How to: Ruin a perfectly good C10

Throttle body is a 92mm from Warr Performance. Pretty much the same China version that lots of sellers have available, but Warr takes the time to fix the minor issues that many of them have so that it’s a bolt-on, no hassle affair. Again, google/forums say it’s good, we’ll see. Looks/feels like a nice part in my hands.

For the harness/ECM I was planning on using GM, but just picked up a FiTech standalone 70050. This lets me delete the MAF which was making the air cleaner sit too high, while utilizing all of the other factory sensors/coils/injectors, etc. It also uses wideband O2s which should theoretically make tuning easier/faster.

The main reason for grabbing the FiTech was time savings as reworking the stock harness and ECM would be very time consuming and I gotta get this beast going before we move next summer. If I was running a stock engine, stock stuff would be a no-brainer, but I gotta be difficult If it sucks/I hate it, I can always go back to GM or Holley for a harness/ECM, though both of those options are more expensive and/or take longer to get going.

Thanks for the info on the paint, how many cans did you use on your engine? The reason I ask these questions is that we are picking up an LS1 this weekend and I'm not 100% sure how we'll outfit it in our truck. We have the FiTech Go EFI 4 600hp throttle body unit on our 350/700r4 set up, so an LS1/700r4 with the throttle body is a possibility. The self learning capacity is a huge attribute but it also a limiting factor. Getting help from a local tuner is impossible because they can't use HP Tuners or the like and don't want to tune it the hard way. Money, as always, will have an influence on the decisions but overall performance and tune-ability will be first and foremost. The first decision we've made is of course to use the LS1 long block. The second decision is to use the competent but much less expensive Holley accessory drive versus the Billet Specialties system we have on our 350. The third absolute is the use of Hooker LS manifolds, so clean and simple. Beyond those three decisions, I've yet to decide weather we will keep the current FiTech system with the 700r4, swap to the FiTech Retro LS system, use the Delmo throttle body adapter on a carb manifold, or use the stock LS1 manifold and throttle body. Needless to say there is some decision making in our future. I really like the old school look of a carb, especially on an LS (I don't like the look of the intake tube) so that may be a major factor. We'll have to see where it goes... Anyway, you've got great momentum, keep up the great work!
