Re: LY6 6.0 into an '85 C10 Suburban

I thought if you got rid of the DBW and went DBC (along with the getting rid of the VVT) that there were brackets and cables available to use a 700R4? Not sure how you'd best make both these ECM changes though. Use an LS3 ECM? Surely you wouldn't have to swap it to a genIII PCM and related hardware.

Not sure I'd get rid of the VVT tho if you're keeping the EFI. And I'd probably also go with a 6L80 if I was running EFI with ECM control and had a genIV motor... capable of running a 6L80e.
