Re: 5.3 Litre LS Conversion to a carb?

It'll be an e38 ecm...which I heard was one of the latest and greatest, and will run about any trans including a 6L80e or 6L90e...so most likely? No reason couldn't do a speed density tune with that setup? Unless the TB has MAF, IAT, etc. sensors built in?

I'm not against going aftermarket tho.

and no reason to change fuel tank....an inline pump can be placed outside the tank. Same thing FAST and MSD use with their carb style efi. That's my plan.
