    Vortec headed tbi to carb swap - wiring and 700r4 lockup

    Yes it already together and used it because I was trying to use up some spare parts and still keep it TBI compatible Good idea. I'll check there. It still runs lockup without a tps signal? Sounds like it's getting bypassed. Easy enough to keep an eye on the oil pressure gauge.

    Vortec headed tbi to carb swap - wiring and 700r4 lockup

    I do not have a wideband 02. Guessing by reading spark plugs. Tips light grey, end of porcelain light tan, base of porcelain jet black.

    Vortec headed tbi to carb swap - wiring and 700r4 lockup

    Sorry if this isn't the right place but I've been searching for weeks and haven't found the answers I'm looking for. I have a 1990 scsb z71 that I bought with a knocking engine so I put together a bunch of spare sbc parts I have accumulated over the years with the goal of 375hp. Engine is...
