in the factory R/T cars. But I haven't done anything with aftermarket stuff nor have I even researched them.
I will try and keep the the truck timing cover and see how it does for hood clearance with the alternator when I test fit it. Worst case I'll get the Holley one. I was also going to get the Holley fuel tank system and terminator X to go along with it. What are you going to run?

Sounds good on the cam. That was my plan, to just do the 6.4 non-mds cam, tti engine mounts/headers and the 6.4 intake for the 5.7 mods. From my research that seems to be the most practical for easy hp mods.
